Objective [Heading] rr_ObjectiveHeading Investment Objective
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock

The Fund seeks daily investment results, before fees and expenses, of 200% of the daily performance of COIN. The Fund does not seek to achieve its stated investment objective for a period of time different than a trading day.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. As of the date of this Prospectus, the Fund has not yet commenced operations and therefore does not have any portfolio turnover information available.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or redeem all of your shares at the end of those periods. The example also assumes that your investment has a five percent (5%) return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to COIN equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on COIN or by investing directly in the common stock of COIN. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in COIN common stock based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument. Direct investments in common stock of COIN is typically less efficient than the use of swap agreements because direct investments in common stock do not provide leveraged returns. This may result in the Fund not achieving its 200% daily investment objective.

The Fund will enter into one or more swap agreements with financial institutions whereby the Fund and the financial institution will agree to exchange the return earned on an investment by the Fund in COIN that is equal, on a daily basis, to 200% of the value of the Fund’s net assets. If the Adviser determines to use call options, the Fund will purchase exchange traded call options, including “FLEX Options.” Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price. Flexible Exchange® Options (“FLEX Options”) are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The FLEX Options are listed on the Chicago Board Options Exchange. The Fund may take delivery of the underlying security (COIN) if it chooses to exercise a call option and either hold or sell the security in the secondary markets.

The Adviser attempts to consistently apply leverage to obtain COIN exposure for the Fund equal to 200% of the value of its net assets and expects to rebalance the Fund’s holdings daily to maintain such exposure. As a result of its investment strategies, the Fund will be concentrated in the industry to which COIN is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which COIN is assigned). As of the date of this prospectus, COIN is assigned to the financial sector and the capital markets industry.

The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of COIN. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to COIN is consistent with the Fund’s investment objective. The impact of COIN’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of COIN has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the price of COIN has fallen on a given day, net assets of the Fund should

fall, meaning the Fund’s exposure will need to be reduced. This daily rebalancing typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality (investment grade) credit ratings, and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality (investment grade) credit profiles, including U.S. government securities and repurchase agreements.

Generally, the Fund pursues its investment objective regardless of market conditions and does not generally take defensive positions. If the Fund’s underlying security moves more than 50% on a given trading day in a direction adverse to the Fund, the Fund’s investors would lose all of their money.

The terms “daily,” “day,” and “trading day,” refer to the period from the close of the markets on one trading day to the close of the markets on the next trading day. The Fund is “non-diversified,” under the Investment Company Act of 1940, as amended. Additionally, the Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval.

Coinbase Global, Inc. operates as a secure hosted cryptocurrency exchange platform. COIN is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Information provided to or filed with the Securities and Exchange Commission by Coinbase Global, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-40289 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Coinbase Global, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of the date of this prospectus, COIN is assigned to the financial sector and the capital markets industry.

The Fund has derived all disclosures contained in this document regarding Coinbase Global, Inc. from the publicly available documents described above. Neither the Fund, the Trust, the Adviser nor any affiliate has participated in the preparation of such documents. Neither the Fund, the Trust, the Adviser nor any affiliate makes any representation that such publicly available documents or any other publicly available information regarding Coinbase Global, Inc. is accurate or complete. Furthermore, the Fund cannot give any assurance that all events occurring prior to the date of the prospectus (including events that would affect the accuracy or completeness of the publicly available documents described above) that would affect the trading price of COIN have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Coinbase Global, Inc. could affect the value of the Fund’s investments with respect to COIN and therefore the value of the Fund.

Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the underlying security over the same period. The Fund will lose money if the underlying security performance is flat over time, and as a result of daily rebalancing, the underlying security’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying security’s performance increases over a period longer than a single day.

The Fund may enter into swap agreements with a limited number of counterparties. If the underlying security has a dramatic move in price that causes a material decline in the Fund’s NAV over certain stated periods agreed to by the Fund and the counterparty, the terms of a swap agreement between a Fund and its counterparty may permit the counterparty to immediately close out all swap transactions with the Fund. 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.

T-REX 2X LONG COIN DAILY TARGET ETF | Risk Nondiversified Status [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 COIN DAILY TARGET ETF | Effects of Compounding and Market Volatility Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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

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

During periods of higher COIN volatility, the volatility of COIN may affect the Fund’s return as much as, or more than, the return of COIN. 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 COIN 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 COIN provided no return over a one-year period during which COIN 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 COIN’s return is flat. For instance, if COIN’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 COIN 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 COIN. The table below is not a representation of the Fund’s actual returns, which may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Daily Correlation Risk” below.

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

COIN’s annualized performance for the five-year period ended December 31, 2024 was (0.18)%. Historical volatility and performance are not indications of what COIN volatility and performance will be in the future. The market price of COIN’s common stock may be volatile and could decline significantly. The price of COIN’s common stock may be more volatile than the markets. Technology stocks have historically experienced high levels of volatility. By way of example, currently, COIN’s 52-week high stock price was $349.75, and its 52-week low stock price was $142.58. COIN’s high and low stock price may change significantly over a short period of time.

Factors which could contribute to the volatility of COIN’s common stock include: overall performance of the equity markets or publicly-listed financial services and technology companies; COIN’s actual or anticipated performance and the operating performance of its competitors; changes in the projected operational and financial results COIN provides to the public or its failure to meet those projections; failure of securities analysts to initiate or maintain coverage of COIN, changes in financial estimates by securities analysts who follow COIN, or COIN’s failure to meets the estimates; any major change in COIN’s board of directors, management or key personnel; issuance of COINs common stock whether in connection with an acquisition or upon conversion of some or all of COIN’s outstanding 2026 convertible notes; rumors or market speculation involving the crypto economy or COIN or other companies in the industry; the highly volatile nature of the crypto economy and prices of crypto assets; or announcements by COIN’s competitors of significant innovations, new products, services, features, integrations or capabilities, acquisitions, strategic investments, partnerships, joint ventures or capital commitments.

T-REX 2X LONG COIN DAILY TARGET ETF | Leverage Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN 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 COIN, 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 COIN 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 COIN does not lose all of its value. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with COIN 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 COIN DAILY TARGET ETF | Derivatives Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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

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

Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN, 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] rr_RiskTextBlock

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 COIN 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 COIN DAILY TARGET ETF | Intra-Day Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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

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 COIN DAILY TARGET ETF | Daily Correlation Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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

Underlying Security 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.

T-REX 2X LONG COIN DAILY TARGET ETF | Financials Sector Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Financials Sector Risk.    Performance of companies in the financials 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 COIN DAILY TARGET ETF | Industry Concentration Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Industry Concentration Risk.    The Fund will be concentrated in the industry to which Coinbase Global, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Coinbase Global, 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, COIN is assigned to the financial sector and the capital markets industry.

Risk [Text Block] rr_RiskTextBlock

Capital Markets Industry Risk.    Capital Markets companies may be significantly affected by stock and bank trading activity, changes in governmental regulation, continuing increases in price competition, decreases in fees or fee-related business, including investment banking, brokerage, asset management and other servicing fees, fluctuation in interest rates and other factors which could adversely affect financial markets.

T-REX 2X LONG COIN DAILY TARGET ETF | Fixed Income Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN DAILY TARGET ETF | Money Market Instrument Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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.

T-REX 2X LONG COIN DAILY TARGET ETF | Large-Capitalization Company Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN DAILY TARGET ETF | Liquidity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN. 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 COIN value increases or decreases significantly, the Fund may be one of many market participants that are attempting to transact in the COIN. Under such circumstances, the market for COIN may lack sufficient liquidity for all market participants’ trades. Therefore, the Fund may have more difficulty transacting in the securities mountal instruments and the Fund’s transactions could exacerbate the price changes of COIN and may impact the ability of the Fund to achieve its investment objective.

In certain cases, the market for COIN 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 COIN and correlated derivative instruments.

T-REX 2X LONG COIN DAILY TARGET ETF | Early Close/Trading Halt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN and may incur substantial losses. If there is a significant intra-day market event and/or COIN 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 COIN DAILY TARGET ETF | Equity Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN does not provide leveraged exposure to COIN and, as a result, if the Fund invests directly in common stock of COIN to a greater extent, the Fund may not achieve its 200% daily investment objective.

T-REX 2X LONG COIN DAILY TARGET ETF | Cash Transaction Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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 COIN DAILY TARGET ETF | Tax Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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.

T-REX 2X LONG COIN DAILY TARGET ETF | Non-Diversification Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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.

T-REX 2X LONG COIN DAILY TARGET ETF | New Fund Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

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