T-REX 2X LONG AVAV DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of AVAV’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AVAV during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how AVAV volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) AVAV volatility; b) AVAV performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to AVAV. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of AVAV volatility and AVAV performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to AVAV; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of AVAV.

 

During periods of higher AVAV volatility, the volatility of AVAV may affect the Fund’s return as much as, or more than, the return of AVAV. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AVAV during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if AVAV provided no return over a one-year period during which AVAV experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if AVAV’s return is flat. For instance, if AVAV’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of AVAV and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of AVAV. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

AVAV’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 52.81%. AVAV’s annualized daily volatility rates were as follows:

 

2020       52.69%

2021       58.60%

2022       56.70%

2023       41.23%

2024       53.33%

 

Volatility for a shorter period of time may have been substantially higher.

 

AVAV’s annualized performance for the five-year period ended December 31, 2024 was 20.02%. Historical volatility and performance are not indications of what AVAV volatility and performance will be in the future. AVAV’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for AVAV is $295.90 on June 30, 2025 and the 52-week low stock price for AVAV is $102.25, which occurred on April 7, 2025. AVAV’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG AVAV DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of AVAV will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in AVAV, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if AVAV subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if AVAV does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AVAV and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG AVAV DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG AVAV DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG AVAV DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

T-REX 2X LONG AVAV DAILY TARGET ETF | FLEX Options [Member]

Risk [Text Block]

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG AVAV DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of AVAV, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

T-REX 2X LONG AVAV DAILY TARGET ETF | Rebalancing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to AVAV that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG AVAV DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of AVAV at the market close on the first trading day and the value of AVAV at the time of purchase. If AVAV gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if AVAV declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of AVAV.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG AVAV DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to AVAV and therefore achieve its daily leveraged investment objective. The Fund’s exposure to AVAV is impacted by AVAV’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to AVAV at the end of each day. The possibility of the Fund being materially over- or under-exposed to AVAV increases on days when AVAV is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) AVAV. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with AVAV. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to AVAV. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of AVAV. Any of these factors could decrease the correlation between the performance of the Fund and AVAV and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

AVAV Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, AVAV faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of AVAV common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of AVAV’s] common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. AVAV is a highly dynamic company, and its operations, including its products and services, may change.

T-REX 2X LONG AVAV DAILY TARGET ETF | Industrials Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Industrials Sector Risk. The Fund’s assets will be concentrated in the industrials sector, which means the Fund will be more affected by the performance of the industrials sector than a fund that is more diversified. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

Industry Concentration Risk. The Fund will be concentrated in the industry to which AeroVironment, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which AeroVironment, Inc. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, AVAV is assigned to the industrials sector and the aerospace & defense industry.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG AVAV DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with AVAV. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that AVAV value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the AVAV. Under such circumstances, the market for AVAV may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of AVAV and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for AVAV and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of AVAV and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with AVAV and may incur substantial losses. If there is a significant intra-day market event and/or AVAV experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of AVAV does not provide leveraged exposure to AVAV and, as a result, if the Fund invests directly in common stock of AVAV to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG AVAV DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG AVAV DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]

Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

T-REX 2X LONG AVAV DAILY TARGET ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG AFRM DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of AFRM’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AFRM during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how AFRM volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) AFRM volatility; b) AFRM performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to AFRM. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of AFRM volatility and AFRM performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to AFRM; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of AFRM.

 

During periods of higher AFRM volatility, the volatility of AFRM may affect the Fund’s return as much as, or more than, the return of AFRM. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AFRM during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if AFRM provided no return over a one-year period during which AFRM experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if AFRM’s return is flat. For instance, if AFRM’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of AFRM and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of AFRM. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

AFRM’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 114.09%. AFRM’s annualized daily volatility rates were as follows:

 

2021       141.96%

2022       126.61%

2023       98.91%

2024       78.36%

 

Volatility for a shorter period of time may have been substantially higher.

 

AFRM’s annualized performance for the five-year period ended December 31, 2024 was 5.63%. Historical volatility and performance are not indications of what AFRM volatility and performance will be in the future. AFRM’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for AFRM is $82.53 on February 18, 2025 and the 52-week low stock price for AFRM is $22.25, which occurred on August 5, 2024. AFRM’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG AFRM DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of AFRM will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in AFRM, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if AFRM subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if AFRM does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AFRM and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG AFRM DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG AFRM DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG AFRM DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG AFRM DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of AFRM, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to AFRM that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG AFRM DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of AFRM at the market close on the first trading day and the value of AFRM at the time of purchase. If AFRM gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if AFRM declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of AFRM.

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG AFRM DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to AFRM and therefore achieve its daily leveraged investment objective. The Fund’s exposure to AFRM is impacted by AFRM’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to AFRM at the end of each day. The possibility of the Fund being materially over- or under-exposed to AFRM increases on days when AFRM is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) AFRM. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with AFRM. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to AFRM. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of AFRM. Any of these factors could decrease the correlation between the performance of the Fund and AFRM and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, AFRM is assigned to the technology sector and the software-infrastructure industry.

T-REX 2X LONG AFRM DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

T-REX 2X LONG AFRM DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with AFRM. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that AFRM value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the AFRM. Under such circumstances, the market for AFRM may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of AFRM and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for AFRM and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of AFRM and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with AFRM and may incur substantial losses. If there is a significant intra-day market event and/or AFRM experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of AFRM does not provide leveraged exposure to AFRM and, as a result, if the Fund invests directly in common stock of AFRM to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG AFRM DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG AFRM DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

AFRM Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, AFRM faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of AFRM common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of AFRM’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. AFRM is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

Computer Software Industry Risk. Computer software companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer software companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of computer software companies depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results. Many computer software companies rely on a combination of patents, copyrights, trademarks, and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer software companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

 

T-REX 2X LONG ACHR DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of ACHR’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of ACHR during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how ACHR volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) ACHR volatility; b) ACHR performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to ACHR. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of ACHR volatility and ACHR performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to ACHR; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of ACHR.

 

During periods of higher ACHR volatility, the volatility of ACHR may affect the Fund’s return as much as, or more than, the return of ACHR. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of ACHR during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if ACHR provided no return over a one-year period during which ACHR experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if ACHR’s return is flat. For instance, if ACHR’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of ACHR and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of ACHR. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

ACHR’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 82.42%. ACHR’s annualized daily volatility rates were as follows:

 

2020       29.66%

2021       55.76%

2022       90.05%

2023       94.27%

2024       84.96%

 

Volatility for a shorter period of time may have been substantially higher.

 

ACHR’s annualized performance for the five-year period ended December 31, 2024 was -0.55%. Historical volatility and performance are not indications of what ACHR volatility and performance will be in the future. ACHR’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for ACHR is $13.92 on May 16, 2025 and the 52-week low stock price for ACHR is $2.82, which occurred on September 26, 2024. ACHR’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG ACHR DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of ACHR will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in ACHR, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if ACHR subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if ACHR does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with ACHR and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG ACHR DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG ACHR DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG ACHR DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG ACHR DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of ACHR, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to ACHR that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG ACHR DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of ACHR at the market close on the first trading day and the value of ACHR at the time of purchase. If ACHR gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if ACHR declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of ACHR.

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG ACHR DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to ACHR and therefore achieve its daily leveraged investment objective. The Fund’s exposure to ACHR is impacted by ACHR’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to ACHR at the end of each day. The possibility of the Fund being materially over- or under-exposed to ACHR increases on days when ACHR is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) ACHR. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with ACHR. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to ACHR. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of ACHR. Any of these factors could decrease the correlation between the performance of the Fund and ACHR and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Risk [Text Block]

Industrials Sector Risk. The Fund’s assets will be concentrated in the industrials sector, which means the Fund will be more affected by the performance of the industrials sector than a fund that is more diversified. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with ACHR. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that ACHR value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the ACHR. Under such circumstances, the market for ACHR may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of ACHR and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for ACHR and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of ACHR and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with ACHR and may incur substantial losses. If there is a significant intra-day market event and/or ACHR experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of ACHR does not provide leveraged exposure to ACHR and, as a result, if the Fund invests directly in common stock of ACHR to a greater extent, the Fund may not achieve its 200% daily investment objective.

Risk [Text Block]

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG ACHR DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG ACHR DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange.

ACHR Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, ACHR faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of ACHR common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of ACHR’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. ACHR is a highly dynamic company, and its operations, including its products and services, may change.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG AUR DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of AUR’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AUR during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how AUR volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) AUR volatility; b) AUR performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to AUR. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of AUR volatility and AUR performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to AUR; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of AUR.

 

During periods of higher AUR volatility, the volatility of AUR may affect the Fund’s return as much as, or more than, the return of AUR. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AUR during a shareholder’s holding period of an investment in the Fund.

 

 

As shown in the chart below, the Fund would be expected to lose 6.1% if AUR provided no return over a one-year period during which AUR experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if AUR’s return is flat. For instance, if AUR’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of AUR and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of AUR. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

AUR’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 91.74%. AUR’s annualized daily volatility rates were as follows:

 

2021       80.86%

2022       97.26%

2023       89.72%

2024       93.84%

 

Volatility for a shorter period of time may have been substantially higher.

 

AUR’s annualized performance for the five-year period ended December 31, 2024 was -11.90%. Historical volatility and performance are not indications of what AUR volatility and performance will be in the future. AUR’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for AUR is $10.77 on February 14, 2025 and the 52-week low stock price for AUR is $3.25, which occurred on August 7, 2024. AUR’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG AUR DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of AUR will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in AUR, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if AUR subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if AUR does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AUR and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG AUR DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG AUR DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG AUR DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG AUR DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of AUR, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to AUR that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG AUR DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of AUR at the market close on the first trading day and the value of AUR at the time of purchase. If AUR gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if AUR declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of AUR.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG AUR DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to AUR and therefore achieve its daily leveraged investment objective. The Fund’s exposure to AUR is impacted by AUR’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to AUR at the end of each day. The possibility of the Fund being materially over- or under-exposed to AUR increases on days when AUR is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) AUR. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with AUR. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to AUR. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of AUR. Any of these factors could decrease the correlation between the performance of the Fund and AUR and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG AUR DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with AUR. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that AUR value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the AUR. Under such circumstances, the market for AUR may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of AUR and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for AUR and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of AUR and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with AUR and may incur substantial losses. If there is a significant intra-day market event and/or AUR experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of AUR does not provide leveraged exposure to AUR and, as a result, if the Fund invests directly in common stock of AUR to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG AUR DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG AUR DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

AUR Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, AUR faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of AUR common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of AUR’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. AUR is a highly dynamic company, and its operations, including its products and services, may change.

Information Technology Risk. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation, and competition, both domestically and internationally, including competition from competitors with lower production costs. In addition, many information technology companies have limited product lines, markets, financial resources, or personnel. The prices of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile and less liquid than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the information technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG AXON DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of AXON’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AXON during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how AXON volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) AXON volatility; b) AXON performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to AXON. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of AXON volatility and AXON performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to AXON; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of AXON.

 

During periods of higher AXON volatility, the volatility of AXON may affect the Fund’s return as much as, or more than, the return of AXON. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of AXON during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if AXON provided no return over a one-year period during which AXON experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if AXON’s return is flat. For instance, if AXON’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of AXON and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of AXON. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

AXON’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 49.94%. AXON’s annualized daily volatility rates were as follows:

 

2020       66.27%

2021       44.61%

2022       52.66%

2023       36.15%

2024       44.92%

 

Volatility for a shorter period of time may have been substantially higher.

 

AXON’s annualized performance for the five-year period ended December 31, 2024 was 51.92%. Historical volatility and performance are not indications of what AXON volatility and performance will be in the future. AXON’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for AXON is $830.21 on June 30, 2025 and the 52-week low stock price for AXON is $279.02, which occurred on August 5, 2024. AXON’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG AXON DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of AXON will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in AXON, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if AXON subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if AXON does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AXON and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG AXON DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG AXON DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG AXON DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG AXON DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of AXON, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to AXON that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG AXON DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of AXON at the market close on the first trading day and the value of AXON at the time of purchase. If AXON gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if AXON declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of AXON.

 

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG AXON DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to AXON and therefore achieve its daily leveraged investment objective. The Fund’s exposure to AXON is impacted by AXON’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to AXON at the end of each day. The possibility of the Fund being materially over- or under-exposed to AXON increases on days when AXON is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) AXON. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with AXON. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to AXON. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of AXON. Any of these factors could decrease the correlation between the performance of the Fund and AXON and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Risk [Text Block]

Industrials Sector Risk. The Fund’s assets will be concentrated in the industrials sector, which means the Fund will be more affected by the performance of the industrials sector than a fund that is more diversified. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG AXON DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with AXON. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that AXON value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the AXON. Under such circumstances, the market for AXON may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of AXON and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for AXON and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of AXON and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with AXON and may incur substantial losses. If there is a significant intra-day market event and/or AXON experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of AXON does not provide leveraged exposure to AXON and, as a result, if the Fund invests directly in common stock of AXON to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG AXON DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG AXON DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

AXON Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, AXON faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of AXON common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of AXON’S common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG B DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of B’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of B during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how B volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) B volatility; b) B performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to B. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of B volatility and B performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to B; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of B.

 

During periods of higher B volatility, the volatility of B may affect the Fund’s return as much as, or more than, the return of B. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of B during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if B provided no return over a one-year period during which B experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if B’s return is flat. For instance, if B’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of B and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of B. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

B’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 36.68%. B’s annualized daily volatility rates were as follows:

 

2020       48.46%

2021       29.66%

2022       39.28%

2023       29.02%

2024       33.52%

 

Volatility for a shorter period of time may have been substantially higher.

 

B’s annualized performance for the five-year period ended December 31, 2024 was -3.57%. Historical volatility and performance are not indications of what B volatility and performance will be in the future. B’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for B is $21.70 on June 16, 2025 and the 52-week low stock price for B is $15.11, which occurred on December 19, 2024. B’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG B DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of B will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in B, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if B subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if B does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with B and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG B DAILY TARGET ETF | Swap Agreements [Member]

Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist.

A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of B, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to B that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG B DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of B at the market close on the first trading day and the value of B at the time of purchase. If B gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if B declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of B.

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG B DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to B and therefore achieve its daily leveraged investment objective. The Fund’s exposure to B is impacted by B’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to B at the end of each day. The possibility of the Fund being materially over- or under-exposed to B increases on days when B is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) B. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with B. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to B. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of B. Any of these factors could decrease the correlation between the performance of the Fund and B and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Barrick Mining Corporation is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Barrick Mining Corporation is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, B is assigned to the basic materials sector and the gold industry.

T-REX 2X LONG B DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG B DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with B. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that B value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the B. Under such circumstances, the market for B may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of B and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for B and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of B and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with B and may incur substantial losses. If there is a significant intra-day market event and/or B experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of B does not provide leveraged exposure to B and, as a result, if the Fund invests directly in common stock of B to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG B DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG B DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

B Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, B faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of B common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of B’S common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. B is a highly dynamic company, and its operations, including its products and services, may change.

Materials Sector Risk. The Fund’s assets will be concentrated in the materials sector, which means the Fund will be more affected by the performance of the materials sector than a fund that is more diversified. Many materials companies are significantly affected by the level and volatility of commodity prices, exchange rates, import controls, worldwide competition, environmental policies and consumer demand. At times, worldwide production of industrial materials has exceeded demand as a result of over-building or economic downturns, leading to poor investment returns or losses. Other risks may include liabilities for environmental damage and general civil liabilities, depletion of resources, and mandated expenditures for safety and pollution control. The materials sector may also be affected by economic cycles, technical progress, labor relations, and government regulations.

Gold and Silver Mining Companies Risk. Gold mining and silver mining industries are considered speculative and are affected by a variety of factors. Competitive pressures may have a significant effect on the financial condition of gold mining and silver mining companies. Also, gold and silver mining companies are highly dependent on the price of gold bullion and silver bullion, respectively, but may also be adversely affected by a variety of worldwide economic, financial and political factors. The price of gold and silver may fluctuate substantially over short periods of time so the Fund’s share price may be more volatile than other types of investments. Fluctuation in the prices of gold and silver may be due to a number of factors, including changes in inflation, changes in currency exchange rates and changes in industrial and commercial demand for metals (including fabricator demand). Additionally, increased environmental or labor costs may depress the value of metal investments.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG BBAI DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of BBAI’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BBAI during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how BBAI volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) BBAI volatility; b) BBAI performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to BBAI. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of BBAI volatility and BBAI performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to BBAI; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of BBAI.

 

During periods of higher BBAI volatility, the volatility of BBAI may affect the Fund’s return as much as, or more than, the return of BBAI. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BBAI during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if BBAI provided no return over a one-year period during which BBAI experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if BBAI’s return is flat. For instance, if BBAI’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of BBAI and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of BBAI. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

BBAI’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 177.58%. BBAI’s annualized daily volatility rates were as follows:

 

2021       39.24%

2022       115.73%

2023       297.85%

2024       121.72%

 

Volatility for a shorter period of time may have been substantially higher.

 

BBAI’s annualized performance for the five-year period ended December 31, 2024 was -19.08%. Historical volatility and performance are not indications of what BBAI volatility and performance will be in the future. BBAI’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for BBAI is $10.36 on February 13, 2025 and the 52-week low stock price for BBAI is $1.17, which occurred on August 5, 2024. BBAI’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG BBAI DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of BBAI will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in BBAI, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if BBAI subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if BBAI does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with BBAI and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG BBAI DAILY TARGET ETF | Call Options [Member]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG BBAI DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of BBAI, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to BBAI that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG BBAI DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of BBAI at the market close on the first trading day and the value of BBAI at the time of purchase. If BBAI gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if BBAI declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of BBAI.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG BBAI DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to BBAI and therefore achieve its daily leveraged investment objective. The Fund’s exposure to BBAI is impacted by BBAI’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to BBAI at the end of each day. The possibility of the Fund being materially over- or under-exposed to BBAI increases on days when BBAI is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) BBAI. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with BBAI. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to BBAI. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of BBAI. Any of these factors could decrease the correlation between the performance of the Fund and BBAI and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with BBAI. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that BBAI value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the BBAI. Under such circumstances, the market for BBAI may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of BBAI and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for BBAI and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of BBAI and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with BBAI and may incur substantial losses. If there is a significant intra-day market event and/or BBAI experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of BBAI does not provide leveraged exposure to BBAI and, as a result, if the Fund invests directly in common stock of BBAI to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG BBAI DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

BBAI Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, BBAI faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of BBAI common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of BBAI’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG BKNG DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of BKNG’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BKNG during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how BKNG volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) BKNG volatility; b) BKNG performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to BKNG. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of BKNG volatility and BKNG performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to BKNG; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of BKNG.

 

During periods of higher BKNG volatility, the volatility of BKNG may affect the Fund’s return as much as, or more than, the return of BKNG. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BKNG during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if BKNG provided no return over a one-year period during which BKNG experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if BKNG’s return is flat. For instance, if BKNG’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of BKNG and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of BKNG. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

BKNG’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for BKNG is $5,839.41 on July 8, 2025 and the 52-week low stock price for BKNG is $3,180.00, which occurred on August 5, 2024. BKNG’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG BKNG DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of BKNG will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in BKNG, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if BKNG subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if BKNG does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with BKNG and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG BKNG DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG BKNG DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG BKNG DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG BKNG DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of BKNG, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to BKNG that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG BKNG DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of BKNG at the market close on the first trading day and the value of BKNG at the time of purchase. If BKNG gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if BKNG declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of BKNG.

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG BKNG DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to BKNG and therefore achieve its daily leveraged investment objective. The Fund’s exposure to BKNG is impacted by BKNG’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to BKNG at the end of each day. The possibility of the Fund being materially over- or under-exposed to BKNG increases on days when BKNG is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) BKNG. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with BKNG. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to BKNG. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of BKNG. Any of these factors could decrease the correlation between the performance of the Fund and BKNG and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, BKNG is assigned to the consumer discretionary sector and the travel services industry.

T-REX 2X LONG BKNG DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with BKNG. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that BKNG value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the BKNG. Under such circumstances, the market for BKNG may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of BKNG and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for BKNG and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of BKNG and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with BKNG and may incur substantial losses. If there is a significant intra-day market event and/or BKNG experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of BKNG does not provide leveraged exposure to BKNG and, as a result, if the Fund invests directly in common stock of BKNG to a greater extent, the Fund may not achieve its 200% daily investment objective.

As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG BKNG DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG CVNA DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of CVNA’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CVNA during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how CVNA volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) CVNA volatility; b) CVNA performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to CVNA. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of CVNA volatility and CVNA performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to CVNA; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of CVNA.

 

During periods of higher CVNA volatility, the volatility of CVNA may affect the Fund’s return as much as, or more than, the return of CVNA. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CVNA during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if CVNA provided no return over a one-year period during which CVNA experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if CVNA’s return is flat. For instance, if CVNA’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of CVNA and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of CVNA. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

CVNA’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 117.73%. CVNA’s annualized daily volatility rates were as follows:

 

2020       113.43%

2021       51.33%

2022       154.80%

2023       152.52%

2024       78.00%

 

Volatility for a shorter period of time may have been substantially higher.

 

CVNA’s annualized performance for the five-year period ended December 31, 2024 was 17.16%. Historical volatility and performance are not indications of what CVNA volatility and performance will be in the future. CVNA’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for CVNA is $364.00 on July 8, 2025 and the 52-week low stock price for CVNA is $118.50, which occurred on August 5, 2024. CVNA’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG CVNA DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of CVNA will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in CVNA, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if CVNA subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if CVNA does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with CVNA and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG CVNA DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG CVNA DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG CVNA DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

Risk [Text Block]

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG CVNA DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of CVNA, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Risk [Text Block]

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to CVNA that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG CVNA DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of CVNA at the market close on the first trading day and the value of CVNA at the time of purchase. If CVNA gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CVNA declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of CVNA.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG CVNA DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to CVNA and therefore achieve its daily leveraged investment objective. The Fund’s exposure to CVNA is impacted by CVNA’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to CVNA at the end of each day. The possibility of the Fund being materially over- or under-exposed to CVNA increases on days when CVNA is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) CVNA. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with CVNA. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to CVNA. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of CVNA. Any of these factors could decrease the correlation between the performance of the Fund and CVNA and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

The Fund will be concentrated in the industry to which Carvana Co. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Carvana Co. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, CVNA is assigned to the consumer discretionary sector and the automotive industry.

T-REX 2X LONG CVNA DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG CVNA DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with CVNA. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that CVNA value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the CVNA. Under such circumstances, the market for CVNA may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of CVNA and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for CVNA and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of CVNA and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with CVNA and may incur substantial losses. If there is a significant intra-day market event and/or CVNA experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Risk [Text Block]

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of CVNA does not provide leveraged exposure to CVNA and, as a result, if the Fund invests directly in common stock of CVNA to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG CVNA DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and global economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on the irrespective profitability.

In addition to the risks associated generally with operating companies, CVNA faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of CVNA common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of CVNA’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price.

Automotive companies may be significantly subject to government policies and regulations regarding imports and exports of automotive products. Governmental policies affecting the automotive industry, such as taxes, tariffs, duties, subsidies, and import and export restrictions on automotive products can influence industry profitability. In addition, such companies must comply with environmental laws and regulations, for which there may be severe consequences for non-compliance. While most of the major automotive manufacturers are large companies, certain others may be non-diversified in both product line and customer base and may be more vulnerable to certain events that may negatively impact the automotive industry.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG CEG DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of CEG’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CEG during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how CEG volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) CEG volatility; b) CEG performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to CEG. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of CEG volatility and CEG performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to CEG; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of CEG.

 

During periods of higher CEG volatility, the volatility of CEG may affect the Fund’s return as much as, or more than, the return of CEG. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CEG during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if CEG provided no return over a one-year period during which CEG experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if CEG’s return is flat. For instance, if CEG’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of CEG and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of CEG. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

CEG’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 43.74%. CEG’s annualized daily volatility rates were as follows:

 

2022       47.46%

2023       27.36%

2024       52.49%

 

Volatility for a shorter period of time may have been substantially higher.

 

CEG’s annualized performance for the five-year period ended December 31, 2024 was 76.28%. Historical volatility and performance are not indications of what CEG volatility and performance will be in the future. CEG’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for CEG is $352.00 on January 23, 2025 and the 52-week low stock price for CEG is $155.60, which occurred on August 5, 2024. CEG’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG CEG DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of CEG will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in CEG, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if CEG subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if CEG does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with CEG and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG CEG DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG CEG DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG CEG DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG CEG DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of CEG, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to CEG that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG CEG DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of CEG at the market close on the first trading day and the value of CEG at the time of purchase. If CEG gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CEG declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of CEG.

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with CEG. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that CEG value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the CEG. Under such circumstances, the market for CEG may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of CEG and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for CEG and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of CEG and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with CEG and may incur substantial losses. If there is a significant intra-day market event and/or CEG experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of CEG does not provide leveraged exposure to CEG and, as a result, if the Fund invests directly in common stock of CEG to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG CEG DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

In addition to the risks associated generally with operating companies, CEG faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of CEG common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of CEG’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. CEG is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Utilities Sector Risk. The Fund’s assets will be concentrated in the utilities sector, which means the Fund will be more affected by the performance of the utilities sector than a fund that is more diversified. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability.

 

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG DDOG DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of DDOG’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DDOG during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how DDOG volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) DDOG volatility; b) DDOG performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to DDOG. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of DDOG volatility and DDOG performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to DDOG; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of DDOG.

 

During periods of higher DDOG volatility, the volatility of DDOG may affect the Fund’s return as much as, or more than, the return of DDOG. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DDOG during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if DDOG provided no return over a one-year period during which DDOG experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if DDOG’s return is flat. For instance, if DDOG’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of DDOG and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of DDOG. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

DDOG’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 59.20%. DDOG’s annualized daily volatility rates were as follows:

 

2020       65.89%

2021       51.13%

2022       75.37%

2023       58.72%

Volatility for a shorter period of time may have been substantially higher.

 

DDOG’s annualized performance for the five-year period ended December 31, 2024 was 30.44%. Historical volatility and performance are not indications of what DDOG volatility and performance will be in the future. DDOG’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for DDOG is $170.08 on December 6, 2024 and the 52-week low stock price for DDOG is $81.63, which occurred on April 7, 2025. DDOG’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG DDOG DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of DDOG will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in DDOG, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if DDOG subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if DDOG does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with DDOG and may increase the volatility of the Fund.

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG DDOG DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG DDOG DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG DDOG DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG DDOG DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of DDOG, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to DDOG that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG DDOG DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of DDOG at the market close on the first trading day and the value of DDOG at the time of purchase. If DDOG gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if DDOG declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of DDOG.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG DDOG DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to DDOG and therefore achieve its daily leveraged investment objective. The Fund’s exposure to DDOG is impacted by DDOG’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to DDOG at the end of each day. The possibility of the Fund being materially over- or under-exposed to DDOG increases on days when DDOG is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) DDOG. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with DDOG. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to DDOG. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of DDOG. Any of these factors could decrease the correlation between the performance of the Fund and DDOG and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with DDOG. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that DDOG value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the DDOG. Under such circumstances, the market for DDOG may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of DDOG and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for DDOG and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of DDOG and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with DDOG and may incur substantial losses. If there is a significant intra-day market event and/or DDOG experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of DDOG does not provide leveraged exposure to DDOG and, as a result, if the Fund invests directly in common stock of DDOG to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG DDOG DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

Computer software companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer software companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of computer software companies depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

DDOG Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, DDOG faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of DDOG common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of DDOG’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. DDOG is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG WGS DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of WGS’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of WGS during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how WGS volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) WGS volatility; b) WGS performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to WGS. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of WGS volatility and WGS performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to WGS; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of WGS.

During periods of higher WGS volatility, the volatility of WGS may affect the Fund’s return as much as, or more than, the return of WGS. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of WGS during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if WGS provided no return over a one-year period during which WGS experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if WGS’s return is flat. For instance, if WGS’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of WGS and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of WGS. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

WGS’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 110.19%. WGS’s annualized daily volatility rates were as follows:

 

2020       30.47%

2021       81.65%

2022       108.35%

2023       121.31%

2024       127.16%

 

Volatility for a shorter period of time may have been substantially higher.

 

WGS’s annualized performance for the five-year period ended December 31, 2024 was -29.21%. Historical volatility and performance are not indications of what WGS volatility and performance will be in the future. WGS’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for WGS is $117.75 on April 29, 2025 and the 52-week low stock price for WGS is $25.32, which occurred on August 5, 2024. WGS’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG WGS DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of WGS will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in WGS, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if WGS subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if WGS does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with WGS and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG WGS DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG WGS DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG WGS DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG WGS DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of WGS, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to WGS that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG WGS DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of WGS at the market close on the first trading day and the value of WGS at the time of purchase. If WGS gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if WGS declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of WGS.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG WGS DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to WGS and therefore achieve its daily leveraged investment objective. The Fund’s exposure to WGS is impacted by WGS’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to WGS at the end of each day. The possibility of the Fund being materially over- or under-exposed to WGS increases on days when WGS is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) WGS. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with WGS. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to WGS. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of WGS. Any of these factors could decrease the correlation between the performance of the Fund and WGS and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with WGS. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that WGS value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the WGS. Under such circumstances, the market for WGS may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of WGS and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for WGS and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of WGS and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with WGS and may incur substantial losses. If there is a significant intra-day market event and/or WGS experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of WGS does not provide leveraged exposure to WGS and, as a result, if the Fund invests directly in common stock of WGS to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG WGS DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG WGS DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

WGS Investing Risk. . Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, WGS faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of WGS common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of WGS’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. WGS is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Healthcare Sector Risk. The Fund’s assets will be concentrated in the healthcare sector, which means the Fund will be more affected by the performance of the healthcare sector than a fund that is more diversified. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG DNA DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of DNA’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DNA during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how DNA volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) DNA volatility; b) DNA performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to DNA. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of DNA volatility and DNA performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to DNA; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of DNA.

 

During periods of higher DNA volatility, the volatility of DNA may affect the Fund’s return as much as, or more than, the return of DNA. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DNA during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if DNA provided no return over a one-year period during which DNA experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if DNA’s return is flat. For instance, if DNA’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of DNA and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of DNA. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

DNA’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 94.42%. DNA’s annualized daily volatility rates were as follows:

 

2021       71.25%

2022       104.15%

2023       89.32%

2024       103.28%

 

Volatility for a shorter period of time may have been substantially higher.

 

DNA’s annualized performance for the five-year period ended December 31, 2024 was -63.36%. Historical volatility and performance are not indications of what DNA volatility and performance will be in the future. DNA’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for DNA is $16.85 on February 6, 2025 and the 52-week low stock price for DNA is $5.00, which occurred on April 4, 2025. DNA’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG DNA DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of DNA will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in DNA, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if DNA subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if DNA does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with DNA and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG DNA DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG DNA DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG DNA DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG DNA DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of DNA, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to DNA that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG DNA DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of DNA at the market close on the first trading day and the value of DNA at the time of purchase. If DNA gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if DNA declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of DNA.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG DNA DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to DNA and therefore achieve its daily leveraged investment objective. The Fund’s exposure to DNA is impacted by DNA’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to DNA at the end of each day. The possibility of the Fund being materially over- or under-exposed to DNA increases on days when DNA is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) DNA. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with DNA. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to DNA. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of DNA. Any of these factors could decrease the correlation between the performance of the Fund and DNA and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Ginko Bioworks Holdings, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Ginko Bioworks Holdings, Inc. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, DNA is assigned to the healthcare sector and the biotechnology industry.

T-REX 2X LONG DNA DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG DNA DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with DNA. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that DNA value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the DNA. Under such circumstances, the market for DNA may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of DNA and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for DNA and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of DNA and correlated derivative instruments.

Prospectus [Line Items]  
Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with DNA and may incur substantial losses. If there is a significant intra-day market event and/or DNA experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of DNA does not provide leveraged exposure to DNA and, as a result, if the Fund invests directly in common stock of DNA to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG DNA DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG DNA DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Healthcare Sector Risk. The Fund’s assets will be concentrated in the healthcare sector, which means the Fund will be more affected by the performance of the healthcare sector than a fund that is more diversified. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

DNA Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, DNA faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of DNA common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of DNA’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. DNA is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG KTOS DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of KTOS’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of KTOS during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how KTOS volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) KTOS volatility; b) KTOS performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to KTOS. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of KTOS volatility and KTOS performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to KTOS; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of KTOS.

 

During periods of higher KTOS volatility, the volatility of KTOS may affect the Fund’s return as much as, or more than, the return of KTOS. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of KTOS during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if KTOS provided no return over a one-year period during which KTOS experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if KTOS’s return is flat. For instance, if KTOS’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of KTOS and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of KTOS. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

KTOS’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 49.81%. KTOS’s annualized daily volatility rates were as follows:

 

2020       64.06%

2021       43.06%

2022       54.70%

2023       41.86%

2024       41.05%

 

Volatility for a shorter period of time may have been substantially higher.

 

KTOS’s annualized performance for the five-year period ended December 31, 2024 was 7.92%. Historical volatility and performance are not indications of what KTOS volatility and performance will be in the future. KTOS’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for KTOS is $59.12 on July 17, 2025 and the 52-week low stock price for KTOS is $17.91, which occurred on August 8, 2024. KTOS’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG KTOS DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of KTOS will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in KTOS, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if KTOS subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if KTOS does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with KTOS and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG KTOS DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG KTOS DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG KTOS DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG KTOS DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of KTOS, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to KTOS that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG KTOS DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of KTOS at the market close on the first trading day and the value of KTOS at the time of purchase. If KTOS gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if KTOS declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of KTOS.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

The Fund’s exposure to KTOS is impacted by KTOS’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to KTOS at the end of each day. The possibility of the Fund being materially over- or under-exposed to KTOS increases on days when KTOS is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) KTOS. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with KTOS. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to KTOS. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of KTOS. Any of these factors could decrease the correlation between the performance of the Fund and KTOS and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

T-REX 2X LONG KTOS DAILY TARGET ETF | Industrials Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Industrials Sector Risk. The Fund’s assets will be concentrated in the industrials sector, which means the Fund will be more affected by the performance of the industrials sector than a fund that is more diversified. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG KTOS DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with KTOS. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that KTOS value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the KTOS. Under such circumstances, the market for KTOS may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of KTOS and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for KTOS and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of KTOS and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with KTOS and may incur substantial losses. If there is a significant intra-day market event and/or KTOS experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of KTOS does not provide leveraged exposure to KTOS and, as a result, if the Fund invests directly in common stock of KTOS to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG KTOS DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG KTOS DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

KTOS Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, KTOS faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of KTOS common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of KTOS’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. KTOS is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG OKLO DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of OKLO’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of OKLO during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how OKLO volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) OKLO volatility; b) OKLO performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to OKLO. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of OKLO volatility and OKLO performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to OKLO; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of OKLO.

 

During periods of higher OKLO volatility, the volatility of OKLO may affect the Fund’s return as much as, or more than, the return of OKLO. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of OKLO during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if OKLO provided no return over a one-year period during which OKLO experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if OKLO’s return is flat. For instance, if OKLO’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of OKLO and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of OKLO. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

OKLO’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 71.05%. OKLO’s annualized daily volatility rates were as follows:

 

2021       8.89%

2022       4.40%

2023       5.91%

2024       130.00%

 

Volatility for a shorter period of time may have been substantially higher.

 

OKLO’s annualized performance for the five-year period ended December 31, 2024 was 24.09%. Historical volatility and performance are not indications of what OKLO volatility and performance will be in the future. OKLO’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for OKLO is $73.55 on June 16, 2025 and the 52-week low stock price for OKLO is $5.35, which occurred on September 9, 2024. OKLO’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG OKLO DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of OKLO will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in OKLO, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if OKLO subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if OKLO does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with OKLO and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG OKLO DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of OKLO, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to OKLO that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG OKLO DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of OKLO at the market close on the first trading day and the value of OKLO at the time of purchase. If OKLO gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if OKLO declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of OKLO.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG OKLO DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to OKLO and therefore achieve its daily leveraged investment objective. The Fund’s exposure to OKLO is impacted by OKLO’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to OKLO at the end of each day. The possibility of the Fund being materially over- or under-exposed to OKLO increases on days when OKLO is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) OKLO. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with OKLO. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to OKLO. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of OKLO. Any of these factors could decrease the correlation between the performance of the Fund and OKLO and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Oklo Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Oklo Inc. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, OKLO is assigned to the utilities sector and the utilities – regulated electric industry.

T-REX 2X LONG OKLO DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG OKLO DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with OKLO. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that OKLO value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the OKLO. Under such circumstances, the market for OKLO may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of OKLO and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for OKLO and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of OKLO and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with OKLO and may incur substantial losses. If there is a significant intra-day market event and/or OKLO experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Risk [Text Block]

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of OKLO does not provide leveraged exposure to OKLO and, as a result, if the Fund invests directly in common stock of OKLO to a greater extent, the Fund may not achieve its 200% daily investment objective.

T-REX 2X LONG OKLO DAILY TARGET ETF | Cash Transaction Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG OKLO DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG OKLO DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

T-REX 2X LONG OKLO DAILY TARGET ETF | Utilities Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Utilities Sector Risk. The Fund’s assets will be concentrated in the utilities sector, which means the Fund will be more affected by the performance of the utilities sector than a fund that is more diversified. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability.

 

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes.

OKLO Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, OKLO faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of OKLO common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of OKLO’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. OKLO is a highly dynamic company, and its operations, including its products and services, may change.

T-REX 2X LONG OKLO DAILY TARGET ETF | Nuclear Energy Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Nuclear Energy Companies Risk. Nuclear energy companies may face considerable risk as a result of incidents and accidents, breaches of security, ill-intentioned acts of terrorism, natural disasters (such as floods or earthquakes), equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials. Such events could have serious consequences, especially in case of radioactive contamination and irradiation of the environment, for the general population, as well as a material, negative impact on the Fund’s portfolio companies and thus the Fund’s financial situation. In addition, nuclear energy companies are subject to competitive risk associated with the prices of other energy sources, such as natural gas and oil. Consumers of nuclear energy may have the ability to switch between nuclear energy and other energy sources and, as a result, during periods when competing energy sources are less expensive, the revenues of nuclear energy companies may decline with a corresponding impact on earnings.

 

Nuclear activity is also subject to particularly detailed and restrictive regulations, with a scheme for the monitoring and periodic re-examination of operating authorization, which primarily takes into account nuclear safety, environmental and public health protection, and also national security considerations (terrorist threats in particular). These regulations and any future regulations may be subject to significant tightening by national and international authorities. This could result in increased operating costs, which would have a negative impact on the Fund’s portfolio companies and may cause operating businesses related to nuclear energy to become unprofitable or impractical to operate.

 

Uranium prices are subject to fluctuation. The price of uranium may be affected by numerous factors beyond the Fund’s control. Such factors include the demand for nuclear power, political and economic conditions in uranium producing and consuming countries, uranium supply from secondary sources and uranium production levels and costs of production. In addition, the prices of crude oil, natural gas and electricity produced from traditional hydro power and possibly other undiscovered energy sources could potentially have a negative impact on the competitiveness of nuclear energy companies in which the Fund invests.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG QUBT DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of QUBT’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of QUBT during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how QUBT volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) QUBT volatility; b) QUBT performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to QUBT. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of QUBT volatility and QUBT performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to QUBT; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of QUBT.

 

During periods of higher QUBT volatility, the volatility of QUBT may affect the Fund’s return as much as, or more than, the return of QUBT. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of QUBT during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if QUBT provided no return over a one-year period during which QUBT experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if QUBT’s return is flat. For instance, if QUBT’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of QUBT and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of QUBT. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

QUBT’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 148.16%. QUBT’s annualized daily volatility rates were as follows:

 

2020       199.94%

2021       110.96%

2022       110.52%

2023       87.57%

2024       197.86%

 

Volatility for a shorter period of time may have been substantially higher.

 

QUBT’s annualized performance for the five-year period ended December 31, 2024 was 40.66%. Historical volatility and performance are not indications of what QUBT volatility and performance will be in the future. QUBT’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for QUBT is $27.15 on December 18, 2024 and the 52-week low stock price for QUBT is $0.53, which occurred on August 5, 2024. QUBT’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG QUBT DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of QUBT will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in QUBT, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if QUBT subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if QUBT does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with QUBT and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG QUBT DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG QUBT DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG QUBT DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of QUBT, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to QUBT that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG QUBT DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of QUBT at the market close on the first trading day and the value of QUBT at the time of purchase. If QUBT gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if QUBT declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of QUBT.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG QUBT DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to QUBT and therefore achieve its daily leveraged investment objective. The Fund’s exposure to QUBT is impacted by QUBT’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to QUBT at the end of each day. The possibility of the Fund being materially over- or under-exposed to QUBT increases on days when QUBT is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) QUBT. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with QUBT. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to QUBT. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of QUBT. Any of these factors could decrease the correlation between the performance of the Fund and QUBT and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries.

T-REX 2X LONG QUBT DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with QUBT. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that QUBT value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the QUBT. Under such circumstances, the market for QUBT may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of QUBT and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for QUBT and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of QUBT and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with QUBT and may incur substantial losses. If there is a significant intra-day market event and/or QUBT experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of QUBT does not provide leveraged exposure to QUBT and, as a result, if the Fund invests directly in common stock of QUBT to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG QUBT DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds.

Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

QUBT Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, QUBT faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of QUBT common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of QUBT’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. QUBT is a highly dynamic company, and its operations, including its products and services, may change.

Computer Technology Company Risk. The performance of QUBT, and consequently the Fund’s performance, is subject to the risks of the technology industry. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation, and competition, both domestically and internationally, including competition from competitors with lower production costs. In addition, many information technology companies have limited product lines, markets, financial resources or personnel. The prices of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile and less liquid than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG RXRX DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of RXRX’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of RXRX during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how RXRX volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) RXRX volatility; b) RXRX performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to RXRX. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of RXRX volatility and RXRX performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to RXRX; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of RXRX.

 

During periods of higher RXRX volatility, the volatility of RXRX may affect the Fund’s return as much as, or more than, the return of RXRX. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of RXRX during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if RXRX provided no return over a one-year period during which RXRX experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if RXRX’s return is flat. For instance, if RXRX’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of RXRX and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of RXRX. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

RXRX’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 104.38%. RXRX’s annualized daily volatility rates were as follows:

 

2021       125.37%

2022       91.67%

2023       115.29%

Volatility for a shorter period of time may have been substantially higher.

 

RXRX’s annualized performance for the five-year period ended December 31, 2024 was -23.17%. Historical volatility and performance are not indications of what RXRX volatility and performance will be in the future. RXRX’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for RXRX is $12.36 on February 18, 2025 and the 52-week low stock price for RXRX is $3.79, which occurred on April 9, 2025. RXRX’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG RXRX DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of RXRX will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in RXRX, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if RXRX subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if RXRX does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with RXRX and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG RXRX DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG RXRX DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG RXRX DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

Risk [Text Block]

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG RXRX DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of RXRX, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

T-REX 2X LONG RXRX DAILY TARGET ETF | Rebalancing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to RXRX that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG RXRX DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of RXRX at the market close on the first trading day and the value of RXRX at the time of purchase. If RXRX gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if RXRX declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of RXRX.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG RXRX DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to RXRX and therefore achieve its daily leveraged investment objective. The Fund’s exposure to RXRX is impacted by RXRX’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to RXRX at the end of each day. The possibility of the Fund being materially over- or under-exposed to RXRX increases on days when RXRX is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) RXRX. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with RXRX. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to RXRX. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of RXRX. Any of these factors could decrease the correlation between the performance of the Fund and RXRX and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Recursion Pharmaceuticals, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Recursion Pharmaceuticals, Inc. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, RXRX is assigned to the healthcare sector and the biotechnology industry.

T-REX 2X LONG RXRX DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG RXRX DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with RXRX. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that RXRX value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the RXRX. Under such circumstances, the market for RXRX may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of RXRX and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for RXRX and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of RXRX and correlated derivative instruments.

Prospectus [Line Items]  
Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with RXRX and may incur substantial losses. If there is a significant intra-day market event and/or RXRX experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Risk [Text Block]

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of RXRX does not provide leveraged exposure to RXRX and, as a result, if the Fund invests directly in common stock of RXRX to a greater extent, the Fund may not achieve its 200% daily investment objective.

T-REX 2X LONG RXRX DAILY TARGET ETF | Cash Transaction Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG RXRX DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG RXRX DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Healthcare Sector Risk. The Fund’s assets will be concentrated in the healthcare sector, which means the Fund will be more affected by the performance of the healthcare sector than a fund that is more diversified. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

RXRX Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, RXRX faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of RXRX common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of RXRX’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price.

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG TEM DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of TEM’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of TEM during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how TEM volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) TEM volatility; b) TEM performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to TEM. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of TEM volatility and TEM performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to TEM; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of TEM.

 

During periods of higher TEM volatility, the volatility of TEM may affect the Fund’s return as much as, or more than, the return of TEM. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of TEM during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if TEM provided no return over a one-year period during which TEM experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if TEM’s return is flat. For instance, if TEM’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of TEM and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of TEM. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

TEM’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 123.20%. TEM’s annualized daily volatility rates were as follows:

 

2024       123.20%

 

Volatility for a shorter period of time may have been substantially higher.

 

TEM’s annualized performance for the five-year period ended December 31, 2024 was -15.33%. Historical volatility and performance are not indications of what TEM volatility and performance will be in the future. TEM’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for TEM is $91.45 on February 14, 2025 and the 52-week low stock price for TEM is $31.36, which occurred on January 13, 2025. TEM’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG TEM DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of TEM will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in TEM, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if TEM subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if TEM does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with TEM and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG TEM DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG TEM DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG TEM DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG TEM DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of TEM, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to TEM that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG TEM DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of TEM at the market close on the first trading day and the value of TEM at the time of purchase. If TEM gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if TEM declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of TEM.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG TEM DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to TEM and therefore achieve its daily leveraged investment objective. The Fund’s exposure to TEM is impacted by TEM’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to TEM at the end of each day. The possibility of the Fund being materially over- or under-exposed to TEM increases on days when TEM is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) TEM. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with TEM. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to TEM. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of TEM. Any of these factors could decrease the correlation between the performance of the Fund and TEM and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries.

T-REX 2X LONG TEM DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG TEM DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with TEM. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that TEM value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the TEM. Under such circumstances, the market for TEM may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of TEM and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for TEM and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of TEM and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with TEM and may incur substantial losses. If there is a significant intra-day market event and/or TEM experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of TEM does not provide leveraged exposure to TEM and, as a result, if the Fund invests directly in common stock of TEM to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG TEM DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

The Fund’s assets will be concentrated in the healthcare sector, which means the Fund will be more affected by the performance of the healthcare sector than a fund that is more diversified. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

TEM Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, TEM faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of TEM common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of TEM’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. TEM is a highly dynamic company, and its operations, including its products and services, may change.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG TTD DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of TTD’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of TTD during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how TTD volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) TTD volatility; b) TTD performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to TTD. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of TTD volatility and TTD performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to TTD; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of TTD.

 

During periods of higher TTD volatility, the volatility of TTD may affect the Fund’s return as much as, or more than, the return of TTD. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of TTD during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if TTD provided no return over a one-year period during which TTD experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if TTD’s return is flat. For instance, if TTD’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of TTD and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of TTD. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

TTD’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 68.47%. TTD’s annualized daily volatility rates were as follows:

 

2020       76.83%

2021       70.43%

2022       87.59%

2023       56.00%

2024       42.17%

 

Volatility for a shorter period of time may have been substantially higher.

 

TTD’s annualized performance for the five-year period ended December 31, 2024 was 35.20%. Historical volatility and performance are not indications of what TTD volatility and performance will be in the future. TTD’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for TTD is $141.53 on December 4, 2024 and the 52-week low stock price for TTD is $42.96, which occurred on April 7, 2025. TTD’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG TTD DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of TTD will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in TTD, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if TTD subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if TTD does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with TTD and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG TTD DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG TTD DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG TTD DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG TTD DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of TTD, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to TTD that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG TTD DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of TTD at the market close on the first trading day and the value of TTD at the time of purchase. If TTD gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if TTD declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of TTD.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG TTD DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to TTD and therefore achieve its daily leveraged investment objective. The Fund’s exposure to TTD is impacted by TTD’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to TTD at the end of each day. The possibility of the Fund being materially over- or under-exposed to TTD increases on days when TTD is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) TTD. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with TTD. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to TTD. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of TTD. Any of these factors could decrease the correlation between the performance of the Fund and TTD and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

T-REX 2X LONG TTD DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with TTD. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that TTD value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the TTD. Under such circumstances, the market for TTD may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of TTD and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for TTD and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of TTD and correlated derivative instruments.

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with TTD and may incur substantial losses. If there is a significant intra-day market event and/or TTD experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of TTD does not provide leveraged exposure to TTD and, as a result, if the Fund invests directly in common stock of TTD to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG TTD DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG TTD DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

Computer Software Industry Risk. Computer software companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer software companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of computer software companies depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

TTD Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, TTD faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of TTD common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of TTD’S common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. TTD is a highly dynamic company, and its operations, including its products and services, may change.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG UPXI DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of UPXI’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of UPXI during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how UPXI volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) UPXI volatility; b) UPXI performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to UPXI. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of UPXI volatility and UPXI performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to UPXI; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of UPXI.

 

During periods of higher UPXI volatility, the volatility of UPXI may affect the Fund’s return as much as, or more than, the return of UPXI. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of UPXI during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if UPXI provided no return over a one-year period during which UPXI experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if UPXI’s return is flat. For instance, if UPXI’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of UPXI and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of UPXI. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

UPXI’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 133.79%. UPXI’s annualized daily volatility rates were as follows:

 

2021       126.21%

2022       72.59%

2023       76.11%

2024       209.11%

 

Volatility for a shorter period of time may have been substantially higher.

 

UPXI’s annualized performance for the five-year period ended December 31, 2024 was -61.32%. Historical volatility and performance are not indications of what UPXI volatility and performance will be in the future. UPXI’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for UPXI is $22.57 on April 25, 2025 and the 52-week low stock price for UPXI is $1.90, which occurred on April 9, 2025. UPXI’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG UPXI DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of UPXI will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in UPXI, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if UPXI subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if UPXI does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with UPXI and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG UPXI DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG UPXI DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG UPXI DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG UPXI DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of UPXI, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to UPXI that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG UPXI DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of UPXI at the market close on the first trading day and the value of UPXI at the time of purchase. If UPXI gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if UPXI declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of UPXI.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG UPXI DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to UPXI and therefore achieve its daily leveraged investment objective. The Fund’s exposure to UPXI is impacted by UPXI’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to UPXI at the end of each day. The possibility of the Fund being materially over- or under-exposed to UPXI increases on days when UPXI is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) UPXI. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with UPXI. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to UPXI. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of UPXI. Any of these factors could decrease the correlation between the performance of the Fund and UPXI and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

T-REX 2X LONG UPXI DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with UPXI. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that UPXI value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the UPXI. Under such circumstances, the market for UPXI may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of UPXI and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for UPXI and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of UPXI and correlated derivative instruments.

An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with UPXI and may incur substantial losses. If there is a significant intra-day market event and/or UPXI experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of UPXI does not provide leveraged exposure to UPXI and, as a result, if the Fund invests directly in common stock of UPXI to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG UPXI DAILY TARGET ETF | Tax Risk [Member]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG UPXI DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

UPXI Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, UPXI faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of UPXI common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of UPXI’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. UPXI is a highly dynamic company, and its operations, including its products and services, may change.

Communication Services Sector Risk. The communication services industry is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the communication services companies. The communication services industry can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid product obsolescence and research and development of new products. Technological innovations may make the products and services of communication services companies obsolete. Other risks include substantial capital requirements and uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Risk [Text Block]

Internet & Direct Marketing Retail Risk. Companies that operate via the internet or direct marketing (e.g., online consumer services, online retail, travel) segments are subject to fluctuating consumer demand. Unlike traditional brick and mortar retailers, online marketplaces and retailers must assume shipping costs or pass such costs to consumers. Consumer access to price information for the same or similar products may cause companies that operate in the online marketplace, retail and travel segments to reduce profit margins in order to compete. Due to the nature of their business models, companies that operate in the online marketplace, retail, and travel segments may also be subject to heightened cybersecurity risk, including the risk of theft or damage to vital hardware, software, and information systems. The loss or public dissemination of sensitive customer information or other proprietary data may negatively affect the financial performance of such companies to a greater extent than traditional brick and mortar retailers. As a result of such companies being web-based and the fact that they process, store, and transmit large amounts of data, including personal information, for their customers, failure to prevent or mitigate data loss or other security breaches, including breaches of vendors technology and systems, could expose companies that operate via the internet or direct marketing retail to a risk of loss or misuse of such information, adversely affect their operating results, result in litigation or potential liability, and otherwise harm their businesses.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG UPST DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of UPST’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of UPST during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how UPST volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) UPST volatility; b) UPST performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to UPST. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of UPST volatility and UPST performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to UPST; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of UPST.

 

During periods of higher UPST volatility, the volatility of UPST may affect the Fund’s return as much as, or more than, the return of UPST. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of UPST during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if UPST provided no return over a one-year period during which UPST experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if UPST’s return is flat. For instance, if UPST’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of UPST and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of UPST. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

UPST’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 125.94%. UPST’s annualized daily volatility rates were as follows:

 

2020       274.50%

2021       142.13%

2022       130.60%

2023       117.06%

2024       96.99%

 

Volatility for a shorter period of time may have been substantially higher.

 

UPST’s annualized performance for the five-year period ended December 31, 2024 was 32.03%. Historical volatility and performance are not indications of what UPST volatility and performance will be in the future. UPST’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for UPST is $96.43 on February 13, 2025 and the 52-week low stock price for UPST is $20.60, which occurred on August 5, 2024. UPST’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG UPST DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of UPST will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in UPST, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if UPST subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if UPST does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with UPST and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG UPST DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG UPST DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG UPST DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG UPST DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of UPST, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to UPST that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG UPST DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of UPST at the market close on the first trading day and the value of UPST at the time of purchase. If UPST gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if UPST declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of UPST.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG UPST DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to UPST and therefore achieve its daily leveraged investment objective. The Fund’s exposure to UPST is impacted by UPST’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to UPST at the end of each day. The possibility of the Fund being materially over- or under-exposed to UPST increases on days when UPST is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) UPST. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with UPST. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to UPST. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of UPST. Any of these factors could decrease the correlation between the performance of the Fund and UPST and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

The Fund will be concentrated in the industry to which Upstart Holdings, Inc.is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Upstart Holdings, Inc.is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, UPST is assigned to the financial services sector and the credit services industry.

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Money market funds may be subject to credit risk with respect to the debt instruments in which they invest. Depository accounts may be subject to credit risk with respect to the financial institution in which the depository account is held. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments may lose money.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG UPST DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with UPST. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that UPST value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the UPST. Under such circumstances, the market for UPST may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of UPST and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for UPST and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of UPST and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with UPST and may incur substantial losses. If there is a significant intra-day market event and/or UPST experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of UPST does not provide leveraged exposure to UPST and, as a result, if the Fund invests directly in common stock of UPST to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG UPST DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG UPST DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange.

UPST Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, UPST faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of UPST common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of UPST’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. UPST is a highly dynamic company, and its operations, including its products and services, may change.

Financials Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITs). Declining real estate values could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG SOUN DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of SOUN’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SOUN during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how SOUN volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) SOUN volatility; b) SOUN performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to SOUN. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of SOUN volatility and SOUN performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to SOUN; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of SOUN.

 

During periods of higher SOUN volatility, the volatility of SOUN may affect the Fund’s return as much as, or more than, the return of SOUN. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SOUN during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if SOUN provided no return over a one-year period during which SOUN experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if SOUN’s return is flat. For instance, if SOUN’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of SOUN and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of SOUN. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

SOUN’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 154.49%. SOUN’s annualized daily volatility rates were as follows:

 

2022       190.71%

2023       140.35%

2024       139.85%

 

Volatility for a shorter period of time may have been substantially higher.

 

SOUN’s annualized performance for the five-year period ended December 31, 2024 was 43.77%. Historical volatility and performance are not indications of what SOUN volatility and performance will be in the future. SOUN’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for SOUN is $24.98 on December 26, 2024 and the 52-week low stock price for SOUN is $3.94, which occurred on August 5, 2024. SOUN’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG SOUN DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of SOUN will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in SOUN, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if SOUN subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if SOUN does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SOUN and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG SOUN DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG SOUN DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG SOUN DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG SOUN DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of SOUN, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to SOUN that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG SOUN DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of SOUN at the market close on the first trading day and the value of SOUN at the time of purchase. If SOUN gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if SOUN declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of SOUN.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to SOUN and therefore achieve its daily leveraged investment objective. The Fund’s exposure to SOUN is impacted by SOUN’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to SOUN at the end of each day. The possibility of the Fund being materially over- or under-exposed to SOUN increases on days when SOUN is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) SOUN. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with SOUN. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to SOUN. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of SOUN. Any of these factors could decrease the correlation between the performance of the Fund and SOUN and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which SoundHound AI, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which SoundHound AI, Inc. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries.

T-REX 2X LONG SOUN DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG SOUN DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with SOUN. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that SOUN value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in SOUN. Under such circumstances, the market for SOUN may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of SOUN and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for SOUN and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of SOUN and correlated derivative instruments.

Prospectus [Line Items]  
Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with SOUN and may incur substantial losses. If there is a significant intra-day market event and/or SOUN experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Risk [Text Block]

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of SOUN does not provide leveraged exposure to SOUN and, as a result, if the Fund invests directly in common stock of SOUN to a greater extent, the Fund may not achieve its 200% daily investment objective.

T-REX 2X LONG SOUN DAILY TARGET ETF | Cash Transaction Risk [Member]  
Prospectus [Line Items]

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG SOUN DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
T-REX 2X LONG SOUN DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

Computer Software Industry Risk. Computer software companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer software companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of computer software companies depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

SOUN Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, SOUN faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of SOUN common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of SOUN’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. SOUN is a highly dynamic company, and its operations, including its products and services, may change.

Prospectus [Line Items]  
Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG SMLR DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of SMLR’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SMLR during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how SMLR volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) SMLR volatility; b) SMLR performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to SMLR. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of SMLR volatility and SMLR performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to SMLR; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of SMLR.

 

During periods of higher SMLR volatility, the volatility of SMLR may affect the Fund’s return as much as, or more than, the return of SMLR. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SMLR during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if SMLR provided no return over a one-year period during which SMLR experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if SMLR’s return is flat. For instance, if SMLR’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of SMLR and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of SMLR. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

SMLR’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 72.36%. SMLR’s annualized daily volatility rates were as follows:

 

2020       57.24%

2021       52.29%

2022       76.67%

2023       69.07%

2024       97.71%

 

Volatility for a shorter period of time may have been substantially higher.

 

SMLR’s annualized performance for the five-year period ended December 31, 2024 was 2.38%. Historical volatility and performance are not indications of what SMLR volatility and performance will be in the future. SMLR’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for SMLR is $81.56 on December 17, 2024 and the 52-week low stock price for SMLR is $21.77, which occurred on September 23, 2024. SMLR’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG SMLR DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of SMLR will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in SMLR, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if SMLR subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if SMLR does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SMLR and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG SMLR DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG SMLR DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of SMLR, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Risk [Text Block]

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to SMLR that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG SMLR DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of SMLR at the market close on the first trading day and the value of SMLR at the time of purchase. If SMLR gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if SMLR declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of SMLR.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG SMLR DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to SMLR and therefore achieve its daily leveraged investment objective. The Fund’s exposure to SMLR is impacted by SMLR’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to SMLR at the end of each day. The possibility of the Fund being materially over- or under-exposed to SMLR increases on days when SMLR is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) SMLR. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with SMLR. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to SMLR. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of SMLR. Any of these factors could decrease the correlation between the performance of the Fund and SMLR and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Semler Scientific, Inc.is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Semler Scientific, Inc.is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, SMLR is assigned to the healthcare sector and the medical devices industry.

T-REX 2X LONG SMLR DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Large-Capitalization Company Risk. Large-capitalization companies typically have significant financial resources, extensive product lines and broad markets for their goods and/or services. However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG SMLR DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with SMLR. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that SMLR value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the SMLR. Under such circumstances, the market for SMLR may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of SMLR and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for SMLR and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of SMLR and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with SMLR and may incur substantial losses. If there is a significant intra-day market event and/or SMLR experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of SMLR does not provide leveraged exposure to SMLR and, as a result, if the Fund invests directly in common stock of SMLR to a greater extent, the Fund may not achieve its 200% daily investment objective.

T-REX 2X LONG SMLR DAILY TARGET ETF | Cash Transaction Risk [Member]

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG SMLR DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

T-REX 2X LONG SMLR DAILY TARGET ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Healthcare Sector Risk. The Fund’s assets will be concentrated in the healthcare sector, which means the Fund will be more affected by the performance of the healthcare sector than a fund that is more diversified. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

SMLR Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, SMLR faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of SMLR common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of SMLR’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. SMLR is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG GLXY DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of GLXY’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of GLXY during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how GLXY volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) GLXY volatility; b) GLXY performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to GLXY. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of GLXY volatility and GLXY performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to GLXY; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of GLXY.

 

During periods of higher GLXY volatility, the volatility of GLXY may affect the Fund’s return as much as, or more than, the return of GLXY. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of GLXY during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if GLXY provided no return over a one-year period during which GLXY experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if GLXY’s return is flat. For instance, if GLXY’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of GLXY and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of GLXY. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

GLXY’s annualized historical daily volatility rate for the five-year period ended December 31, 2024 was 105.95%. GLXY’s annualized daily volatility rates were as follows:

 

2020       119.89%

2021       121.34%

2022       114.88%

2023       79.78%

2024       85.30%

 

Volatility for a shorter period of time may have been substantially higher.

 

GLXY’s annualized performance for the five-year period ended December 31, 2024 was 84.20%. Historical volatility and performance are not indications of what GLXY volatility and performance will be in the future. GLXY’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for GLXY is $26.60 on May 19, 2025 and the 52-week low stock price for GLXY is $6.89, which occurred on August 5, 2024. GLXY’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG GLXY DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of GLXY will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in GLXY, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if GLXY subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if GLXY does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with GLXY and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG GLXY DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG GLXY DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

Risk [Text Block]

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG GLXY DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of GLXY, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to GLXY that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG GLXY DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of GLXY at the market close on the first trading day and the value of GLXY at the time of purchase. If GLXY gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if GLXY declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of GLXY.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG GLXY DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to GLXY and therefore achieve its daily leveraged investment objective. The Fund’s exposure to GLXY is impacted by GLXY’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to GLXY at the end of each day. The possibility of the Fund being materially over- or under-exposed to GLXY increases on days when GLXY is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) GLXY. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with GLXY. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to GLXY. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of GLXY. Any of these factors could decrease the correlation between the performance of the Fund and GLXY and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

The Fund will be concentrated in the industry to which Galaxy Digital Holdings Ltd.is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Galaxy Digital Holdings Ltd.is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, GLXY is assigned to the financial services sector and the capital markets industry.

T-REX 2X LONG GLXY DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG GLXY DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with GLXY. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that GLXY value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the GLXY. Under such circumstances, the market for GLXY may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of GLXY and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for GLXY and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of GLXY and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with GLXY and may incur substantial losses. If there is a significant intra-day market event and/or GLXY experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of GLXY does not provide leveraged exposure to GLXY and, as a result, if the Fund invests directly in common stock of GLXY to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG GLXY DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Financials Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITs). Declining real estate values could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

GLXY Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, GLXY faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of GLXY common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of GLXY’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. GLXY is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.

T-REX 2X LONG DUOL DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Effects of Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from 200% of DUOL’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are leveraged and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DUOL during the shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how DUOL volatility and its return could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) DUOL volatility; b) DUOL performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) dividends or interest paid with respect to DUOL. The chart below illustrates the impact of two principal factors – volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of DUOL volatility and DUOL performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to DUOL; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher volatility, compounding will cause results for periods longer than a trading day to vary from 200% of the performance of DUOL.

 

During periods of higher DUOL volatility, the volatility of DUOL may affect the Fund’s return as much as, or more than, the return of DUOL. The effects of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of DUOL during a shareholder’s holding period of an investment in the Fund.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if DUOL provided no return over a one-year period during which DUOL experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if DUOL’s return is flat. For instance, if DUOL’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of DUOL and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of DUOL. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

Volatility for a shorter period of time may have been substantially higher.

 

DUOL’s annualized performance for the five-year period ended December 31, 2024 was 40.06%. Historical volatility and performance are not indications of what DUOL volatility and performance will be in the future. DUOL’s stock price may be more volatile, and may fluctuate more than the market. By way of example, currently, the 52-week high stock price for DUOL is $544.93 on May 14, 2025 and the 52-week low stock price for DUOL is $145.05, which occurred on August 5, 2024. DUOL’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG DUOL DAILY TARGET ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of DUOL will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in DUOL, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event of a security decline of more than 50%. This would result in a total loss of a shareholder’s investment in one day even if DUOL subsequently moves in the opposite direction and eliminates all or a portion of its earlier daily change. A total loss may occur in a single day even if DUOL does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with DUOL and may increase the volatility of the Fund.

 

To the extent that the instruments utilized by the Fund are thinly traded or have a limited market, the Fund may be unable to meet its investment objective due to a lack of available investments or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. As a result, the Fund’s shares could trade at a premium or discount to their net asset value and/or the bid-ask spread of the Fund’s shares could widen. Under such circumstances, the Fund may increase its transaction fee, change its investment objective by, for example, seeking to track an alternative security, reduce its leverage or close. In such circumstances, the Fund’s investment adviser will consult with counsel to the Trust and its Board of Trustees, and if determined to be necessary, the Fund will amend and/or supplement the prospectus as promptly as feasible under the circumstances to include appropriate disclosures.

T-REX 2X LONG DUOL DAILY TARGET ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. Investing in derivatives may be considered aggressive and may expose the Fund to greater risks, and may result in larger losses or small gains, than investing directly in the reference assets underlying those derivatives, which may prevent the Fund from achieving its investment objective.

 

The Fund expects to use swap agreements to achieve its investment objective. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other investments, including risk related to the market, leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty, liquidity, valuation, and legal restrictions. The performance of a derivative may not track the performance of its reference asset, including due to fees and other costs associated with it. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of the amount initially invested. As a result, the value of an investment in the Fund may change quickly and without warning. Additionally, any financing, borrowing or other costs associated with using derivatives may also have the effect of lowering the Fund’s return. Such costs may increase as interest rates rise.

T-REX 2X LONG DUOL DAILY TARGET ETF | Swap Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swap Agreements. Swap agreements are entered into with financial institutions for a specified period which may range from one day to more than one year. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a reference asset. Swap agreements are generally traded over-the-counter, and therefore, may not receive as much regulatory protection as exchange-traded instruments, which may expose investors to significant losses.

 

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivatives portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy and the Fund may not achieve its investment objective. To the extent that the Fund exceeds the level of value at risk for an extended period, the Fund may amend and/or supplement its prospectus as promptly as feasible under the particular circumstances to include appropriate adjustments to its investment strategy and if necessary, the Fund’s name.

T-REX 2X LONG DUOL DAILY TARGET ETF | Call Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Options. The use of call options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, is actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which is affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, and the time remaining until the expiration of the option contract and economic events. The values of the options contracts in which the Fund invests are substantially influenced by the value of the underlying instrument. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the reference asset, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund may enter into new options contracts, a practice referred to as rolling.

FLEX Options. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the reference asset. Factors that may influence the value of the FLEX Options, other than gains or losses in the reference asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the reference asset. FLEX Options are listed on an exchange; however, it is not guaranteed that a liquid secondary trading market will exist. In the event that trading in the FLEX Options is limited or absent, the value of the FLEX Options may decrease.

T-REX 2X LONG DUOL DAILY TARGET ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty or its affiliate becomes insolvent, bankrupt or defaults on its payment obligations to the Fund, the value of an investment held by the Fund may decline. Additionally, if any collateral posted by the counterparty for the benefit of the Fund is insufficient or there are delays in the Fund’s ability to access such collateral, the Fund may not be able to achieve its leveraged investment objective.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective. The risk of a limited number of counterparties may be, and historically has been, particularly accentuated during times of significant market volatility. During times of significant market volatility, the costs to enter into the swaps that the Fund utilizes may increase significantly, which may negatively impact the Fund’s returns. While the objective of the Fund is to seek daily investment results, before fees and expenses, of 200% of the daily performance of DUOL, it is important for investors to understand that significant increases in the costs of entering into the swaps may negatively impact investment results after fees and expenses.

Risk [Text Block]

Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to DUOL that is significantly greater or significantly less than its stated multiple. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

T-REX 2X LONG DUOL DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Intra-Day Investment Risk. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of DUOL at the market close on the first trading day and the value of DUOL at the time of purchase. If DUOL gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if DUOL declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple of DUOL.

 

If there is a significant intra-day market event and/or the securities experience a significant change in value, the Fund may not meet its investment objective, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of shares (“Shares”) prior to the close of trading on the Exchange and incur significant losses.

T-REX 2X LONG DUOL DAILY TARGET ETF | Daily Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to DUOL and therefore achieve its daily leveraged investment objective. The Fund’s exposure to DUOL is impacted by DUOL’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to DUOL at the end of each day. The possibility of the Fund being materially over- or under-exposed to DUOL increases on days when DUOL is volatile near the close of the trading day. Market disruptions, regulatory restrictions and high volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may have difficulty achieving its daily leveraged investment objective for many reasons, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) DUOL. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s desired correlation with DUOL. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to DUOL. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of DUOL. Any of these factors could decrease the correlation between the performance of the Fund and DUOL and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, general market liquidity, exchange trading suspensions and closures, and public health risks. The Fund is subject to the risk that geopolitical events will disrupt markets and adversely affect global economies, markets, and exchanges. Local, regional, or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, conflicts and social unrest or other events could have a significant impact on the Fund, its investments, and the Fund’s ability to achieve its investment objective.

The Fund will be concentrated in the industry to which Duolingo, Inc.is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Duolingo, Inc.is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries. As of the date of this prospectus, DUOL is assigned to the technology sector and the software – application industry.

T-REX 2X LONG DUOL DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

However, they may be less able to adapt to changing market conditions or to respond quickly to competitive challenges or to changes in business, product, financial, or market conditions and may not be able to maintain growth at rates that may be achieved by well-managed smaller and mid-size companies, which may affect the companies’ returns.

T-REX 2X LONG DUOL DAILY TARGET ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Holdings of the Fund may be difficult to buy or sell or may be illiquid, particularly during times of market turmoil. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to buy or sell an illiquid security or derivative instrument at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains, or achieving a high correlation with DUOL. There is no assurance that a security or derivative instrument that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. To the extent that DUOL value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the DUOL. Under such circumstances, the market for DUOL may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments and the Fund’s transactions could exacerbate the price changes of DUOL and may impact the ability of the Fund to achieve its investment objective.

 

In certain cases, the market for DUOL and/or Fund may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have difficulty transacting in it and/or in correlated investments, such as swap contracts. Further, the Fund’s transactions could exacerbate illiquidity and volatility in the price of DUOL and correlated derivative instruments.

Risk [Text Block]

Early Close/Trading Halt Risk. Although an underlying security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times. An exchange or market may close or issue trading halts on specific securities or financial instruments, including the shares of the Fund. Under such circumstances, the ability to buy or sell certain portfolio securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell investments for its portfolio, may disrupt the Fund’s creation/redemption process, and may temporarily prevent investors from buying and selling shares of the Fund. In addition, the Fund may be unable to accurately price its investments, may fail to achieve performance that is correlated with DUOL and may incur substantial losses. If there is a significant intra-day market event and/or DUOL experiences a significant price increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately. Additionally, the Fund may close to purchases and sales of Shares prior to the close of regular trading on Cboe BZX Exchange, Inc. and incur significant losses.

Equity Securities Risk. Publicly issued equity securities, including common stocks, are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests, and/or has exposure to, will cause the net asset value of the Fund to fluctuate. The Fund’s direct investments in common stock of DUOL does not provide leveraged exposure to DUOL and, as a result, if the Fund invests directly in common stock of DUOL to a greater extent, the Fund may not achieve its 200% daily investment objective.

Cash Transaction Risk. The Fund intends to effect creations and redemptions for cash rather than for in-kind securities. As a result, the Fund may not be tax efficient and may incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than if it had effected creations and redemptions in kind. To the extent that such costs are not offset by transaction fees paid by an authorized participant, the Fund may bear such costs, which will decrease the Fund’s net asset value.

T-REX 2X LONG DUOL DAILY TARGET ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund may make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the section entitled “Taxes” in the Statement of Additional Information for more information.

Cash Redemption Risk. The Fund intends to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Prospectus [Line Items]  
Risk [Text Block]
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Risk [Text Block]

Technology Sector Risk. The market prices of technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities may be affected by intense competition, obsolescence of existing technology, general economic conditions and government regulation and may have limited product lines, markets, financial resources, or personnel. Technology companies may experience dramatic and often unpredictable changes in growth rates and competition for qualified personnel. These companies are also heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely impact a company’s profitability. A small number of companies represent a large portion of the technology industry. In addition, a rising interest rate environment tends to negatively affect technology companies, those technology companies seeking to finance expansion would have increased borrowing costs, which may negatively impact earnings. Technology companies having high market valuations may appear less attractive to investors, which may cause sharp decreases in their market prices.

DUOL Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. In addition to the risks associated generally with operating companies, DUOL faces risks unique to its operations including, among others, supply or manufacturing delays, increased material or labor costs or shortages, reduced demand for its products, product liability claims, and the ability to attract, hire and retain key employees or qualified personnel. The trading price of DUOL common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of DUOL’s common stock has been historically and may in the future be traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. DUOL is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political, or regulatory occurrence than a diversified fund.
