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 impact 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 impact 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, 2025 was 107.39%. AFRM’s annualized daily volatility rates were as follows:

2021    141.96%
2022    126.61%
2023    98.91%
2024    78.36%
2025    75.06%

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

AFRM’s annualized performance for the five-year period ended December 31, 2025 was 8.78%. 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 $100.00 on August 29, 2025 and the 52-week low stock price for AFRM is $39.35, which occurred on April 16, 2025. 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.

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, 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.
T-REX 2X LONG AFRM DAILY TARGET ETF | Rebalancing Risk Member

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 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.

Affirm Holdings, Inc. is not affiliated with the Trust, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund and any affiliate are not responsible for the performance of Affirm Holdings, Inc. and make no representation as to the performance of AFRM. Investing in the Fund is not equivalent to investing in AFRM.

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.
T-REX 2X LONG AFRM DAILY TARGET ETF | Technology Sector Risk Member  
Prospectus [Line Items]  
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.
T-REX 2X LONG AFRM DAILY TARGET ETF | Industry Concentration Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Affirm Holdings, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Affirm 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, AFRM is assigned to the software-infrastructure industry.

•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.

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.

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 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.

Prospectus [Line Items]  
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 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.
T-REX 2X LONG AFRM 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 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

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 ALPHABET 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 GOOG’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 GOOG during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how GOOG 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) GOOG volatility; b) GOOG 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 GOOG. The chart below illustrates the impact of two principal factors – GOOG volatility and GOOG performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of GOOG volatility and GOOG performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to GOOG; (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 GOOG.

During periods of higher GOOG volatility, the volatility of GOOG may affect the Fund’s return as much as, or more than, the return of GOOG. 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 GOOG 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 GOOG provided no return over a one-year period during which GOOG 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 GOOG’s return is flat. For instance, if GOOG’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 GOOG 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 GOOG. 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.

T-REX 2X LONG ALPHABET 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 GOOG 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 GOOG, 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 GOOG 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 GOOG does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with GOOG 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 index, reduce its leverage or close.
T-REX 2X LONG ALPHABET 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.

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 exchanged-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.

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, 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 ALPHABET 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 GOOG, 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 GOOG 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 ALPHABET 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 GOOG at the market close on the first trading day and the value of GOOG at the time of purchase. If GOOG gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if GOOG 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 GOOG.

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 prior to the close of trading on the Exchange and incur significant losses.
T-REX 2X LONG ALPHABET 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 GOOG and therefore achieve its daily leveraged investment objective. The Fund’s exposure to GOOG is impacted by GOOG’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to GOOG at the end of each day. The possibility of the Fund being materially over- or under-exposed to GOOG increases on days when GOOG 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) GOOG. 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 GOOG. 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 GOOG. 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 GOOG. Any of these factors could decrease the correlation between the performance of the Fund and GOOG 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 ALPHABET 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] -Capitalization Company Risk. Investments in mega-capitalization companies may involve certain risks. Although mega-cap companies are typically well-established and may have substantial financial resources, broad product lines, and diversified operations, they may be less able to respond quickly to changes in market conditions, technological developments, or shifts in consumer preferences. As a result, such companies may experience slower growth rates compared to smaller or mid-sized companies.
In addition, mega-cap companies may be subject to increased regulatory scrutiny, as well as heightened exposure to global economic, political, and geopolitical risks due to their multinational operations. Their size and market prominence may make it more difficult to achieve significant growth, particularly during periods of economic expansion. While securities of mega-cap companies may be less volatile than those of smaller companies, they may underperform other segments of the market, which could adversely affect the Fund’s investment returns.
T-REX 2X LONG ALPHABET 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 GOOG. 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 GOOG value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in GOOG. Under such circumstances, the market for securities of GOOG may lack sufficient liquidity for all market participants' trades. Therefore, the Fund may have more difficulty transacting in GOOG or financial instruments and the Fund's transactions could exacerbate the price changes of GOOG and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for certain securities in GOOG 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 GOOG 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 GOOG and may incur substantial losses. If there is a significant intra-day market event and/or GOOG 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 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 GOOG does not provide leveraged exposure to GOOG and, as a result, if the Fund invests directly in common stock of GOOG 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 ALPHABET 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

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 APH 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 APH’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 impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of APH during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how APH 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) APH volatility; b) APH 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 APH. 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 APH volatility and APH performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to APH; (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 APH.

During periods of higher APH volatility, the volatility of APH may affect the Fund’s return as much as, or more than, the return of APH. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of APH 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 APH provided no return over a one-year period during which APH 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 APH’s return is flat. For instance, if APH’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 APH 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 APH. 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.

APH’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 27.21%. APH’s annualized daily volatility rates were as follows:
    
2021    20.78%
2022    29.71%
2023    18.46%
2024    26.46%
2025    36.70%

APH’s annualized performance for the five-year period ended December 31, 2025 was 32.80%. Historical volatility and performance are not indications of what APH volatility and performance will be in the future. APH’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 APH is $167.04 on January 27, 2026 and the 52-week low stock price for APH is $62.55, which occurred on April 21, 2025. APH’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG APH 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 APH 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 APH, 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 APH 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 APH does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with APH 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 APH 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.

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, 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.

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 APH, 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 APH 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 APH 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 APH at the market close on the first trading day and the value of APH at the time of purchase. If APH gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if APH 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 APH.

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 APH 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 APH and therefore achieve its daily leveraged investment objective. The Fund’s exposure to APH is impacted by APH’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to APH at the end of each day. The possibility of the Fund being materially over- or under-exposed to APH increases on days when APH 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) APH. 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 APH. 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 APH. 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 APH. Any of these factors could decrease the correlation between the performance of the Fund and APH 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.

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.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Amphenol Corporation is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Amphenol 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, APH is assigned to the electronics components industry.

•Electronics Components Industry Risk.    Electronics components companies can be significantly affected by competitive pressures, fluctuations in demand, technological developments, rapid product obsolescence, cyclical market patterns, evolving industry standards, and reliance on global supply chains. The market for products produced by electronics components companies is characterized by intense competition, frequent innovation, short product life cycles, and sensitivity to broader economic conditions. The success of electronics components companies depends in substantial part on their ability to anticipate technological changes, manage supply chain disruptions, introduce new products on a timely basis, and meet customer specifications and quality requirements. Unexpected shifts in demand, shortages of key raw materials or subcomponents, or changes in the technologies used in end markets could have a material adverse effect on a participant’s operating results. Many electronic component companies rely on a combination of patents, trade secrets, and specialized manufacturing know-how to protect their products and processes. There can be no assurance that the steps taken by electronics components companies to protect their proprietary rights will be adequate to prevent misappropriation or that competitors will not independently develop technologies or products that are substantially equivalent or superior.
T-REX 2X LONG APH 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 APH 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 APH. 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 APH value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the APH. Under such circumstances, the market for APH 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 APH and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for APH 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 APH 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 APH and may incur substantial losses. If there is a significant intra-day market event and/or APH 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.

Prospectus [Line Items]  
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 APH does not provide leveraged exposure to APH and, as a result, if the Fund invests directly in common stock of APH to a greater extent, the Fund may not achieve its 200% daily investment objective.
T-REX 2X LONG APH 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 APH 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

The value of an individual security or particular type of security may perform differently from the market as a whole. In addition to the risks associated generally with investments in equity securities, APH faces risks unique to its operations, including dependence on demand from industrial, automotive, communications, and defense end markets, exposure to cyclical capital spending, supply chain disruptions, raw material cost fluctuations, and competitive pricing pressures. APH’s results may also be affected by its global manufacturing footprint and reliance on acquisitions to support growth. The trading price of APH common stock may be volatile, and APH’s business strategy and end-market exposure may evolve.

Risk [Text Block] Electronics Components Industry Risk.    Electronics components companies can be significantly affected by competitive pressures, fluctuations in demand, technological developments, rapid product obsolescence, cyclical market patterns, evolving industry standards, and reliance on global supply chains. The market for products produced by electronics components companies is characterized by intense competition, frequent innovation, short product life cycles, and sensitivity to broader economic conditions. The success of electronics components companies depends in substantial part on their ability to anticipate technological changes, manage supply chain disruptions, introduce new products on a timely basis, and meet customer specifications and quality requirements. Unexpected shifts in demand, shortages of key raw materials or subcomponents, or changes in the technologies used in end markets could have a material adverse effect on a participant’s operating results. Many electronic component companies rely on a combination of patents, trade secrets, and specialized manufacturing know-how to protect their products and processes.

ETF Investing Risk. The Fund may invest in other ETFs for cash management. As a result, the Fund will be subject to the risks associated with the underlying ETFs in which they invest and the securities held by those ETFs. These risks include investment risk related to the underlying portfolio holdings, as well as structural risks of ETFs, such as market price fluctuations, trading at prices above or below net asset value, limited secondary market liquidity, and potential trading halts. Investments in ETFs also involve the layering of expenses, as shareholders of the Fund will indirectly bear a portion of the operating expenses of the underlying ETFs in addition to the Fund's own expenses. To the extent the Fund invests in ETFs within the same group of investment companies, potential conflicts of interest may arise. The performance of the Fund may be adversely affected by the performance of the underlying ETFs and their portfolio investments.

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 APPLE 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 AAPL’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 AAPL during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how AAPL 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) AAPL volatility; b) AAPL 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 AAPL. 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 AAPL volatility and AAPL performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to AAPL; (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 AAPL.

During periods of higher AAPL volatility, the volatility of AAPL may affect the Fund’s return as much as, or more than, the return of AAPL. 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 AAPL 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 AAPL provided no return over a one-year period during which AAPL 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 AAPL’s return is flat. For instance, if AAPL’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 AAPL 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 AAPL. 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.

T-REX 2X LONG APPLE 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 AAPL 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 AAPL, 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 AAPL 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 AAPL does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AAPL 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.
T-REX 2X LONG APPLE 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.

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.

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, 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.

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 AAPL, 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 AAPL 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 APPLE 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 AAPL at the market close on the first trading day and the value of AAPL at the time of purchase. If AAPL gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if AAPL 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 AAPL.

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.

Prospectus [Line Items]  
Risk [Text Block]
Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to AAPL and therefore achieve its daily leveraged investment objective. The Fund’s exposure to AAPL is impacted by AAPL’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to AAPL at the end of each day. The possibility of the Fund being materially over- or under-exposed to AAPL increases on days when AAPL 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) AAPL. 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 AAPL. 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 AAPL. 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 AAPL. Any of these factors could decrease the correlation between the performance of the Fund and AAPL 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 Trust, the Fund and any affiliate are not responsible for the performance of Apple, Inc. and make no representation as to the performance of AAPL. Investing in the Fund is not equivalent to

T-REX 2X LONG APPLE DAILY TARGET ETF | Technology Sector Risk Member  
Prospectus [Line Items]  
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.
T-REX 2X LONG APPLE DAILY TARGET ETF | Industry Concentration Risk Member

Risk [Text Block]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Apple, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Apple, 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, AAPL is assigned to the computer manufacturing industry.

•Computer Manufacturing Industry Risk. Computer manufacturing companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Computer manufacturing companies may have limited product lines, markets, financial resources, or personnel. The products of computer manufacturing companies may face rapid product obsolescence due to technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Failure to introduce new products, develop and maintain a loyal customer base, or achieve general market acceptance for their products could have a material adverse effect on a company’s business. Companies in the computer manufacturing sector are heavily dependent on intellectual property and the loss of patent, copyright and trademark protections may adversely affect the profitability of these companies.
T-REX 2X LONG APPLE 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.

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 AAPL. 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 AAPL value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the AAPL. Under such circumstances, the market for AAPL 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 AAPL and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for AAPL 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 AAPL 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 AAPL and may incur substantial losses. If there is a significant intra-day market event and/or AAPL 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 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 AAPL does not provide leveraged exposure to AAPL and, as a result, if the Fund invests directly in common stock of AAPL to a greater extent, the Fund may not achieve its 200% daily investment objective.

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 APPLE 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Mega-Capitalization Company Risk. Investments in mega-capitalization companies may involve certain risks. Although mega-cap companies are typically well-established and may have substantial financial resources, broad product lines, and diversified operations, they may be less able to respond quickly to changes in market conditions, technological developments, or shifts in consumer preferences. As a result, such companies may experience slower growth rates compared to smaller or mid-sized companies.

In addition, mega-cap companies may be subject to increased regulatory scrutiny, as well as heightened exposure to global economic, political, and geopolitical risks due to their multinational operations. Their size and market prominence may make it more difficult to achieve significant growth, particularly during periods of economic expansion. While securities of mega-cap companies may be less volatile than those of smaller companies, they may underperform other segments of the market, which could adversely affect the Fund’s investment returns.

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 BMNR 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 BMNR’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 impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BMNR during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how BMNR 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) BMNR volatility; b) BMNR 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 BMNR. 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 BMNR volatility and BMNR performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to BMNR; (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 BMNR.

During periods of higher BMNR volatility, the volatility of BMNR may affect the Fund’s return as much as, or more than, the return of BMNR. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of BMNR 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 BMNR provided no return over a one-year period during which BMNR 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 BMNR’s return is flat. For instance, if BMNR’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 BMNR 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 BMNR. 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.

BMNR’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 474.27%. BMNR’s annualized daily volatility rates were as follows:

2021    370.15%
2022    297.94%
2023    365.74%
2024    252.04%
2025    771.84%

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

BMNR’s annualized performance for the five-year period ended December 31, 2025 was -12.45%. Historical volatility and performance are not indications of what BMNR volatility and performance will be in the future. The trading price of BMNR’s common stock is likely to be volatile compared to the market. The trading prices of technology company securities historically have been highly volatile. The trading price of BMNR’s common stock has been and is likely to continue to be subject to wide fluctuations.  By way of example, currently BMNR’s 52-week high stock price was $161.00 on July 3, 2025, and its 52-week low stock price was $3.20 on May 19, 2025. BMNR’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG BMNR 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 BMNR 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 BMNR, 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 BMNR 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 BMNR does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with BMNR 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 BMNR 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.

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, 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 BMNR 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 BMNR, 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 BMNR 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 BMNR 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 BMNR at the market close on the first trading day and the value of BMNR at the time of purchase. If BMNR gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if BMNR 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 BMNR.

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 BMNR 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 BMNR and therefore achieve its daily leveraged investment objective. The Fund’s exposure to BMNR is impacted by BMNR’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to BMNR at the end of each day. The possibility of the Fund being materially over- or under-exposed to BMNR increases on days when BMNR 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) BMNR. 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 BMNR. 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 BMNR. 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 BMNR. Any of these factors could decrease the correlation between the performance of the Fund and BMNR and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Risk [Text Block]
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 BMNR DAILY TARGET ETF | Industry Concentration Risk Member

Risk [Text Block]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Bitmine Immersion Technologies, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Bitmine Immersion Technologies, 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, BMNR is assigned to the capital markets industry.

•Capital Markets Industry Risk.  The Fund may invest in companies operating within the capital markets industry, including investment banks, asset managers, securities exchanges, and other financial services providers. These
companies are subject to extensive government regulation and oversight, which can change rapidly and unpredictably, potentially affecting profitability and business operations. The performance of capital markets firms is closely tied to the health of global financial markets, investor sentiment, and the level of trading, underwriting, and asset management activity. These companies may be adversely affected during periods of market volatility, declining equity or debt issuance, or reduced investor participation. In addition, capital markets firms often have significant exposure to counterparty, credit, and liquidity risk, particularly in times of financial stress. Operational failures, cybersecurity breaches, and reputational damage can also materially impact their value. As a result, adverse developments in the capital markets industry may negatively affect the Fund’s investments and performance.
T-REX 2X LONG BMNR 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 BMNR 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 BMNR. 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 BMNR value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the BMNR. Under such circumstances, the market for BMNR 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 BMNR and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for BMNR 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 BMNR 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 BMNR and may incur substantial losses. If there is a significant intra-day market event and/or BMNR 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.

Prospectus [Line Items]  
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 BMNR does not provide leveraged exposure to BMNR and, as a result, if the Fund invests directly in common stock of BMNR to a greater extent, the Fund may not achieve its 200% daily investment objective.
T-REX 2X LONG BMNR 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 BMNR 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

BMNR 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, BMNR is subject to risks unique to its operations and business strategy, including volatility in the value of Ethereum and other digital assets, failures or disruptions affecting blockchain networks, the loss, theft or compromise of cryptographic keys, cybersecurity breaches, evolving laws, regulations and governmental actions affecting digital assets or blockchain-related activities, and the ability to attract, hire and retain key employees and other qualified personnel.

BMNR holds digital assets as part of its corporate treasury strategy. The market value of Ethereum and other digital assets is highly volatile and may experience significant and rapid price fluctuations. A decline in the value of BMNR's digital asset holdings could materially adversely affect its financial condition, results of operations, liquidity, prospects or stock price. BMNR's digital asset holdings also expose it to custody risks, cybersecurity risks, accounting and valuation risks, potential impairment charges, technological risks and evolving regulatory requirements. The loss, theft, destruction or compromise of digital assets or the private cryptographic keys associated with those assets may be irreversible and could result in a substantial or complete loss of the affected assets.
There is no comprehensive or settled regulatory framework governing Ethereum, Bitcoin and other digital assets or the markets in which they trade. U.S. federal and state legislators, regulators and law enforcement agencies continue to examine digital asset networks, market participants and related activities and may adopt new laws, regulations, interpretations or enforcement policies that adversely affect digital assets or companies with significant digital asset exposure. Regulatory developments could restrict the use, ownership, custody, trading or transfer of digital assets, increase BMNR's compliance costs, reduce the value or liquidity of its digital asset holdings or otherwise materially adversely affect its business and operations.

The trading price of BMNR common stock historically has been and is likely to continue to be volatile. In addition, a large proportion of BMNR's common stock has historically been, and may in the future be, traded by short sellers, which may affect the supply of and demand for its common stock and further increase volatility in its market price. BMNR is a highly dynamic company, and its operations, business strategy and services may change over time. Any of these risks could materially and adversely affect BMNR's business, financial condition, results of operations, prospects or stock price.

Because the Fund seeks daily investment results, before fees and expenses, that correspond to twice (2X) the daily performance of BMNR common stock, increased volatility in BMNR common stock may result in increased volatility of the Fund and may increase the risk of significant losses. The Fund does not invest directly in Ethereum, Bitcoin or other digital assets.

Blockchain Risk. Blockchain technology is an emerging and rapidly evolving technology that is subject to a variety of risks. Blockchain networks may experience technical defects, coding errors, software bugs, cyberattacks, security breaches, forks, network congestion, delays, outages, or other disruptions that could impair their functionality or reliability. The adoption and development of blockchain technology is subject to significant uncertainty and may be affected by changes in technology, competition from alternative technologies, market acceptance, and evolving legal and regulatory requirements. In addition, blockchain networks depend on participants to maintain and validate transactions, and there can be no assurance that such networks will continue to operate as intended. Any interruption, failure, security vulnerability or reduction in the use or acceptance of blockchain technology could adversely affect companies that develop, utilize or maintain blockchain-based systems or that hold or transact in digital assets. To the extent BMNR's business, operations or corporate treasury strategy depends on blockchain technology or digital assets that utilize blockchain technology, such events could materially adversely affect BMNR and, consequently, the Fund.

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.

The performance of capital markets firms is closely tied to the health of global financial markets, investor sentiment, and the level of trading, underwriting, and asset management activity. These companies may be adversely affected during periods of market volatility, declining equity or debt issuance, or reduced investor participation. In addition, capital markets firms often have significant exposure to counterparty, credit, and liquidity risk, particularly in times of financial stress.

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.

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 CRCL’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 CRCL during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how CRCL 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) CRCL volatility; b) CRCL 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 CRCL. 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 CRCL volatility and CRCL performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to CRCL; (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 CRCL.

During periods of higher CRCL volatility, the volatility of CRCL may affect the Fund’s return as much as, or more than, the return of CRCL. 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 CRCL 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 CRCL provided no return over a one-year period during which CRCL 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 CRCL’s return is flat. For instance, if CRCL’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 CRCL 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 CRCL. 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.

CRCL’s annualized historical daily volatility rate for the one-year period ended December 31, 2025 was 252.81%. CRCL’s annualized daily volatility rates were as follows:
 
2025       252.81%
 
Volatility for a shorter period of time may have been substantially higher.
 
CRCL’s annualized performance for the one-year period ended December 31, 2025 was 411.67%. Historical volatility and performance are not indications of what CRCL volatility and performance will be in the future. CRCL’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 CRCL is $298.99 on June 23, 2025 and the 52-week low stock price for CRCL is $49.90, which occurred on February 5, 2026. CRCL’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG CRCL 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 CRCL 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 CRCL, 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 CRCL 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 CRCL does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with CRCL 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 CRCL 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.

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, 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 CRCL 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 CRCL, 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 CRCL 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 CRCL 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 CRCL at the market close on the first trading day and the value of CRCL at the time of purchase. If CRCL gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CRCL 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 CRCL.

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 CRCL 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 CRCL and therefore achieve its daily leveraged investment objective. The Fund’s exposure to CRCL is impacted by CRCL’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to CRCL at the end of each day. The possibility of the Fund being materially over- or under-exposed to CRCL increases on days when CRCL 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) CRCL. 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 CRCL. 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 CRCL. 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 CRCL. Any of these factors could decrease the correlation between the performance of the Fund and CRCL 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 CRCL DAILY TARGET ETF | Industry Concentration Risk Member

Risk [Text Block]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Circle Internet Group, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Circle Internet Group, 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, CRCL is assigned to the capital markets industry.

•Capital Markets Risk. The capital markets industry includes companies that facilitate the issuance, buying, and selling of financial securities and other investments, such as broker-dealers, investment banks, asset managers, securities exchanges, and financial data providers. These companies may be adversely affected by market volatility, reduced trading activity, changes in interest rates, or a decline in the value of assets under management. Their profitability can be sensitive to economic and market conditions, regulatory changes, competition, and technological disruption. In addition, capital markets companies are subject to operational risks, including settlement failures, cybersecurity incidents, and compliance costs. Adverse developments in the capital markets sector could negatively impact the value of the Fund’s investments in such companies.
T-REX 2X LONG CRCL 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 CRCL 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 CRCL. 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 CRCL value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the CRCL. Under such circumstances, the market for CRCL may lack sufficient liquidity for all market participants trades. Therefore, the Fund may have more difficulty transacting in the securities or financial instruments instruments and the Fund's transactions could exacerbate the price changes of CRCL and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for CRCL 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 CRCL 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 CRCL and may incur substantial losses. If there is a significant intra-day market event and/or CRCL 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.
T-REX 2X LONG CRCL DAILY TARGET ETF | Equity Securities Risk Member  
Prospectus [Line Items]  
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 CRCL does not provide leveraged exposure to CRCL and, as a result, if the Fund invests directly in common stock of CRCL to a greater extent, the Fund may not achieve its 200% daily investment objective.
T-REX 2X LONG CRCL DAILY TARGET ETF | Cash Transaction Risk Member

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 CRCL 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

CRCL 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, CRCL faces risks unique due to its business model. CRCL, which operates under the brand name CRCL, is a global financial technology company that specializes in digital currencies and blockchain technology. CRCL is best known for issuing the stablecoin USDC, a digital currency pegged to the U.S. dollar. CRLC also provides various financial and technology services to businesses and developers, enabling them to integrate stablecoins and blockchain technology into their operations. CRCL operations subjects it to the following risks:

•Interest Rate Risk: CRCL’s revenue model heavily relies on the interest earned from reserves that back its USDC stablecoin, which are primarily held in short-term U.S. Treasury bills. A decline in interest rates could significantly reduce Circle's income and impact its profitability.
•Regulatory Uncertainty: The cryptocurrency regulatory landscape is volatile and evolving, with varying standards across different jurisdictions. Stricter regulations, increased oversight, or changes in how regulatory bodies interpret and apply existing laws could hinder CRCL’s growth or pose threats to its business model. While certain legislative and regulatory initiatives aim to bring more regulatory clarity, stricter capital requirements or limits on interest income could negatively impact CRCL’s margins.
•Competitive Pressure: The stablecoin market is becoming increasingly competitive, with rivals and potential entrants from traditional banks exploring stablecoin offerings. This could erode CRCL’s market share and impact its revenue and profitability.
•Macroeconomic Volatility: Broad economic factors, such as shifts in interest rates or volatility in the cryptocurrency market, can affect CRCL’s financial performance. A pivot to lower interest rates could reduce interest income from reserves, while a crypto bear market could shrink USDC's circulation and impact revenue.
•Dependence on Partnerships: While CRCL has expanded its product offerings and revenue streams, it still relies on significant partnerships for the distribution and adoption of USDC. If these partnerships change or end, it could impact CRCL’s distribution costs and reserve income.
•De-pegging Risk: While USDC is designed to be redeemable 1:1 for U.S. dollars, there is a risk of a "de-peg," where the token could trade below $1 on third-party platforms. This could be triggered by events like a run on a bank holding CRCL’s assets.
•Cybersecurity Risks: CRCL’s reliance on third-party systems and the increasing sophistication of cyberattacks expose the company to potential security breaches that could affect its operations, data, and reputation. 
The trading price of CRCL common stock is likely to be volatile. Additionally, CRCL’s common stock 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. CRCL 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 CRWV 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 CRWV’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 impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRWV during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how CRWV 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) CRWV volatility; b) CRWV 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 CRWV. 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 CRWV volatility and CRWV performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to CRWV; (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 CRWV.

During periods of higher CRWV volatility, the volatility of CRWV may affect the Fund’s return as much as, or more than, the return of CRWV. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRWV 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 CRWV provided no return over a one-year period during which CRWV 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 CRWV’s return is flat. For instance, if CRWV’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 CRWV 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 CRWV. 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.

CRWV’s annualized historical daily volatility rate for the one-year period ended December 31, 2025 was 124.16%. CRWV’s annualized daily volatility rates were as follows:
 
2025      124.16%
 
Volatility for a shorter period of time may have been substantially higher.
 
CRWV’s annualized performance for the one-year period ended December 31, 2025 was 114.23%. The market prices of CRWV’s common stock are subject to fluctuations due both to factors affecting market prices for publicly traded equity securities generally and to factors affecting CRWV’s common stock. CRWV’s stock price may be more volatile than the market. Market prices of CRWV’s common stock have been volatile at times in the past, and may be volatile in the future. By way of example, currently, CRWV's 52-week high stock price was $187.00 on June 20, 205, and its 52-week low stock price was $33.52 on April 21, 2025. CRWV’s high and low stock price may change significantly over a short period of time.

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 CRWV 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 CRWV, 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 CRWV 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 CRWV does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with CRWV 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 CRWV 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.

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, 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.

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 CRWV, 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 CRWV 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 CRWV 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 CRWV at the market close on the first trading day and the value of CRWV at the time of purchase. If CRWV gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CRWV 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 CRWV.

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.

Prospectus [Line Items]  
Risk [Text Block]
Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to CRWV and therefore achieve its daily leveraged investment objective. The Fund’s exposure to CRWV is impacted by CRWV’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to CRWV at the end of each day. The possibility of the Fund being materially over- or under-exposed to CRWV increases on days when CRWV 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) CRWV. 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 CRWV. 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 CRWV. 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 CRWV. Any of these factors could decrease the correlation between the performance of the Fund and CRWV and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

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.

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 CRWV. 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 CRWV value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the CRWV. Under such circumstances, the market for CRWV 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 CRWV and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for CRWV 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 CRWV 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 CRWV and may incur substantial losses. If there is a significant intra-day market event and/or CRWV 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 CRWV does not provide leveraged exposure to CRWV and, as a result, if the Fund invests directly in common stock of CRWV 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.

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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.

•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.

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, CRWV 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 CRWV common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of CRWV’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. CRWV is a highly dynamic company, and its operations, including its products and services, may change.

Information Technology Sector 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.

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 DJT 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 DJT’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 DJT during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how DJT 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) DJT volatility; b) DJT 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 DJT. 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 DJT volatility and DJT performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to DJT; (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 DJT.

During periods of higher DJT volatility, the volatility of DJT may affect the Fund’s return as much as, or more than, the return of DJT. 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 DJT 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 DJT provided no return over a one-year period during which DJT 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 DJT’s return is flat. For instance, if DJT’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 DJT 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 DJT. 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.

DJT’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 213.79%. DJT’s annualized daily volatility rates were as follows:

2021    747.35%
2022    119.48%
2023    70.47%
2024    161.62%
2025    77.45%

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

DJT’s annualized performance for the five-year period ended December 31, 2025 was 6.94%. Historical volatility and performance are not indications of what DJT volatility and performance will be in the future. The trading price of DJT’s common stock is likely to be volatile, and may be more volatile than the markets. By way of example, currently, DJT’s 52-week high stock price was $27.78 on May 14, 2025, and its 52-week low stock price was $8.31 on March 20, 2026. DJT’s high and low stock price may change significantly over a short period of time.

The following factors may cause volatility of the price of DJT’s common stock: results of operations that vary from the expectations of securities analysts and investors; results of operations that vary from DJT’s competitors; changes in expectations as to DJT’s future financial performance, including financial estimates and investment recommendations by securities analysts and investors; declines in the market prices of stocks generally; strategic actions by DJT or its competitors; announcements by DJT or its competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments; announcements of estimates by third parties of actual or anticipated changes in the size of DJT’s user base or the level of user engagement; any significant change in DJT’s management; changes in general economic or market conditions or trends in DJT’s industry or markets; changes in business or regulatory conditions, including new laws or regulations or new interpretations of existing laws or regulations applicable to DJT’s business; investor perceptions of the investment opportunity associated with DJT’s common stock relative to other investment alternatives; the public’s response to press releases or other public announcements by DJT or third parties; litigation involving DJT or DJT’s industry, or both, or investigations by regulators into DJT’s operations or those of DJT’s competitors; guidance, if any, that DJT’s provides to the public, any changes in this guidance or DJT’s failure to meet this guidance; the development and sustainability of an active trading market for DJT’s common stock; actions by institutional or activist stockholders; and developments in new legislation and pending lawsuits or regulatory actions, including interim or final rulings by judicial or regulatory bodies.

T-REX 2X LONG DJT 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 DJT 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 DJT, 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 DJT 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 DJT does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with DJT 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 DJT 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.

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, 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.

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 DJT, 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 DJT 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 DJT 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 DJT at the market close on the first trading day and the value of DJT at the time of purchase. If DJT gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if DJT 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 DJT.

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 DJT 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 DJT and therefore achieve its daily leveraged investment objective. The Fund’s exposure to DJT is impacted by DJT’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to DJT at the end of each day. The possibility of the Fund being materially over- or under-exposed to DJT increases on days when DJT 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) DJT. 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 DJT. 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 DJT. 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 DJT. Any of these factors could decrease the correlation between the performance of the Fund and DJT and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Trump Media & Technology Group Corp. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Trump Media & Technology Group Corp. 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, DJT is assigned to the interactive media and services industry.
T-REX 2X LONG DJT 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.

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 DJT. 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 DJT value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in
the DJT. Under such circumstances, the market for DJT 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 DJT and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for DJT 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 DJT 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 DJT and may incur substantial losses. If there is a significant intra-day market event and/or DJT 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 DJT does not provide leveraged exposure to DJT and, as a result, if the Fund invests directly in common stock of DJT 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 DJT 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid than those of large-capitalization companies, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

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 EOSE 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 EOSE’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 impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of EOSE during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how EOSE 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) EOSE volatility; b) EOSE 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 EOSE. 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 EOSE volatility and EOSE performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to EOSE; (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 EOSE.
During periods of higher EOSE volatility, the volatility of EOSE may affect the Fund’s return as much as, or more than, the return of EOSE. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of EOSE 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 EOSE provided no return over a one-year period during which EOSE 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 EOSE’s return is flat. For instance, if EOSE’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 EOSE 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 EOSE. 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.

EOSE’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 114.63%. EOSE’s annualized daily volatility rates were as follows:

2021    83.06%
2022    137.77%
2023    128.35%
2024    106.50%
2025    109.59%

EOSE’s annualized performance for the five-year period ended December 31, 2025 was -11.27%. Historical volatility and performance are not indications of what EOSE volatility and performance will be in the future. EOSE’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 EOSE is $19.86 on November 10, 2025 and the 52-week low stock price for EOSE is $3.69, which occurred on June 4, 2025. EOSE’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X LONG EOSE 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 EOSE 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 EOSE, 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 EOSE 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 EOSE does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with EOSE 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 EOSE 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.

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, 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.

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 EOSE, 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 EOSE 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 EOSE 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 EOSE at the market close on the first trading day and the value of EOSE at the time of purchase. If EOSE gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if EOSE 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 EOSE.

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 EOSE 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 EOSE and therefore achieve its daily leveraged investment objective. The Fund’s exposure to EOSE is impacted by EOSE’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to EOSE at the end of each day. The possibility of the Fund being materially over- or under-exposed to EOSE increases on days when EOSE 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) EOSE. 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 EOSE. 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 EOSE. 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 EOSE. Any of these factors could decrease the correlation between the performance of the Fund and EOSE 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]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Eos Energy Enterprises, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Eos Energy Enterprises, 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, EOSE is assigned to the electrical equipment and parts industry.

•Electrical Equipment and Parts Industry Risk.    The electrical equipment and parts industry is exposed to risks arising from cyclical demand, reliance on global supply chains, and sensitivity to raw material and energy costs. Businesses in this sector face competitive pressures, rapid technological change, and the need for continuous innovation to meet evolving efficiency, safety, and sustainability standards. Regulatory requirements related to product safety, environmental compliance, and energy usage may increase costs or restrict certain markets. Supply chain disruptions, shortages of key components, and reliance on specialized labor can also affect production and delivery capabilities. In addition, fluctuations in construction activity, industrial investment, and overall economic conditions directly influence demand. These factors collectively may materially impact the performance and profitability of companies in the industry.
T-REX 2X LONG EOSE 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 EOSE. 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 EOSE value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the EOSE. Under such circumstances, the market for EOSE 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 EOSE and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for EOSE 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 EOSE 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 EOSE and may incur substantial losses. If there is a significant intra-day market event and/or EOSE 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 EOSE does not provide leveraged exposure to EOSE and, as a result, if the Fund invests directly in common stock of EOSE 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 EOSE 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.
•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.

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.

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 impact 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 impact 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, 2025 was 99.19%. GLXY’s annualized daily volatility rates were as follows:
    
2021    121.34%
2022    114.88%
2023    79.78%
2024    85.30%
2025    87.04%

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

GLXY’s annualized performance for the five-year period ended December 31, 2025 was 21.09%. 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 $45.92 on October 21, 2025 and the 52-week low stock price for GLXY is $10.75, which occurred on April 21, 2025. GLXY’s 52-week high and low stock price may change significantly over a short period of time.

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.

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.

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, 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 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.
T-REX 2X LONG GLXY 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 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.

Industry Concentration Risk. 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 capital markets industry.

•Capital Markets Risk. The capital markets industry includes companies that facilitate the issuance, buying, and selling of financial securities and other investments, such as broker-dealers, investment banks, asset managers, securities exchanges, and financial data providers. These companies may be adversely affected by market volatility, reduced trading activity, changes in interest rates, or a decline in the value of assets under management. Their profitability can be sensitive to economic and market conditions, regulatory changes, competition, and technological disruption. In addition, capital markets companies are subject to operational risks, including settlement failures, cybersecurity incidents, and compliance costs. Adverse developments in the capital markets sector could negatively impact the value of the Fund’s investments in such companies.
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.

While mid-cap companies often have greater growth potential than large-cap firms, they may also be more sensitive to changing market conditions, competitive pressures, and economic downturns. Their securities may experience greater price volatility and may be less liquid than those of large-cap companies, which could affect their market value and investment 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.

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 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.
T-REX 2X LONG GLXY 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 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.

•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.

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.

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.

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 GME 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 GME’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 GME during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how GME 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) GME volatility; b) GME 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 GME. 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 GME volatility and GME performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to GME; (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 GME.

During periods of higher GME volatility, the volatility of GME may affect the Fund’s return as much as, or more than, the return of GME. 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 GME 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 GME provided no return over a one-year period during which GME 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 GME’s return is flat. For instance, if GME’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 GME 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 GME. 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.

GME’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 151.49%. GME’s annualized daily volatility rates were as follows:
    
2021    269.48%
2022    99.54%
2023    78.10%
2024    149.14 %
2025    55.81%

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

GME’s annualized performance for the five-year period ended December 31, 2025 was 33.62%. Historical volatility and performance are not indications of what GME volatility and performance will be in the future. The price of GME’s common stock has been extremely volatile relative to the market and may continue to be volatile due to numerous circumstances. The market price of GME’s common stock has fluctuated, and may continue to fluctuate, widely, due to many factors, some of which may be beyond GME’s control. These factors include, without limitation: large stockholders exiting their position in common stock or an increase or decrease in the short interest in common stock; actual or anticipated fluctuations in GME’s financial and operating results; the timing and allocations of new product releases including new console launches; the costs associated with the exit of unprofitable markets, businesses or stores; negative public perception of GME, GME’s competitors or industry; and overall general market fluctuations.

Stock markets in general and GME’s stock price in particular have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies and GME. These broad market fluctuations may adversely affect the trading price of GME’s common stock. By way of example, currently, the 52-week high stock price for GME is $35.81 on May 28, 2025 and the 52-week low stock price for GME is $19.93, which occurred on November 20, 2025. GME’s 52-week high and low stock price may change significantly over a short period of time. In particular, a large proportion of GME’s common stock has been and may continue to be traded by short sellers which has put and may continue to put pressure on the supply and demand for GME’s common stock, further influencing volatility in its market price. These and other external factors have caused and may continue to cause the market price and demand for GME’s common stock to fluctuate substantially.

T-REX 2X LONG GME 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 GME 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 GME, 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 GME 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 GME does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with GME 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 GME 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.

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, 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 GME 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 GME, 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 GME 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 GME 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 GME 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 GME at the market close on the first trading day and the value of GME at the time of purchase. If GME gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if GME 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 GME.

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 GME 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 GME and therefore achieve its daily leveraged investment objective. The Fund’s exposure to GME is impacted by GME’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to GME at the end of each day. The possibility of the Fund being materially over- or under-exposed to GME increases on days when GME 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) GME. 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 GME. 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 GME. 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 GME. Any of these factors could decrease the correlation between the performance of the Fund and GME and may hinder the Fund’s ability to meet its daily leveraged investment objective on or around that day.
T-REX 2X LONG GME DAILY TARGET ETF | Market Risk Member

Risk [Text Block]
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.

Indirect Investment Risk. GameStop Corp. is not affiliated with the Trust, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund and any affiliate are not responsible for the performance of GameStop Corp. and make no representation as to the performance of GME. Investing in the Fund is not equivalent to investing in GME.

Risk [Text Block] Underlying Security Investing Risk. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally.

T-REX 2X LONG GME DAILY TARGET ETF | Industry Concentration Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Industry Concentration Risk. The Fund will be concentrated in the industry to which GameStop Corp. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which GameStop Corp. 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, GME is assigned to the specialty retail industry.

•Video Gaming and eSports Companies Risk. The Fund will be sensitive to, and its performance may depend to a greater extent on, the overall condition of video gaming and eSports companies. Video gaming and eSports companies face intense competition, both domestically and internationally, may have limited product lines, markets, financial resources, or personnel, may have products that face rapid obsolescence, and are heavily dependent on the protection of patent and intellectual property rights. Video gaming companies may be dependent on one or a small number of product or product franchises for a significant portion of their revenue and profits. They may also be subject to shifting consumer preferences, including preferences with respect to gaming console platforms, and changes in consumer discretionary spending. Such factors may adversely affect the profitability and value of video gaming and eSports companies. Video gaming companies are also subject to increasing regulatory constraints, particularly with respect to cybersecurity and privacy, and may be subject to sophisticated intellectual property infringement schemes and piracy efforts. Video gaming and eSports companies may have significant exposure to the following industries, and therefore may be subject to the risks associated with such industries.
T-REX 2X LONG GME 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 GME DAILY TARGET ETF | Money Market Instrument Risk Member

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 GME 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 GME. 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 GME value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the GME. Under such circumstances, the market for GME 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 GME and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for GME 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 GME and correlated derivative instruments.
T-REX 2X LONG GME DAILY TARGET ETF | Early Close/Trading Halt Risk Member  
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 GME and may incur substantial losses. If there is a significant intra-day market event and/or GME 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.
T-REX 2X LONG GME DAILY TARGET ETF | Equity Securities Risk Member  
Prospectus [Line Items]  
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 GME does not provide leveraged exposure to GME and, as a result, if the Fund invests directly in common stock of GME to a greater extent, the Fund may not achieve its 200% daily investment objective.
T-REX 2X LONG GME 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 GME 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.

•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.

Risk [Text Block]
Consumer Discretionary Sector Risk. Because companies in the consumer discretionary sector manufacture products and provide discretionary services directly to the consumer, the success of these companies is tied closely to the performance of the overall domestic and international economy, including the functioning of the global supply chain, interest rates, competition, and consumer confidence. Success depends heavily on disposable household income and

Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on a company’s profitability. Changes in demographics and consumer tastes also can affect the demand for, and success of, consumer discretionary products in the marketplace.

Risk [Text Block] Video Gaming and eSports Companies Risk. The Fund will be sensitive to, and its performance may depend to a greater extent on, the overall condition of video gaming and eSports companies. Video gaming and eSports companies face intense competition, both domestically and internationally, may have limited product lines, markets, financial resources, or personnel, may have products that face rapid obsolescence, and are heavily dependent on the protection of patent and intellectual property rights. Video gaming companies may be dependent on one or a small number of product or product franchises for a significant portion of their revenue and profits. They may also be subject to shifting consumer preferences, including preferences with respect to gaming console platforms, and changes in consumer discretionary spending. Such factors may adversely affect the profitability and value of video gaming and eSports companies. Video gaming companies are also subject to increasing regulatory constraints, particularly with respect to cybersecurity and privacy, and may be subject to sophisticated intellectual property infringement schemes and piracy efforts. Video gaming and eSports companies may have significant exposure to the following industries, and therefore may be subject to the risks associated with such industries.

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 HOOD 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 HOOD’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 HOOD during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how HOOD 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) HOOD volatility; b) HOOD 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 HOOD. 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 HOOD volatility and HOOD performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to HOOD; (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 HOOD.

During periods of higher HOOD volatility, the volatility of HOOD may affect the Fund’s return as much as, or more than, the return of HOOD. 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 HOOD 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 HOOD provided no return over a one-year period during which HOOD 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 HOOD’s return is flat. For instance, if HOOD’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 HOOD 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 HOOD. 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.

T-REX 2X LONG HOOD 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 HOOD 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 HOOD, 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 HOOD 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 HOOD does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with HOOD 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 HOOD 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.

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, 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.

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 HOOD, 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 HOOD 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 HOOD 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 HOOD at the market close on the first trading day and the value of HOOD at the time of purchase. If HOOD gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if HOOD 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 HOOD.

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 HOOD 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 HOOD and therefore achieve its daily leveraged investment objective. The Fund’s exposure to HOOD is impacted by HOOD’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to HOOD at the end of each day. The possibility of the Fund being materially over- or under-exposed to HOOD increases on days when HOOD 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) HOOD. 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 HOOD. 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 HOOD. 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 HOOD. Any of these factors could decrease the correlation between the performance of the Fund and HOOD 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 HOOD 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.

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 HOOD. 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 HOOD value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the HOOD. Under such circumstances, the market for HOOD 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 HOOD and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for HOOD 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 HOOD 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 HOOD and may incur substantial losses. If there is a significant intra-day market event and/or HOOD 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 HOOD does not provide leveraged exposure to HOOD and, as a result, if the Fund invests directly in common stock of HOOD 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 HOOD 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

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.

Prospectus [Line Items]  
Risk [Text Block] 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 HOOD DAILY TARGET ETF | ETF Risks, Costs Of Buying Or Selling Shares Member

Risk [Text Block] 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 HOOD DAILY TARGET ETF | ETF Risks, 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. 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.
T-REX 2X LONG HOOD DAILY TARGET ETF | Financials Sector Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Financials Sector Risk. Performance of companies in the financial sector may be materially impacted by many factors, including but not limited to, government regulations, economic conditions, credit rating downgrades, changes in interest rates and decreased liquidity in credit markets. Profitability of these companies is largely dependent on the availability and cost of capital and can fluctuate significantly when interest rates change. Credit losses resulting from financial difficulties of borrowers also can negatively impact the sector. These companies are also subject to substantial government regulation and intervention, which may adversely impact the scope of their activities, the prices they can charge, the amount of capital they must maintain, and potentially, their size. Government regulation may change frequently and may have significant adverse consequences for financial companies, including effects that are not intended by such regulation. The impact of more stringent capital requirements, or recent or future regulation in various countries on any individual financial company or of the financial sector as a whole, cannot be predicted. The financials sector is also a target for cyber-attacks and may experience technology malfunctions and disruptions, which have occurred more frequently in recent years.

T-REX 2X LONG HOOD 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 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 impact 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 impact 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, 2025 was 48.06%. KTOS’s annualized daily volatility rates were as follows:

2021    43.06%
2022    54.70%
2023    41.86%
2024    41.05%
2025    56.80%

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

KTOS’s annualized performance for the five-year period ended December 31, 2025 was 22.56%. 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 $134.00 on January 20, 2026 and the 52-week low stock price for KTOS is $31.48, which occurred on April 21, 2025. 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.

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, 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.
T-REX 2X LONG KTOS 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 KTOS and therefore achieve its daily leveraged investment objective. 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.

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 | 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 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.

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 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.

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.

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]
ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.

•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.

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.

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.

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 MICROSOFT 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 MSFT’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 MSFT during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how MSFT 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) MSFT volatility; b) MSFT 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 MSFT. 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 MSFT volatility and MSFT performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to MSFT; (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 MSFT.

During periods of higher MSFT volatility, the volatility of MSFT may affect the Fund’s return as much as, or more than, the return of MSFT. 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 MSFT 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 MSFT provided no return over a one-year period during which MSFT 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 MSFT’s return is flat. For instance, if MSFT’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 MSFT 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 MSFT. 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.

T-REX 2X LONG MICROSOFT 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 MSFT 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 MSFT, 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 MSFT 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 MSFT does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with MSFT 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.
T-REX 2X LONG MICROSOFT 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 MICROSOFT 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 MSFT, 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 MSFT 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 MICROSOFT 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 MSFT at the market close on the first trading day and the value of MSFT at the time of purchase. If MSFT gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if MSFT 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 MSFT.

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 MICROSOFT 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 MSFT and therefore achieve its daily leveraged investment objective. The Fund’s exposure to MSFT is impacted by MSFT’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to MSFT at the end of each day. The possibility of the Fund being materially over- or under-exposed to MSFT increases on days when MSFT 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) MSFT. 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 MSFT. 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 MSFT. 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 MSFT. Any of these factors could decrease the correlation between the performance of the Fund and MSFT 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.

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.

The Fund will be concentrated in the industry to which Microsoft Corporation is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Microsoft Corp. is assigned). A portfolio concentrated in a particular industry may present more risks than a portfolio broadly diversified over several industries.

•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.

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.

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 MSFT. 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 MSFT value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the MSFT. Under such circumstances, the market for MSFT 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 MSFT and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for MSFT 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 MSFT 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 MSFT and may incur substantial losses. If there is a significant intra-day market event and/or MSFT 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 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 MSFT does not provide leveraged exposure to MSFT and, as a result, if the Fund invests directly in common stock of MSFT 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.

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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Risk [Text Block]
Mega-Capitalization Company Risk. Investments in mega-capitalization companies may involve certain risks. Although mega-cap companies are typically well-established and may have substantial financial resources, broad product lines, and diversified operations, they may be less able to respond quickly to changes in market conditions, technological developments, or shifts in consumer preferences. As a result, such companies may experience slower growth rates compared to smaller or mid-sized companies.

In addition, mega-cap companies may be subject to increased regulatory scrutiny, as well as heightened exposure to global economic, political, and geopolitical risks due to their multinational operations. Their size and market prominence may make it more difficult to achieve significant growth, particularly during periods of economic expansion. While securities of mega-cap companies may be less volatile than those of smaller companies, they may underperform other segments of the market, which could adversely affect the Fund’s investment returns.
T-REX 2X LONG MICROSOFT 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.

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, 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.

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. As of the date of this prospectus, in addition to the risks associated with companies in the technology sector, Microsoft Corp. faces risks associated with competition in the technology sector and among platform-based ecosystems, including its cloud-based services; the evolution of its business, including the development of its new products and acquisitions, joint ventures and strategic alliances; cybersecurity, data privacy and platform abuses; operations, including excessive outages, data losses or disruptions of online services; quality or supply problems; legal, regulatory and litigation risks; and the ability to attract and retain talented employees.

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 RBLX 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 RBLX’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 RBLX during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how RBLX 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) RBLX volatility; b) RBLX 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 RBLX. 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 RBLX volatility and RBLX performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to RBLX; (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 RBLX.

During periods of higher RBLX volatility, the volatility of RBLX may affect the Fund’s return as much as, or more than, the return of RBLX. 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 RBLX 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 RBLX provided no return over a one-year period during which RBLX 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 RBLX’s return is flat. For instance, if RBLX’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 RBLX 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 RBLX. 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.

RBLX’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 74.24%. RBLX’s annualized daily volatility rates were as follows:

2021    103.01%
2022    96.06%
2023    61.56%
2024    49.23%
2025    48.81%

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

RBLX’s annualized performance for the five-year period ended December 31, 2025 was 12.99%. Historical volatility and performance are not indications of what RBLX volatility and performance will be in the future. The public trading price of RBLX’s common stock is volatile compared to the market. The public trading price of RBLX’s common stock has been volatile, similar to other newly public companies that have historically experienced highly volatile trading prices. The public trading price of RBLX’s common stock may fluctuate in response to various factors. By way of example, currently RBLX’s 52-week high stock price was $150.59 on July 31, 2025, and its 52-week low stock price was $51.23 on March 30, 2026. RBLX’s 52-week high and low stock price may change significantly over a short period of time.

Factors that could cause fluctuations in the public trading price of RBLX’s common stock include the following: sales or expectations with respect to sales of shares of RBLX’s common stock by shareholders; price and volume fluctuations in the overall stock market from time to time; volatility in the trading prices and trading volumes of technology stocks; changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular; failure of securities analysts to maintain coverage of RBLX, changes in financial estimates by securities analysts who follow RBLX or our failure to meet these estimates or the expectations of investors; announcements by RBLX or our competitors of new services or platform features; the public’s reaction to press releases, other public announcements, and filings with the SEC; rumors and market speculation involving RBLX’s or other companies in our industry; actual or anticipated changes in RBLX’s results of operations or fluctuations in RBLX’s results of operations; actual or anticipated developments in RBLX’s business, competitors’ businesses, or the competitive landscape generally; developments or disputes concerning intellectual property or other proprietary rights; announced or completed acquisitions of businesses, services, or technologies by RBLX’s or its competitors; any significant change in RBLX’s management or other key personnel and general economic conditions and slow or negative growth of RBLX’s markets.

T-REX 2X LONG RBLX 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 RBLX 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 RBLX, 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 RBLX 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 RBLX does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with RBLX 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.

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, 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.

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.

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 RBLX, 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 RBLX 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.

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 RBLX at the market close on the first trading day and the value of RBLX at the time of purchase. If RBLX gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if RBLX 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 RBLX.

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.

Risk [Text Block]
Daily Correlation Risk. There is no guarantee that the Fund will achieve a high degree of correlation to RBLX and therefore achieve its daily leveraged investment objective. The Fund’s exposure to RBLX is impacted by RBLX’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to RBLX at the end of each day. The possibility of the Fund being materially over- or under-exposed to RBLX increases on days when RBLX 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) RBLX. 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 RBLX. 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 RBLX. 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 RBLX. Any of these factors could decrease the correlation between the performance of the Fund and RBLX 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]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Roblox Corp. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Roblox Corp. 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, RBLX is assigned to the entertainment industry.
•Entertainment Industry Risk. The entertainment industry is highly competitive and relies on consumer spending and the availability of disposable income for success. The prices of the securities of companies in the entertainment industry may fluctuate widely due to competitive pressures, heavy expenses incurred for research and development of products, problems related to bringing products to market, consumer preferences and rapid obsolescence of products. Legislative or regulatory changes and increased government supervision also may affect companies in the entertainment industry.
T-REX 2X LONG RBLX 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 RBLX 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 RBLX. 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 RBLX value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the RBLX. Under such circumstances, the market for RBLX may lack sufficient liquidity for all market participant’' 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 RBLX and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for RBLX and/or Fund may lack sufficient liquidity for all market participant’' 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 RBLX 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 RBLX and may incur substantial losses. If there is a significant intra-day market event and/or RBLX 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 RBLX does not provide leveraged exposure to RBLX and, as a result, if the Fund invests directly in common stock of RBLX 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 RBLX 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

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 SMR 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 SMR’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 impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SMR during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how SMR 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) SMR volatility; b) SMR 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 SMR. 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 SMR volatility and SMR performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to SMR; (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 SMR.

During periods of higher SMR volatility, the volatility of SMR may affect the Fund’s return as much as, or more than, the return of SMR. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of SMR 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 SMR provided no return over a one-year period during which SMR 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 SMR’s return is flat. For instance, if SMR’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 SMR 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 SMR. 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.

SMR’s annualized historical daily volatility rate for the five-year period ended December 31, 2025 was 88.73%. SMR’s annualized daily volatility rates were as follows:

2021    27.42%
2022    47.16%
2023    76.94%
2024    132.43%
2025    113.18%

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

SMR’s annualized performance for the five-year period ended December 31, 2025 was 6.96%. Historical volatility and performance are not indications of what SMR volatility and performance will be in the future. The market price of SMR’s common stock may be volatile and could decline significantly. The price of SMR’s common stock may be more volatile than the markets. Technology stocks have historically experienced high levels of volatility. By way of example, currently, SMR’s 52-week high stock price was $57.42 on October 16, 2025, and its 52-week low stock price was $8.85 on April 13, 2026. SMR’s high and low stock price may change significantly over a short period of time.

T-REX 2X Long SMR 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 SMR 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 SMR, 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 SMR 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 SMR does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SMR 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 SMR 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.

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, 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.

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 SMR, 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 SMR 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 SMR 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 SMR at the market close on the first trading day and the value of SMR at the time of purchase. If SMR gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if SMR 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 SMR.

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 SMR 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 SMR and therefore achieve its daily leveraged investment objective. The Fund’s exposure to SMR is impacted by SMR’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to SMR at the end of each day. The possibility of the Fund being materially over- or under-exposed to SMR increases on days when SMR 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) SMR. 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 SMR. 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 SMR. 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 SMR. Any of these factors could decrease the correlation between the performance of the Fund and SMR 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]
Industry Concentration Risk. The Fund will be concentrated in the industry to which NuScale Power Corporation is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which NuScale Power 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, SMR is assigned to the specialty industrial machinery industry.

•Specialty Industrial Machinery Industry Risk. The specialty industrial machinery industry is inherently sensitive to fluctuations in global economic conditions, as demand is closely tied to capital investment cycles across a range of end-user sectors, including automotive, aerospace, energy, construction, and advanced manufacturing. During economic downturns, businesses in these sectors typically reduce or defer capital expenditures, leading to a contraction in orders for specialized machinery. This cyclicality can result in significant revenue volatility across the industry. Additionally, shifts in interest rates, commodity prices, or government infrastructure spending can either accelerate or suppress demand, creating forecasting challenges and operational risk for machinery manufacturers and suppliers.
T-REX 2X Long SMR 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 SMR 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 SMR. 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 SMR value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the SMR. Under such circumstances, the market for SMR may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities financial instruments and the Fund's
transactions could exacerbate the price changes of SMR and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for SMR 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 SMR 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 SMR and may incur substantial losses. If there is a significant intra-day market event and/or SMR 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 SMR does not provide leveraged exposure to SMR and, as a result, if the Fund invests directly in common stock of SMR 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 SMR 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:
•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.

•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.

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.

In addition to the risks associated generally with operating companies, SMR 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 SMR common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of SMR’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.

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 SNOW 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 SNOW’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 SNOW during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how SNOW 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) SNOW volatility; b) SNOW 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 SNOW. 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 SNOW volatility and SNOW performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect to SNOW; (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 SNOW.

During periods of higher SNOW volatility, the volatility of SNOW may affect the Fund’s return as much as, or more than, the return of SNOW. 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 SNOW 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 SNOW provided no return over a one-year period during which SNOW 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 SNOW’s return is flat. For instance, if SNOW’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 SNOW 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 SNOW. 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.

SNOW’s annualized performance for the five-year period ended December 31, 2025 was -4.86%. Historical volatility and performance are not indications of what SNOW volatility and performance will be in the future. SNOW’s stock price may be volatile, and may fluctuate more than the market. By way of example, currently, SNOW's 52-week high stock price was $280.67 on November 3, 2025, and its 52-week low stock price was $118.30 on April 10, 2026. SNOW’s high and low stock price may change significantly over a short period of time.

The market price of SNOW’s common stock has been and may continue to be highly volatile and may fluctuate or decline substantially as a result of a variety of factors, including: actual or anticipated fluctuations in SNOW’s financial condition or results of operations; variance in SNOW’s actual or projected financial performance from expectations of securities analysts; changes in the pricing or consumption of SNOW’s platform; updates to SNOW’s projected operating and financial results; changes in laws or regulations applicable to SNOW’s business; announcements by SNOW or our competitors of significant business developments, acquisitions, investments, or new offerings; rumors and market speculation involving SNOW or other companies in the industry; changes in senior management or key personnel; fluctuations in company valuations, particularly valuations of high-growth or cloud companies, perceived to be comparable to SNOW; and changes in the anticipated future size and growth rate of SNOW’s market.

T-REX 2X LONG SNOW 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 SNOW 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 SNOW, 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 SNOW 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 SNOW does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SNOW 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 SNOW 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.

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, 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 SNOW 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 SNOW, 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 SNOW 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 SNOW 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 SNOW 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 SNOW at the market close on the first trading day and the value of SNOW at the time of purchase. If SNOW gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if SNOW 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 SNOW.
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 SNOW 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 SNOW and therefore achieve its daily leveraged investment objective. The Fund’s exposure to SNOW is impacted by SNOW’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to SNOW at the end of each day. The possibility of the Fund being materially over- or under-exposed to SNOW increases on days when SNOW 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) SNOW. 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 SNOW. 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 SNOW. 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 SNOW. Any of these factors could decrease the correlation between the performance of the Fund and SNOW 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 Trust, the Fund and any affiliate are not responsible for the performance of Snowflake Inc. and make no representation as to the performance of SNOW.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Snowflake Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Snowflake 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, SNOW is assigned to the information technology sector and the IT services industry.
T-REX 2X LONG SNOW 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 SNOW 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 SNOW. 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 SNOW value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the SNOW. Under such circumstances, the market for SNOW 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 SNOW and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for SNOW 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 SNOW and correlated derivative instruments.
T-REX 2X LONG SNOW DAILY TARGET ETF | Early Close/Trading Halt Risk Member  
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 SNOW and may incur substantial losses. If there is a significant intra-day market event and/or SNOW 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.
T-REX 2X LONG SNOW DAILY TARGET ETF | Equity Securities Risk Member  
Prospectus [Line Items]  
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 SNOW does not provide leveraged exposure to SNOW and, as a result, if the Fund invests directly in common stock of SNOW to a greater extent, the Fund may not achieve its 200% daily investment objective.
T-REX 2X LONG SNOW 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 SNOW 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Risk [Text Block]
Information Technology Sector 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 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 impact 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 impact 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, 2025 was 67.97%. TTD’s annualized daily volatility rates were as follows:

2021    70.43%
2022    87.59%
2023    56.00%
2024    42.17%
2025    74.62%

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

TTD’s annualized performance for the five-year period ended December 31, 2025 was -13.87%. 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 $91.45 on August 7, 2025 and the 52-week low stock price for TTD is $19.74, which occurred on April 9, 2026. 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.

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, 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.

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 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.

Industry Concentration Risk. The Fund will be concentrated in the industry to which Trade Desk, Inc.is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Trade Desk, 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, TTD is assigned to the advertising and marketing industry.

•Advertising and Marketing Industry Risk.    The advertising and marketing industry is highly competitive and sensitive to changes in economic conditions, client spending, and evolving media consumption patterns. Companies in this sector face risks from fluctuations in advertising budgets, which are often reduced during economic downturns, as well as increasing competition from digital platforms and in-house marketing capabilities of clients. Rapid technological change, including shifts toward programmatic advertising, data analytics, and social media, requires continuous investment and adaptation. In addition, regulatory requirements related to data privacy, consumer protection, and digital tracking may limit targeting capabilities and increase compliance costs. Dependence on key clients, reputational risks, and the effectiveness of marketing campaigns further contribute to revenue volatility. These factors collectively may materially affect the performance and profitability of businesses in the advertising and marketing industry.

T-REX 2X LONG TTD 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 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.

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 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.

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 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.
T-REX 2X LONG TTD 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 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Risk [Text Block] 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.

Prospectus [Line Items]  
Risk [Text Block] 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.

T-REX 2X LONG TTD 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 INVERSE CRCL 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 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 CRCL’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are inverse and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRCL during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how CRCL 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) CRCL volatility; b) CRCL performance; c) period of time; d) financing rates associated with inverse exposure; e) other Fund expenses; and f) dividends or interest paid with respect CRCL. 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 CRCL volatility and CRCL performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect CRCL; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain inverse 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 CRCL.

During periods of higher CRCL volatility, the volatility of CRCL may affect the Fund’s return as much as, or more than, the return of CRCL. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRCL 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 17.1% if CRCL provided no return over a one-year period during which CRCL 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 CRCL’s return is flat. For instance, if CRCL’s annualized volatility is 100%, the Fund would be expected to lose 95% 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 CRCL 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 CRCL. 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 Inverse Correlation Risk” below.

CRCL’s annualized historical daily volatility rate for the one-year period ended December 31, 2025 was 252.81%. CRCL’s annualized daily volatility rates were as follows:
 
2025      411.67%
 
Volatility for a shorter period of time may have been substantially higher.
 
CRCL’s annualized performance for the one-year period ended December 31, 2025 was 252.81%. Historical volatility and performance are not indications of what CRCL volatility and performance will be in the future. CRCL’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 CRCL is $298.99 on June 23, 2025 and the 52-week low stock price for CRCL is $49.90, which occurred on February 5, 2026. CRCL’s 52-week high and low stock price may change significantly over a short period of time.

T-REX 2X INVERSE CRCL 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.
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, 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.

Put Options. The use of put 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, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, 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 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 INVERSE CRCL 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 inverse 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 inverse investment objective or may decide to change its inverse 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 CRCL, 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 CRCL 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 INVERSE CRCL DAILY TARGET ETF | Intra-Day Investment Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Intra-Day Investment Risk. The Fund seeks 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 CRCL at the market close on the first trading day and the value of CRCL at the time of purchase. If CRCL loses value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CRCL rises, 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 CRCL.

If there is a significant intra-day market event and/or CRCL experiences 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 prior to the close of trading on the Exchange and experience significant losses.

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]
Industry Concentration Risk. The Fund will be concentrated in the industry to which Circle Internet Group, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide exposure to the industry to which Circle Internet Group, 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, CRCL is assigned to the capital markets industry.

•Capital Markets Risk. The capital markets industry includes companies that facilitate the issuance, buying, and selling of financial securities and other investments, such as broker-dealers, investment banks, asset managers, securities exchanges, and financial data providers. These companies may be adversely affected by market volatility, reduced trading activity, changes in interest rates, or a decline in the value of assets under management. Their profitability can be sensitive to economic and market conditions, regulatory changes, competition, and technological disruption. In addition, capital markets companies are subject to operational risks, including settlement failures, cybersecurity incidents, and compliance costs. Adverse developments in the capital markets sector could negatively impact the value of the Fund’s investments in such companies.
T-REX 2X INVERSE CRCL 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 INVERSE CRCL 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 CRCL. 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 CRCL value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in CRCL. Under such circumstances, the market for CRCL 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 CRCL and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for certain securities in CRCL 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 CRCL 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 CRCL and may incur substantial losses. If there is a significant intra-day market event and/or the securities of the Index experience a significant 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. To the extent that the Fund engages in short sales of the common stock of CRCL, such short sales do not provide leveraged exposure to CRCL and, as a result, the Fund may not achieve its -200% daily investment objective.

Prospectus [Line Items]  
Risk [Text Block]
Cash Transaction Risk. Unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally for in-kind securities, because of the nature of the financial instruments held by the Fund. As a result, the Fund is not expected to be tax efficient and will incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than other funds that primarily effect 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 INVERSE CRCL 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

CRCL 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, CRCL faces risks unique due to its business model. CRCL, which operates under the brand name CRCL, is a global financial technology company that specializes in digital currencies and blockchain technology. CRCL is best known for issuing the stablecoin USDC, a digital currency pegged to the U.S. dollar. CRLC also provides various financial and technology services to businesses and developers, enabling them to integrate stablecoins and blockchain technology into their operations. CRCL operations subjects it to the following risks:

•Interest Rate Risk: CRCL’s revenue model heavily relies on the interest earned from reserves that back its USDC stablecoin, which are primarily held in short-term U.S. Treasury bills. A decline in interest rates could significantly reduce Circle's income and impact its profitability.
•Regulatory Uncertainty: The cryptocurrency regulatory landscape is volatile and evolving, with varying standards across different jurisdictions. Stricter regulations, increased oversight, or changes in how regulatory bodies interpret and apply existing laws could hinder CRCL’s growth or pose threats to its business model. While certain
legislative and regulatory initiatives aim to bring more regulatory clarity, stricter capital requirements or limits on interest income could negatively impact CRCL’s margins.
•Competitive Pressure: The stablecoin market is becoming increasingly competitive, with rivals and potential entrants from traditional banks exploring stablecoin offerings. This could erode CRCL’s market share and impact its revenue and profitability.
•Macroeconomic Volatility: Broad economic factors, such as shifts in interest rates or volatility in the cryptocurrency market, can affect CRCL’s financial performance. A pivot to lower interest rates could reduce interest income from reserves, while a crypto bear market could shrink USDC's circulation and impact revenue.
•Dependence on Partnerships: While CRCL has expanded its product offerings and revenue streams, it still relies on significant partnerships for the distribution and adoption of USDC. If these partnerships change or end, it could impact CRCL’s distribution costs and reserve income.
•De-pegging Risk: While USDC is designed to be redeemable 1:1 for U.S. dollars, there is a risk of a "de-peg," where the token could trade below $1 on third-party platforms. This could be triggered by events like a run on a bank holding CRCL’s assets.
•Cybersecurity Risks: CRCL’s reliance on third-party systems and the increasing sophistication of cyberattacks expose the company to potential security breaches that could affect its operations, data, and reputation. 
The trading price of CRCL common stock is likely to be volatile. Additionally, CRCL’s common stock 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. CRCL is a highly dynamic company, and its operations, including its products and services, may change.

These companies may be adversely affected by market volatility, reduced trading activity, changes in interest rates, or a decline in the value of assets under management. Their profitability can be sensitive to economic and market conditions, regulatory changes, competition, and technological disruption. In addition, capital markets companies are subject to operational risks, including settlement failures, cybersecurity incidents, and compliance costs. Adverse developments in the capital markets sector could negatively impact the value of the Fund’s investments in such companies.
T-REX 2X INVERSE CRCL DAILY TARGET ETF | Shorting Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Shorting Risk. A short position is a financial transaction in which an investor sells an asset that the investor does not own. In such a transaction, an investor’s short position appreciates when a reference asset falls in value. By contrast, the short position loses value when the reference asset’s value increases. Because historically most assets have risen in value over the long term, short positions are expected to depreciate in value. Accordingly, short positions may be riskier and more speculative than traditional investments. In addition, any income, dividends, or payments by reference assets in which the Fund has a short position will impose expenses on the Fund that reduce returns.

The Fund will obtain short exposure through the use of swap agreements, purchased put options, and physical short sales of CRCL. To the extent that the Fund obtains short exposure from derivatives, the Fund may be exposed to heightened volatility or limited liquidity related to the reference asset of the underlying short position, which will adversely impact the Fund’s ability to meet its investment objective or adversely impact its performance. If the Fund were to experience this volatility or decreased liquidity, the Fund may be required to obtain short exposure through alternative investment strategies that may be less desirable or more costly to implement. If the reference asset underlying the short position is thinly traded or has a limited market, there may be a lack of available securities or counterparties for the Fund to enter into a short position or obtain short exposure from a derivative. To the extent the Fund engages in physical short sales, the Fund is subject to the risk that the price of the security will increase between the date of the short sale and the date on which the Fund replaces the security, the Fund will experience a loss, which is theoretically unlimited. In addition, physical short sales do not provide -200% exposure to CRCL and, as a result, if the Fund engages in physical short sales to a greater extent, the Fund may not achieve its -200% daily investment objective.

Risk [Text Block]
Daily Inverse Correlation Risk. There is no guarantee that the Fund will achieve a high degree of inverse correlation to CRCL and therefore achieve its daily inverse investment objective. The Fund’s exposure to CRCL is impacted by CRCL’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to CRCL at the end of each day. The
possibility of the Fund being materially over- or under-exposed to CRCL increases on days when CRCL 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 inverse 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) CRCL. 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 inverse correlation with CRCL. 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 CRCL. 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 CRCL. Any of these factors could decrease the inverse correlation between the performance of the Fund and CRCL and may hinder the Fund’s ability to meet its daily inverse investment objective on or around that day.

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 INVERSE CRWV 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 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 CRWV’s performance, before fees and expenses. Compounding affects all investments, but has a more significant impact on funds that are inverse and that rebalance daily and becomes more pronounced as volatility and holding periods increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRWV during the shareholder’s holding period of an investment in the Fund.

The chart below provides examples of how CRWV 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) CRWV volatility; b) CRWV performance; c) period of time; d) financing rates associated with inverse exposure; e) other Fund expenses; and f) dividends or interest paid with respect CRWV. 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 CRWV volatility and CRWV performance over a one-year period. Performance shown in the chart assumes that: (i) no dividends were paid with respect CRWV; (ii) there were no Fund expenses; and (iii) borrowing/lending rates (to obtain inverse 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 CRWV.

During periods of higher CRWV volatility, the volatility of CRWV may affect the Fund’s return as much as, or more than, the return of CRWV. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of CRWV 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 17.1% if CRWV provided no return over a one-year period during which CRWV 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 CRWV’s return is flat. For instance, if CRWV’s annualized volatility is 100%, the Fund would be expected to lose 95% 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 CRWV 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 CRWV. 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 Inverse Correlation Risk” below.

CRWV’s annualized historical daily volatility rate for the one-year period ended December 31, 2025 was 124.16%. CRWV’s annualized daily volatility rates were as follows:
 
2025       124.16%
 
Volatility for a shorter period of time may have been substantially higher.
 
CRWV’s annualized performance for the period ended December 31, 2025 was 114.23%. The market prices of CRWV’s common stock are subject to fluctuations due both to factors affecting market prices for publicly traded equity securities generally and to factors affecting CRWV’s common stock. CRWV’s stock price may be more volatile than the market. Market prices of CRWV’s common stock have been volatile at times in the past, and may be volatile in the future. By way of example, currently, CRWV's 52-week high stock price was $187.00 on June 20, 2025, and its 52-week low stock price was $33.52 on April 21, 2025. CRWV’s high and low stock price may change significantly over a short period of time.

T-REX 2X INVERSE CRWV 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.

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, 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.

Put Options. The use of put 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, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, 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 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.

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 inverse 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 inverse investment objective or may decide to change its inverse 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 CRWV, 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 CRWV 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 INVERSE CRWV DAILY TARGET ETF | Intra-Day Investment Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Intra-Day Investment Risk. The Fund seeks 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 CRWV at the market close on the first trading day and the value of CRWV at the time of purchase. If CRWV loses value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if CRWV rises, 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 CRWV.

If there is a significant intra-day market event and/or CRWV experiences 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 prior to the close of trading on the Exchange and experience significant losses.

•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.

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 INVERSE CRWV 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 CRWV. 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 CRWV value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in CRWV. Under such circumstances, the market for CRWV 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 CRWV and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for certain securities in CRWV 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 CRWV 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 CRWV and may incur substantial losses. If there is a significant intra-day market event and/or the securities of the Index experience a significant 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. To the extent that the Fund engages in short sales of the common stock of CRWV, such short sales do not provide leveraged exposure to CRWV and, as a result, the Fund may not achieve its -200% daily investment objective.
T-REX 2X INVERSE CRWV DAILY TARGET ETF | Cash Transaction Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Cash Transaction Risk. Unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally for in-kind securities, because of the nature of the financial instruments held by the Fund. As a result, the Fund is not expected to be tax efficient and will incur brokerage costs related to buying and selling securities to achieve its investment objective thus incurring additional expenses than other funds that primarily effect 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 INVERSE CRWV 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.

ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks:

•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.

•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.

Risk [Text Block] CRWV 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, CRWV 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 CRWV common stock historically has been and is likely to continue to be volatile. Additionally, a large proportion of CRWV’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. CRWV is a highly dynamic company, and its operations, including its products and services, may change.

Risk [Text Block]
Information Technology Sector 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.
T-REX 2X INVERSE CRWV DAILY TARGET ETF | Shorting Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Shorting Risk. A short position is a financial transaction in which an investor sells an asset that the investor does not own. In such a transaction, an investor’s short position appreciates when a reference asset falls in value. By contrast, the short position loses value when the reference asset’s value increases. Because historically most assets have risen in value over the long term, short positions are expected to depreciate in value. Accordingly, short positions may be riskier and more speculative than traditional investments. In addition, any income, dividends, or payments by reference assets in which the Fund has a short position will impose expenses on the Fund that reduce returns.

The Fund will obtain short exposure through the use of swap agreements, purchased put options, and physical short sales of CRWV. To the extent that the Fund obtains short exposure from derivatives, the Fund may be exposed to heightened volatility or limited liquidity related to the reference asset of the underlying short position, which will adversely impact the Fund’s ability to meet its investment objective or adversely impact its performance. If the Fund were to experience this volatility or decreased liquidity, the Fund may be required to obtain short exposure through alternative investment strategies that may be less desirable or more costly to implement. If the reference asset underlying the short position is thinly traded or has a limited market, there may be a lack of available securities or counterparties for the Fund to enter into a short position or obtain short exposure from a derivative. To the extent the Fund engages in physical short sales, the Fund is subject to the risk that the price of the security will increase between the date of the short sale and the date on which the Fund replaces the security, the Fund will experience a loss, which is theoretically unlimited. In addition, physical short sales do not provide -200% exposure to CRWV and, as a result, if the Fund engages in physical short sales to a greater extent, the Fund may not achieve its -200% daily investment objective.
T-REX 2X INVERSE CRWV DAILY TARGET ETF | Daily Inverse Correlation Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Daily Inverse Correlation Risk. There is no guarantee that the Fund will achieve a high degree of inverse correlation to CRWV and therefore achieve its daily inverse investment objective. The Fund’s exposure to CRWV is impacted by CRWV’s movement. Because of this, it is unlikely that the Fund will be perfectly exposed to CRWV at the end of each day. The possibility of the Fund being materially over- or under-exposed to CRWV increases on days when CRWV 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 inverse 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) CRWV. 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 inverse correlation with CRWV. 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 CRWV. 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 CRWV. Any of these factors could decrease the inverse correlation between the performance of the Fund and CRWV and may hinder the Fund’s ability to meet its daily inverse investment objective on or around that day.

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.
