| Risk [Text Block] | Underlying Security Risks. The Fund invests in options that are based on the share price of SPCX. This subjects the Fund to certain of the same risks as if it owned shares of SPCX, even though it does not. By virtue of the Fund’s investments in options that are based on the value of SPCX, the Fund may also be subject to the following risks:

| 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. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:
|
|||
| Options Contracts [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Options Contracts. The use of options contracts 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 political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Security. 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 such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, 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. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.
|
|||
| Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.
|
|||
| Price Participation Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Price Participation Risk. The Fund employs an investment strategy that includes the sale of call option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security over the Call Period. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security over each Call Period, but has full exposure to any decreases in value experienced by the Underlying Security over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options premiums on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security.
|
|||
| Distribution Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Distribution Risk. The Fund seeks to provide weekly cash distributions. There is no assurance that the Fund will make a distribution in any given week. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the weekly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment. In addition, while the underlying stock may pay dividends, the Fund’s returns will not include any dividends paid by the underlying stock, and any income generated by the Fund may be less than the income generated by a direct investment in the underlying stock.

|
|||
| Call Strategy Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Call Strategy Risks. The path dependency (i.e., the continued use) of the Fund’s call writing strategy will impact the extent that the Fund participates in the positive price returns of the Underlying Security and, in turn, the Fund’s returns, both during the term of the sold call options and over longer time periods. If, for example, each month the Fund were to sell 7% out-of-the-money call options having a one-month term, the Fund’s participation in the positive price returns of the Underlying Security will be capped at 7% in any given month. However, over a longer period (e.g., 5 months), the Fund should not be expected to participate fully in the first 35% (i.e., 5 months x 7%) of the positive price returns of the Underlying Security, or the Fund may even lose money, even if the Underlying Security share price has appreciated by at least that much over such period, if during any month over that period the Underlying Security had a return less than 7%. This example illustrates that both the Fund’s participation in the positive price returns of the Underlying Security and its returns will depend not only on the price of the Underlying Security but also on the path that the Underlying Security takes over time.
Additionally, when implementing the Covered Call Spread Strategy, the use of credit call spreads introduces further complexities and risks. While purchasing a higher-strike call option limits potential losses from the short call position, it also reduces the net premium received, which may result in lower overall returns compared to a stand-alone covered call strategy. If the price of the Underlying Security rises rapidly, the call spread may still cap upside participation, leading to missed profit opportunities. Furthermore, market conditions, such as mispricing between near-the-money and further out-of-the-money options, may impact the effectiveness of the strategy, potentially resulting in lower-than-expected returns or increased losses. The relative pricing of options at different strike levels can vary due to volatility shifts, liquidity constraints, or other market dynamics, adding an additional layer of uncertainty to the Fund’s performance under this strategy.

|
|||
| Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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 [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, 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. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

|
|||
| Management Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective.
|

| Shares May Trade at Prices Other Than NAV [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] |
|
|||
| Trading [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have indirect exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. 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 Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Underlying Security’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.
|
|||
| Economic and Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.
|
|||
| High Portfolio Turnover Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
|
|||
| Inflation Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline.
|
|||
| Liquidity Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.
|
|||
| Money Market Instrument Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | 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. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means.
|
|||
| Operational Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
|
|||
| Single Issuer Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.
|
|||
| Tax Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of options it holds is never 25% of the total value of Fund assets at the close of any quarter. If the Fund’s investments in options were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.
|
|||
| U.S. Government and U.S. Agency Obligations Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.
|
|||
| Risk Lose Money [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. | |||
| Risk Nondiversified Status [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
