Investment Risks |
Feb. 24, 2025 |
|---|---|
| Tuttle Capital TSLA Put Write ETF | Put Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Put Options Risk. Puts are subject to volatile swings in price influenced by changes in the value of the underlying instrument. The price of the Puts sold by the Fund will have imperfect correlation to the returns of the Underlying Security. Although the Fund collects premiums on the Puts it writes, the Fund’s risk of loss if the value of the Underlying Security falls below the strike price and the Puts are exercised as of the Roll Date (i.e., the Fund, as the seller of the Puts, owes the buyer of the Puts) will likely outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price (multiplied by 100) of each option it sells.
|
| Tuttle Capital TSLA Put Write ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as an index, interest rate or inflation rate. Generally, derivatives are sophisticated investments that may pose risks that are different from or greater than those posed by investing directly in the underlying reference asset. For example, the return on a derivative instrument may not correlate with that of its underlying reference asset, and minimal requisite initial investments necessary to purchase derivatives positions may expose the Fund to losses in excess of those amounts. Derivatives also can be volatile and may be less liquid than other investments. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. The Fund expects to use put options to implement its principal investment strategies. Other risks specific to put options, as well as other risks of derivatives, generally, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk, are described in greater detail elsewhere in the Fund’s Prospectus.
|
| Tuttle Capital TSLA Put Write ETF | Limited Upside Return Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Upside Return Risk. The Fund’s put option sales strategy subjects the Fund to an upside limitation on returns to the premiums received from the Put owner. The Fund will only participate in upside price swings of the Underlying Security to the extent that the Put sold by the Fund will not be exercised and the Fund will keep all of the premium paid by the Put owner without having to purchase the Underlying Security from the Put owner. In the event an investor purchases Fund shares between Roll Dates, and the value of the Underlying Security falls to a level near or below the strike price, there may be little or no ability for that investor to experience a gain on an investment in Fund shares until the next Roll Date.
|
| Tuttle Capital TSLA Put Write ETF | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may write FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. Additionally, FLEX Options may be illiquid, and in such cases, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices.
|
| Tuttle Capital TSLA Put Write ETF | Rolling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rolling Risk. The Fund’s investment strategy is subject to risks related to rolling. To the extent the Fund’s portfolio managers are unable to roll the Puts as described in the Fund’s principal investment strategy, the Fund may be unable to achieve its investment objective. In addition, because of the frequency with which the Fund expects to roll option contracts, this risk may be greater than the impact would otherwise be if the Fund experienced less portfolio turnover. The price of options contracts further from expiration may be higher, which can impact the Fund’s returns.
|
| Tuttle Capital TSLA Put Write ETF | Assignment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Assignment Risk. The Puts written by the Fund may be assigned to the Fund at any point prior to the expiration date. Early assignment is more likely when the put option is significantly in the money. Should early assignment occur for a put options position, it would result in the Fund acquiring the assigned shares. Consequently, the value of the Fund’s investment may be temporarily exposed to the full market movement of the Underlying Security and the risks attendant to the Underlying Security (explained more fully below), until these shares are sold off and new options positions are established. The Adviser will generally seek to liquidate the assigned shares and re-establish the options position as soon as possible to ensure gains or losses stemming from early assignments are minimized.
|
| Tuttle Capital TSLA Put Write ETF | Implied Volatility Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Implied Volatility Risk. Upon selling a Put, the Fund gains the amount of premium it receives; however, the Fund also incurs a liability that represents the value of the Put it has sold until the Put is exercised or expires. The value of the Puts in which the Fund invests is partly based on the volatility used by market participants to price such options (i.e., implied volatility). Consequently, increases in the implied volatility of the Puts will cause the value of such options to increase (even if the prices of stocks in the Underlying Security do not change), which will result in a corresponding increase in the liabilities of the Fund under the Puts and thus decrease the Fund’s NAV. The Fund is therefore exposed to implied volatility risk before the Puts expire or are struck at-the-money. The implied volatility of the Puts sold by the Fund may increase due to general market and economic conditions, perceptions regarding the industries of companies included in the Underlying Security, or factors relating to certain of those companies.
|
| Tuttle Capital TSLA Put Write ETF | Transaction Cost Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Transaction Cost Risk. The Fund will pay transaction costs, such as commissions or mark-ups in the bid/offer spread on an option position, when it writes options. Because the Fund “turns over” its option positions every week (or more frequently), it will incur high transaction costs. While the turnover of the option positions sold by the Fund is not deemed “portfolio turnover” for accounting purposes, the economic impact to the Fund is similar to what could occur if the Fund experienced high portfolio turnover (e.g., in excess of 100% per year). The Fund’s high levels of transaction costs may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example thereunder, may affect the Fund’s performance.
|
| Tuttle Capital TSLA Put Write ETF | Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. As with all investments, an investment in the Fund is subject to loss, including the possible loss of the entire principal amount of an investment, over short or long periods of time.
|
| Tuttle Capital TSLA Put Write ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
|
| Tuttle Capital TSLA Put Write ETF | Cash Redemption Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes 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 Fund redeemed shares in kind.
|
| Tuttle Capital TSLA Put Write ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Equity securities may be more volatile than other asset classes, and their market prices may change quickly and without warning. The value of an equity security may decrease as a result of the issuer or due to general industry or market conditions unrelated to the issuer. If the value of the Underlying Security decreases or fluctuates, causing the value of the Underlying Security on the Roll Date to fall below the strike price of the Puts sold by the Fund, the NAV of the Fund will decrease or fluctuate, respectively, as the Puts increase in value to their owners. The Fund may also lose value to the extent that it takes delivery of the Underlying Security and has to sell such Underlying Security at a lower price.
|
| Tuttle Capital TSLA Put Write ETF | Active Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement its investment strategies for the Fund. The success of the Fund’s investment program depends largely on the investment techniques applied by the Adviser. It is possible the investment techniques employed on behalf of the Fund will not produce the desired results.
|
| Tuttle Capital TSLA Put Write ETF | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund may, when the Adviser in its discretion deems appropriate, purchase put and/or call options to hedge against the risk of drastic movements in the price of the Underlying Security and may engage in other various investments or transactions that are designed to hedge a position in the Fund’s portfolio. There is no assurance that these hedging techniques will be effective and such techniques involve costs that may reduce gains or result in losses, which may adversely affect the value of Fund shares.
|
| Tuttle Capital TSLA Put Write ETF | Purchase and Sale Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Purchase and Sale Timing Risk. The Fund has multiple Roll Dates each month and, as a result, no matter when an investor purchases Fund shares, even on a Roll Date, the value of the investor’s investment in the Fund may not be protected against a decline in the value of the Underlying Security and may not benefit from a gain in the value of the Underlying Security. The value of the options written by the Fund is dependent on various factors, including, but not limited to, the value and implied volatility of the Underlying Security. Each of these factors may vary significantly during the period between Roll Dates and affect the Fund’s ability to achieve its investment objective between Roll Dates.
|
| Tuttle Capital TSLA Put Write ETF | Distribution and Return of Capital Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Distribution and Return of Capital Risk. The Fund seeks to provide current monthly income. There is no guarantee that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related record date for the distribution. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.
|
| Tuttle Capital TSLA Put Write ETF | Money Market Instruments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.
|
| Tuttle Capital TSLA Put Write ETF | U.S. Treasury Bills Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Bills Risk. U.S. Treasury bills may differ from other debt securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury bills holdings to decline.
|
| Tuttle Capital TSLA Put Write ETF | ETF Structure Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and is therefore subject to special risks. Such risks include:
|
| Tuttle Capital TSLA Put Write ETF | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Issues Risk. Trading in ETF shares on an exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in the ETF’s shares inadvisable, such as extraordinary market volatility. There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.
|
| Tuttle Capital TSLA Put Write ETF | Market Price Variance Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Price Variance Risk. The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.
|
| Tuttle Capital TSLA Put Write ETF | Authorized Participants ("APs"), Market Makers, and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. ETFs have a limited number of financial institutions that may act as 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 of an ETF may trade at a material discount to NAV and possibly face delisting: () 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.

| Tuttle Capital TSLA Put Write ETF | Costs of Buying or Selling Shares of an ETF [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
|
| Tuttle Capital TSLA Put Write ETF | Industry Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industry Concentration Risk. The Fund will be concentrated in the industry to which Tesla, Inc. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which Tesla, 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, TSLA is assigned to the motor vehicles and passenger car bodies industry.
|
| Tuttle Capital TSLA Put Write ETF | 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 may decline.
|
| Tuttle Capital TSLA Put Write ETF | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk. Interest rate risk is the risk that the value of the Fund’s investments will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term options and debt securities and higher for longer-term options and debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. When interest rates increase, call options generally benefit while put option prices are impacted negatively.
|
| Tuttle Capital TSLA Put Write ETF | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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.
|
| Tuttle Capital TSLA Put Write ETF | Investment Risks of the Underlying Security [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risks of the Underlying Security
|
| Tuttle Capital TSLA Put Write ETF | Tesla, Inc. Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tesla, Inc. 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 and electric and autonomous vehicles and other automotive companies, Tesla, Inc. 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, and product liability claims.
|
| Tuttle Capital TSLA Put Write ETF | Electric and Autonomous Vehicles Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Electric and Autonomous Vehicles Company Risk. Electric and autonomous vehicles companies typically face intense competition and potentially rapid product obsolescence. Many of these companies are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Electric and autonomous vehicles companies are also potential targets for cyberattacks, which can have a materially adverse impact on the performance of these companies. The customers and/or suppliers of electric and autonomous vehicles companies may be concentrated in a particular country, region or industry, including in emerging markets. Any adverse event affecting one of these countries, regions or industries could have a negative impact on electric and autonomous vehicles companies.
|
| Tuttle Capital TSLA Put Write ETF | Automotive Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Automotive Companies Risk. The automotive industry can be highly cyclical, and companies in the industry may suffer periodic operating losses. Automotive companies can be significantly affected by labor relations and fluctuating component prices. Developments in automotive technologies (e.g., autonomous vehicle technologies) may require significant capital expenditures that may not generate profits for several years, if ever. Automotive companies may be significantly subject to government policies and regulations regarding imports and exports of automotive products. Governmental policies affecting the automotive industry, such as taxes, tariffs, duties, subsidies, and import and export restrictions on automotive products can influence industry profitability. In addition, such companies must comply with environmental laws and regulations, for which there may be severe consequences for non-compliance. While most of the major automotive manufacturers are large companies, certain others may be non-diversified in both product line and customer base and may be more vulnerable to certain events that may negatively impact the automotive industry.
|
| Tuttle Capital TSLA Put Write ETF | Consumer Discretionary Sector Risk [Member] | |
| Prospectus [Line Items] | |
| 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 consumer spending, and may be strongly affected by social trends and marketing campaigns. 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.
|
| Tuttle Capital TSLA Put Write ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. |
| Tuttle Capital TSLA Put Write ETF | Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or any government agency. |
| Tuttle Capital TSLA Put Write ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
|
| Tuttle Capital NVDA Put Write ETF | Put Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Put Options Risk. Puts are subject to volatile swings in price influenced by changes in the value of the underlying instrument. The price of the Puts sold by the Fund will have imperfect correlation to the returns of the Underlying Security. Although the Fund collects premiums on the Puts it writes, the Fund’s risk of loss if the value of the Underlying Security falls below the strike price and the Puts are exercised as of the Roll Date (i.e., the Fund, as the seller of the Puts, owes the buyer of the Puts) will likely outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price (multiplied by 100) of each option it sells.

The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. Additionally, FLEX Options may be illiquid, and in such cases, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices.

When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related record date for the distribution. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.

| Risk [Text Block] | Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

| Tuttle Capital NVDA Put Write ETF | U.S. Treasury Bills Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Bills Risk. U.S. Treasury bills may differ from other debt securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury bills holdings to decline.

| Tuttle Capital NVDA Put Write ETF | ETF Structure Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and is therefore subject to special risks. Such risks include:
|
| Tuttle Capital NVDA Put Write ETF | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Issues Risk. Trading in ETF shares on an exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in the ETF’s shares inadvisable, such as extraordinary market volatility. There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.
|
| Tuttle Capital NVDA Put Write ETF | Market Price Variance Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Price Variance Risk. The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.

| Tuttle Capital NVDA Put Write ETF | Authorized Participants ("APs"), Market Makers, and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. ETFs have a limited number of financial institutions that may act as 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 of an ETF may trade at a material discount to NAV and possibly face delisting: () 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.

| Risk [Text Block] | Industry Concentration Risk. The Fund will be concentrated in the industry to which NVIDIA Corp. is assigned (i.e., hold more than 25% of its total assets in investments that provide inverse exposure to the industry to which NVIDIA 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, NVDA is assigned to the semiconductors and related devices industry.
|
| Tuttle Capital NVDA Put Write ETF | 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 may decline.
|
| Tuttle Capital NVDA Put Write ETF | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk. Interest rate risk is the risk that the value of the Fund’s investments will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term options and debt securities and higher for longer-term options and debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. When interest rates increase, call options generally benefit while put option prices are impacted negatively.
|
| Tuttle Capital NVDA Put Write ETF | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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.

|
| Tuttle Capital NVDA Put Write ETF | NVIDIA Corp. Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | NVIDIA Corp. 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. As of the date of this prospectus, in addition to the risks associated generally with operating companies and companies in the semiconductor industry, NVIDIA faces risks specifically related to its operations that could cause the company to lose market share and revenue, adversely impacting its financial results and its stock price. These risks include, among others, failure to meet the evolving needs of its industry and market; competition in its current and target markets; failure to estimate customer demand; dependency on third-party suppliers; defects in its products; adverse economic, political, business and other changes in international regions in which the company operates; product, system security, and data breaches and cyber-attacks; adverse changes in laws, rules and regulations; increased scrutiny from shareholders, regulators and others regarding the company’s environmental, social and governance responsibilities; issues relating to the responsible use of the company’s technologies, including artificial intelligence; issues relating to the protection of the company’s intellectual property rights; the risks of litigation, investigation and regulatory proceedings; and the company’s level of indebtedness.
|
| Tuttle Capital NVDA Put Write ETF | Cryptocurrency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cryptocurrency Risk. The Fund may have exposure to cryptocurrencies such as bitcoin as a result of NVIDIA’s reliance on sales of its products to cryptocurrency miners. Miners generate revenue from both newly created bitcoin (known as the “block reward”) and from fees taken upon verification of transactions. If the aggregate revenue from transaction fees and the block reward is below a miner’s cost, the miner may cease operations. An acute cessation of mining operations would reduce the collective processing power on the blockchain. A large-scale cessation, either due to policy intervention or other reasons, may also cause higher volatility in bitcoin price, lower process power of the bitcoin network, and higher transaction costs.
A cryptocurrency operates without central authority or banks and is not backed by any government. Cryptocurrencies are often referred to as a “virtual currency” or “digital currency,” and operate as a decentralized, peer-to-peer financial exchange and value storage that is used like money. A cryptocurrency is also not a legal tender. Although Bitcoin and similar crypto assets have been called “cryptocurrencies”, they are not widely accepted as a means of payment. Federal, state or foreign governments may restrict the use and exchange of a cryptocurrency, and regulation in the U.S. is still developing. Cryptocurrency platforms may stop operating or permanently shut down due to fraud, technical glitches, hackers or malware. The Fund’s indirect exposure to cryptocurrencies such as bitcoin may be affected by the high volatility associated with such cryptocurrency exposure. Future regulatory actions or policies may limit the ability to sell, exchange or use cryptocurrencies, thereby impairing their prices. Cryptocurrency trading platforms on which cryptocurrencies trade may be subject to enforcement actions by regulatory authorities.

| Tuttle Capital NVDA Put Write ETF | Semiconductor Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Semiconductor Company Risk. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.
|
| Tuttle Capital NVDA Put Write ETF | Technology Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Technology Sector Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the Fund’s investments. The value of stocks of 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 foreign competitors with lower production costs. 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 technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

| Tuttle Capital NVDA Put Write ETF | Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or any government agency. |
| Tuttle Capital NVDA Put Write ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
|
| Tuttle Capital MSTR Put Write ETF | Put Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Put Options Risk. Puts are subject to volatile swings in price influenced by changes in the value of the underlying instrument. The price of the Puts sold by the Fund will have imperfect correlation to the returns of the Underlying Security. Although the Fund collects premiums on the Puts it writes, the Fund’s risk of loss if the value of the Underlying Security falls below the strike price and the Puts are exercised as of the Roll Date (i.e., the Fund, as the seller of the Puts, owes the buyer of the Puts) will likely outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price (multiplied by 100) of each option it sells.
|
| Tuttle Capital MSTR Put Write ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as an index, interest rate or inflation rate. Generally, derivatives are sophisticated investments that may pose risks that are different from or greater than those posed by investing directly in the underlying reference asset. For example, the return on a derivative instrument may not correlate with that of its underlying reference asset, and minimal requisite initial investments necessary to purchase derivatives positions may expose the Fund to losses in excess of those amounts. Derivatives also can be volatile and may be less liquid than other investments. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. The Fund expects to use put options to implement its principal investment strategies. Other risks specific to put options, as well as other risks of derivatives, generally, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk, are described in greater detail elsewhere in the Fund’s Prospectus.
|
| Tuttle Capital MSTR Put Write ETF | Limited Upside Return Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Upside Return Risk. The Fund’s put option sales strategy subjects the Fund to an upside limitation on returns to the premiums received from the Put owner. The Fund will only participate in upside price swings of the Underlying Security to the extent that the Put sold by the Fund will not be exercised and the Fund will keep all of the premium paid by the Put owner without having to purchase the Underlying Security from the Put owner. In the event an investor purchases Fund shares between Roll Dates, and the value of the Underlying Security falls to a level near or below the strike price, there may be little or no ability for that investor to experience a gain on an investment in Fund shares until the next Roll Date.
|
| Tuttle Capital MSTR Put Write ETF | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may write FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. Additionally, FLEX Options may be illiquid, and in such cases, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices.
|
| Tuttle Capital MSTR Put Write ETF | Rolling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rolling Risk. The Fund’s investment strategy is subject to risks related to rolling. To the extent the Fund’s portfolio managers are unable to roll the Puts as described in the Fund’s principal investment strategy, the Fund may be unable to achieve its investment objective. In addition, because of the frequency with which the Fund expects to roll option contracts, this risk may be greater than the impact would otherwise be if the Fund experienced less portfolio turnover. The price of options contracts further from expiration may be higher, which can impact the Fund’s returns.
|
| Tuttle Capital MSTR Put Write ETF | Assignment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Assignment Risk. The Puts written by the Fund may be assigned to the Fund at any point prior to the expiration date. Early assignment is more likely when the put option is significantly in the money. Should early assignment occur for a put options position, it would result in the Fund acquiring the assigned shares. Consequently, the value of the Fund’s investment may be temporarily exposed to the full market movement of the Underlying Security and the risks attendant to the Underlying Security (explained more fully below), until these shares are sold off and new options positions are established. The Adviser will generally seek to liquidate the assigned shares and re-establish the options position as soon as possible to ensure gains or losses stemming from early assignments are minimized.
|
| Tuttle Capital MSTR Put Write ETF | Implied Volatility Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Implied Volatility Risk. Upon selling a Put, the Fund gains the amount of premium it receives; however, the Fund also incurs a liability that represents the value of the Put it has sold until the Put is exercised or expires. The value of the Puts in which the Fund invests is partly based on the volatility used by market participants to price such options (i.e., implied volatility). Consequently, increases in the implied volatility of the Puts will cause the value of such options to increase (even if the prices of stocks in the Underlying Security do not change), which will result in a corresponding increase in the liabilities of the Fund under the Puts and thus decrease the Fund’s NAV. The Fund is therefore exposed to implied volatility risk before the Puts expire or are struck at-the-money. The implied volatility of the Puts sold by the Fund may increase due to general market and economic conditions, perceptions regarding the industries of companies included in the Underlying Security, or factors relating to certain of those companies.
|
| Tuttle Capital MSTR Put Write ETF | Transaction Cost Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Transaction Cost Risk. The Fund will pay transaction costs, such as commissions or mark-ups in the bid/offer spread on an option position, when it writes options. Because the Fund “turns over” its option positions every week (or more frequently), it will incur high transaction costs. While the turnover of the option positions sold by the Fund is not deemed “portfolio turnover” for accounting purposes, the economic impact to the Fund is similar to what could occur if the Fund experienced high portfolio turnover (e.g., in excess of 100% per year). The Fund’s high levels of transaction costs may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example thereunder, may affect the Fund’s performance.
|
| Tuttle Capital MSTR Put Write ETF | Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. As with all investments, an investment in the Fund is subject to loss, including the possible loss of the entire principal amount of an investment, over short or long periods of time.
|
| Tuttle Capital MSTR Put Write ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
|
| Tuttle Capital MSTR Put Write ETF | Cash Redemption Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes 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 Fund redeemed shares in kind.
|
| Tuttle Capital MSTR Put Write ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Equity securities may be more volatile than other asset classes, and their market prices may change quickly and without warning. The value of an equity security may decrease as a result of the issuer or due to general industry or market conditions unrelated to the issuer. If the value of the Underlying Security decreases or fluctuates, causing the value of the Underlying Security on the Roll Date to fall below the strike price of the Puts sold by the Fund, the NAV of the Fund will decrease or fluctuate, respectively, as the Puts increase in value to their owners. The Fund may also lose value to the extent that it takes delivery of the Underlying Security and has to sell such Underlying Security at a lower price.
|
| Tuttle Capital MSTR Put Write ETF | Active Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement its investment strategies for the Fund. The success of the Fund’s investment program depends largely on the investment techniques applied by the Adviser. It is possible the investment techniques employed on behalf of the Fund will not produce the desired results.
|
| Tuttle Capital MSTR Put Write ETF | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund may, when the Adviser in its discretion deems appropriate, purchase put and/or call options to hedge against the risk of drastic movements in the price of the Underlying Security and may engage in other various investments or transactions that are designed to hedge a position in the Fund’s portfolio. There is no assurance that these hedging techniques will be effective and such techniques involve costs that may reduce gains or result in losses, which may adversely affect the value of Fund shares.
|
| Tuttle Capital MSTR Put Write ETF | Purchase and Sale Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Purchase and Sale Timing Risk. The Fund has multiple Roll Dates each month and, as a result, no matter when an investor purchases Fund shares, even on a Roll Date, the value of the investor’s investment in the Fund may not be protected against a decline in the value of the Underlying Security and may not benefit from a gain in the value of the Underlying Security. The value of the options written by the Fund is dependent on various factors, including, but not limited to, the value and implied volatility of the Underlying Security. Each of these factors may vary significantly during the period between Roll Dates and affect the Fund’s ability to achieve its investment objective between Roll Dates.
|
| Tuttle Capital MSTR Put Write ETF | Distribution and Return of Capital Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Distribution and Return of Capital Risk. The Fund seeks to provide current monthly income. There is no guarantee that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related record date for the distribution. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.

U.S. Treasury bills may differ from other debt securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those other securities.

There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.

The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.

Interest rate risk is generally lower for shorter term options and debt securities and higher for longer-term options and debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

| Tuttle Capital MSTR Put Write ETF | MicroStrategy Inc. Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | MicroStrategy Inc. 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. As of the date of this prospectus, in addition to the risks associated generally with operating companies and companies in the semiconductor industry, MSTR faces risks specifically related to its operations that could cause the company to lose market share and revenue, adversely impacting its financial results and its stock price. These risks include, among others, failure to meet the evolving needs of its industry and market; competition in its current and target markets; failure to estimate customer demand; dependency on third-party suppliers; defects in its products; adverse economic, political, business and other changes in international regions in which the company operates; product, system security, and data breaches and cyber-attacks; adverse changes in laws, rules and regulations; increased scrutiny from shareholders, regulators and others regarding the company’s environmental, social and governance responsibilities; issues relating to the responsible use of the company’s technologies, including artificial intelligence; issues relating to the protection of the company’s intellectual property rights; the risks of litigation, investigation and regulatory proceedings; and the company’s level of indebtedness. In addition, as a result of the company’s bitcoin acquisition strategy and its treasury reserve policy, the majority of the company’s assets are concentrated in its bitcoin holdings. The concentration of the company’s assets in bitcoin limits its ability to mitigate risk that could otherwise be achieved by purchasing a more diversified portfolio of treasury assets. Accordingly, a significant decline in the market value of bitcoin could have a material adverse effect on the company’s financial condition. Any material adverse effect on the company’s financial condition caused by a significant decline in the market value of its bitcoin holdings may create liquidity and credit risks for its business operations, as the company would have limited means to obtain cash beyond the revenues generated by its enterprise analytics software business. To the extent that the cash generated by the company’s enterprise analytics software business is insufficient to satisfy its debt service obligations, and to the extent that the liquidation of its bitcoin holdings would be insufficient to satisfy the company’s debt service obligations, the company may be unable to make scheduled payments on its current or future indebtedness, which could cause the company to default on its debt obligations. See “Bitcoin Risk.”
Cryptocurrency Risk. The Fund may have exposure to cryptocurrencies such as bitcoin as a result of MicroStrategy’s reliance on sales of its products to cryptocurrency miners. Miners generate revenue from both newly created bitcoin (known as the “block reward”) and from fees taken upon verification of transactions. If the aggregate revenue from transaction fees and the block reward is below a miner’s cost, the miner may cease operations. An acute cessation of mining operations would reduce the collective processing power on the blockchain. A large-scale cessation, either due to policy intervention or other reasons, may also cause higher volatility in bitcoin price, lower process power of the bitcoin network, and higher transaction costs.
A cryptocurrency operates without central authority or banks and is not backed by any government. Cryptocurrencies are often referred to as a “virtual currency” or “digital currency,” and operate as a decentralized, peer-to-peer financial exchange and value storage that is used like money. A cryptocurrency is also not a legal tender. Although Bitcoin and similar crypto assets have been called “cryptocurrencies”, they are not widely accepted as a means of payment. Federal, state or foreign governments may restrict the use and exchange of a cryptocurrency, and regulation in the U.S. is still developing. Cryptocurrency platforms may stop operating or permanently shut down due to fraud, technical glitches, hackers or malware. The Fund’s indirect exposure to cryptocurrencies such as bitcoin may be affected by the high volatility associated with such cryptocurrency exposure. Future regulatory actions or policies may limit the ability to sell, exchange or use cryptocurrencies, thereby impairing their prices. Cryptocurrency trading platforms on which cryptocurrencies trade may be subject to enforcement actions by regulatory authorities.

| Tuttle Capital MSTR Put Write ETF | Information Technology Industry Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Information Technology Industry 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.

| Tuttle Capital MSTR Put Write ETF | Bitcoin Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Bitcoin Risk. While the Fund will not directly invest in digital assets, it will be subject to the risks associated with bitcoin by virtue of its investments in options contracts that reference MSTR. MSTR invests a large percentage of its assets in bitcoin (approximately 82% as of September 30, 2024). Investing in bitcoin exposes investors (such as MSTR and, in turn, MSTR shareholders) to significant risks that are not typically present in other investments. These risks include the uncertainty surrounding new technology, limited evaluation due to bitcoin’s short trading history, and the potential decline in adoption and value over the long term. The extreme volatility of bitcoin’s price is also a risk factor. Regulatory uncertainties, such as potential government interventions and conflicting regulations across jurisdictions, can impact the demand for bitcoin and restrict its usage. Additionally, risks associated with the sale of newly mined bitcoin, Bitcoin platforms, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to bitcoin-linked investments.
Bitcoin blockchain protocol may contain flaws that can be exploited by attackers and which may adversely affect the value of bitcoin. Flaws in the source code for digital assets have been exploited including flaws that disabled some functionality for users, exposed users’ personal information and/or resulted in the theft of users’ digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the Bitcoin network. Exposure of bitcoin to instability in other speculative parts of the blockchain and crypto industry, such as through an event that is not necessarily related to the security or utility of the Bitcoin blockchain can nonetheless precipitate a significant decline in the price of bitcoin. Proposed changes to the Bitcoin blockchain protocol may not be adopted by a sufficient number of users and miners, which may result in competing blockchains with different native crypto assets and sets of participants (known as a “fork”).
Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoins by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions; process wire transfers to or from digital asset platforms, bitcoin-related companies or service providers; or maintain accounts for persons or entities transacting in bitcoin. Processing of bitcoin transactions may be slow and transaction fees may be subject to significant variability. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future.
Further developments in blockchain for its intended purpose may depend on Layer 2 scaling solutions (“Layer 2 Solutions”). Layer 2 Solutions are protocols that allow developers to build applications with faster transaction ability and cheaper costs than if they were to build on the layer 1 chain, which refers to decentralized applications built on the Bitcoin main chain. There are various types of scaling solutions for bitcoin that will assist in the implementation of Layer 2 Solutions. For bitcoin to be suitable for global enterprise and mass adoption, there first needs to be improvements that facilitate scaling and transaction speed to keep up with user demand, and accommodating the various types of users and transaction requests. The Bitcoin Lightning Network is a Layer 2 Solution that uses channels to create peer-to-peer payment routs between two parties. These exist separately from bitcoin’s network and their primary purpose is to allow for faster transactions. Since these Layer 2 Solutions are recorded off of the Bitcoin network this results in slower verification times for these transactions, and users may be subject to manipulation of the transaction data by unauthorized parties. This may result in users and retailers being less likely to accept bitcoin as a form of payment, and cause a decrease in the value of bitcoin and the performance of the Fund. Competition from the emergence or growth of alternative digital assets and smart contracts platforms, such as those focused on zero-knowledge cryptography, Solana, Avalanche, Polkadot, or Cardano, could have a negative impact on the demand for, and price of, bitcoin.

| Tuttle Capital MSTR Put Write ETF | Computer Software Industry Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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.

| Tuttle Capital MSTR Put Write ETF | Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or any government agency. |
| Tuttle Capital MSTR Put Write ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
|
| Tuttle Capital COIN Put Write ETF | Put Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Put Options Risk. Puts are subject to volatile swings in price influenced by changes in the value of the underlying instrument. The price of the Puts sold by the Fund will have imperfect correlation to the returns of the Underlying Security. Although the Fund collects premiums on the Puts it writes, the Fund’s risk of loss if the value of the Underlying Security falls below the strike price and the Puts are exercised as of the Roll Date (i.e., the Fund, as the seller of the Puts, owes the buyer of the Puts) will likely outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price (multiplied by 100) of each option it sells.
|
| Tuttle Capital COIN Put Write ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as an index, interest rate or inflation rate. Generally, derivatives are sophisticated investments that may pose risks that are different from or greater than those posed by investing directly in the underlying reference asset. For example, the return on a derivative instrument may not correlate with that of its underlying reference asset, and minimal requisite initial investments necessary to purchase derivatives positions may expose the Fund to losses in excess of those amounts. Derivatives also can be volatile and may be less liquid than other investments. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. The Fund expects to use put options to implement its principal investment strategies. Other risks specific to put options, as well as other risks of derivatives, generally, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk, are described in greater detail elsewhere in the Fund’s Prospectus.
|
| Tuttle Capital COIN Put Write ETF | Limited Upside Return Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Upside Return Risk. The Fund’s put option sales strategy subjects the Fund to an upside limitation on returns to the premiums received from the Put owner. The Fund will only participate in upside price swings of the Underlying Security to the extent that the Put sold by the Fund will not be exercised and the Fund will keep all of the premium paid by the Put owner without having to purchase the Underlying Security from the Put owner. In the event an investor purchases Fund shares between Roll Dates, and the value of the Underlying Security falls to a level near or below the strike price, there may be little or no ability for that investor to experience a gain on an investment in Fund shares until the next Roll Date.
|
| Tuttle Capital COIN Put Write ETF | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may write FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. Additionally, FLEX Options may be illiquid, and in such cases, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices.
|
| Tuttle Capital COIN Put Write ETF | Rolling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rolling Risk. The Fund’s investment strategy is subject to risks related to rolling. To the extent the Fund’s portfolio managers are unable to roll the Puts as described in the Fund’s principal investment strategy, the Fund may be unable to achieve its investment objective. In addition, because of the frequency with which the Fund expects to roll option contracts, this risk may be greater than the impact would otherwise be if the Fund experienced less portfolio turnover. The price of options contracts further from expiration may be higher, which can impact the Fund’s returns.
|
| Tuttle Capital COIN Put Write ETF | Assignment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Assignment Risk. The Puts written by the Fund may be assigned to the Fund at any point prior to the expiration date. Early assignment is more likely when the put option is significantly in the money. Should early assignment occur for a put options position, it would result in the Fund acquiring the assigned shares. Consequently, the value of the Fund’s investment may be temporarily exposed to the full market movement of the Underlying Security and the risks attendant to the Underlying Security (explained more fully below), until these shares are sold off and new options positions are established. The Adviser will generally seek to liquidate the assigned shares and re-establish the options position as soon as possible to ensure gains or losses stemming from early assignments are minimized.
|
| Tuttle Capital COIN Put Write ETF | Implied Volatility Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Implied Volatility Risk. Upon selling a Put, the Fund gains the amount of premium it receives; however, the Fund also incurs a liability that represents the value of the Put it has sold until the Put is exercised or expires. The value of the Puts in which the Fund invests is partly based on the volatility used by market participants to price such options (i.e., implied volatility). Consequently, increases in the implied volatility of the Puts will cause the value of such options to increase (even if the prices of stocks in the Underlying Security do not change), which will result in a corresponding increase in the liabilities of the Fund under the Puts and thus decrease the Fund’s NAV. The Fund is therefore exposed to implied volatility risk before the Puts expire or are struck at-the-money. The implied volatility of the Puts sold by the Fund may increase due to general market and economic conditions, perceptions regarding the industries of companies included in the Underlying Security, or factors relating to certain of those companies.
|
| Tuttle Capital COIN Put Write ETF | Transaction Cost Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Transaction Cost Risk. The Fund will pay transaction costs, such as commissions or mark-ups in the bid/offer spread on an option position, when it writes options. Because the Fund “turns over” its option positions every week (or more frequently), it will incur high transaction costs. While the turnover of the option positions sold by the Fund is not deemed “portfolio turnover” for accounting purposes, the economic impact to the Fund is similar to what could occur if the Fund experienced high portfolio turnover (e.g., in excess of 100% per year). The Fund’s high levels of transaction costs may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example thereunder, may affect the Fund’s performance.
|
| Tuttle Capital COIN Put Write ETF | Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. As with all investments, an investment in the Fund is subject to loss, including the possible loss of the entire principal amount of an investment, over short or long periods of time.
|
| Tuttle Capital COIN Put Write ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
|
| Tuttle Capital COIN Put Write ETF | Cash Redemption Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes 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 Fund redeemed shares in kind.
|
| Tuttle Capital COIN Put Write ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Equity securities may be more volatile than other asset classes, and their market prices may change quickly and without warning. The value of an equity security may decrease as a result of the issuer or due to general industry or market conditions unrelated to the issuer. If the value of the Underlying Security decreases or fluctuates, causing the value of the Underlying Security on the Roll Date to fall below the strike price of the Puts sold by the Fund, the NAV of the Fund will decrease or fluctuate, respectively, as the Puts increase in value to their owners. The Fund may also lose value to the extent that it takes delivery of the Underlying Security and has to sell such Underlying Security at a lower price.
|
| Tuttle Capital COIN Put Write ETF | Active Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement its investment strategies for the Fund. The success of the Fund’s investment program depends largely on the investment techniques applied by the Adviser. It is possible the investment techniques employed on behalf of the Fund will not produce the desired results.
|
| Tuttle Capital COIN Put Write ETF | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund may, when the Adviser in its discretion deems appropriate, purchase put and/or call options to hedge against the risk of drastic movements in the price of the Underlying Security and may engage in other various investments or transactions that are designed to hedge a position in the Fund’s portfolio. There is no assurance that these hedging techniques will be effective and such techniques involve costs that may reduce gains or result in losses, which may adversely affect the value of Fund shares.
|
| Tuttle Capital COIN Put Write ETF | Purchase and Sale Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Purchase and Sale Timing Risk. The Fund has multiple Roll Dates each month and, as a result, no matter when an investor purchases Fund shares, even on a Roll Date, the value of the investor’s investment in the Fund may not be protected against a decline in the value of the Underlying Security and may not benefit from a gain in the value of the Underlying Security. The value of the options written by the Fund is dependent on various factors, including, but not limited to, the value and implied volatility of the Underlying Security. Each of these factors may vary significantly during the period between Roll Dates and affect the Fund’s ability to achieve its investment objective between Roll Dates.
|
| Tuttle Capital COIN Put Write ETF | Distribution and Return of Capital Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Distribution and Return of Capital Risk. The Fund seeks to provide current monthly income. There is no guarantee that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related record date for the distribution. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.
|
| Tuttle Capital COIN Put Write ETF | Money Market Instruments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.
|
| Tuttle Capital COIN Put Write ETF | U.S. Treasury Bills Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Bills Risk. U.S. Treasury bills may differ from other debt securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury bills holdings to decline.

| Tuttle Capital COIN Put Write ETF | ETF Structure Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and is therefore subject to special risks. Such risks include:
|
| Tuttle Capital COIN Put Write ETF | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Issues Risk. Trading in ETF shares on an exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in the ETF’s shares inadvisable, such as extraordinary market volatility. There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.
|
| Tuttle Capital COIN Put Write ETF | Market Price Variance Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Price Variance Risk. The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.
|
| Tuttle Capital COIN Put Write ETF | Authorized Participants ("APs"), Market Makers, and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. ETFs have a limited number of financial institutions that may act as 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 of an ETF may trade at a material discount to NAV and possibly face delisting: () 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.

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 assigned to the financial sector and the capital markets industry.

| Tuttle Capital COIN Put Write ETF | 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 may decline.
|
| Tuttle Capital COIN Put Write ETF | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk. Interest rate risk is the risk that the value of the Fund’s investments will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term options and debt securities and higher for longer-term options and debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. When interest rates increase, call options generally benefit while put option prices are impacted negatively.

| Tuttle Capital COIN Put Write ETF | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. As of the date of this prospectus, the Fund has no operating history and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

The 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 generally with operating companies and companies in the semiconductor industry, COIN faces risks specifically related to its operations that could cause the company to lose market share and revenue, adversely impacting its financial results and its stock price. These risks include, among others, failure to meet the evolving needs of its industry and market; competition in its current and target markets; failure to estimate customer demand; dependency on third-party suppliers; defects in its products; adverse economic, political, business and other changes in international regions in which the company operates; product, system security, and data breaches and cyber-attacks; adverse changes in laws, rules and regulations; increased scrutiny from shareholders, regulators and others regarding the company’s environmental, social and governance responsibilities; issues relating to the responsible use of the company’s technologies, including artificial intelligence; issues relating to the protection of the company’s intellectual property rights; the risks of litigation, investigation and regulatory proceedings; and the company’s level of indebtedness.

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.

| Tuttle Capital COIN Put Write ETF | Financials Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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 financials 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.

| Tuttle Capital COIN Put Write ETF | Capital Markets Industry Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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.

| Tuttle Capital COIN Put Write ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with all funds, a shareholder is subject to the risk that his or her investment could lose money. |
| Tuttle Capital COIN Put Write ETF | Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “ FDIC”) or any government agency. |
| Tuttle Capital COIN Put Write ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
|
| Tuttle Capital QQQ Put Write ETF | Put Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Put Options Risk. Puts are subject to volatile swings in price influenced by changes in the value of the underlying instrument. The price of the Puts sold by the Fund will have imperfect correlation to the returns of the Underlying Security. Although the Fund collects premiums on the Puts it writes, the Fund’s risk of loss if the value of the Underlying Security falls below the strike price and the Puts are exercised as of the Roll Date (i.e., the Fund, as the seller of the Puts, owes the buyer of the Puts) will likely outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price (multiplied by 100) of each option it sells.
|
| Tuttle Capital QQQ Put Write ETF | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as an index, interest rate or inflation rate. Generally, derivatives are sophisticated investments that may pose risks that are different from or greater than those posed by investing directly in the underlying reference asset. For example, the return on a derivative instrument may not correlate with that of its underlying reference asset, and minimal requisite initial investments necessary to purchase derivatives positions may expose the Fund to losses in excess of those amounts. Derivatives also can be volatile and may be less liquid than other investments. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. The Fund expects to use put options to implement its principal investment strategies. Other risks specific to put options, as well as other risks of derivatives, generally, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk, are described in greater detail elsewhere in the Fund’s Prospectus.
|
| Tuttle Capital QQQ Put Write ETF | Limited Upside Return Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Upside Return Risk. The Fund’s put option sales strategy subjects the Fund to an upside limitation on returns to the premiums received from the Put owner. The Fund will only participate in upside price swings of the Underlying Security to the extent that the Put sold by the Fund will not be exercised and the Fund will keep all of the premium paid by the Put owner without having to purchase the Underlying Security from the Put owner. In the event an investor purchases Fund shares between Roll Dates, and the value of the Underlying Security falls to a level near or below the strike price, there may be little or no ability for that investor to experience a gain on an investment in Fund shares until the next Roll Date.
|
| Tuttle Capital QQQ Put Write ETF | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may write FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. Additionally, FLEX Options may be illiquid, and in such cases, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices.
|
| Tuttle Capital QQQ Put Write ETF | Rolling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rolling Risk. The Fund’s investment strategy is subject to risks related to rolling. To the extent the Fund’s portfolio managers are unable to roll the Puts as described in the Fund’s principal investment strategy, the Fund may be unable to achieve its investment objective. In addition, because of the frequency with which the Fund expects to roll option contracts, this risk may be greater than the impact would otherwise be if the Fund experienced less portfolio turnover. The price of options contracts further from expiration may be higher, which can impact the Fund’s returns.
|
| Tuttle Capital QQQ Put Write ETF | Assignment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Assignment Risk. The Puts written by the Fund may be assigned to the Fund at any point prior to the expiration date. Early assignment is more likely when the put option is significantly in the money. Should early assignment occur for a put options position, it would result in the Fund acquiring the assigned shares. Consequently, the value of the Fund’s investment may be temporarily exposed to the full market movement of the Underlying Security and the risks attendant to the Underlying Security (explained more fully below), until these shares are sold off and new options positions are established. The Adviser will generally seek to liquidate the assigned shares and re-establish the options position as soon as possible to ensure gains or losses stemming from early assignments are minimized.
|
| Tuttle Capital QQQ Put Write ETF | Implied Volatility Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Implied Volatility Risk. Upon selling a Put, the Fund gains the amount of premium it receives; however, the Fund also incurs a liability that represents the value of the Put it has sold until the Put is exercised or expires. The value of the Puts in which the Fund invests is partly based on the volatility used by market participants to price such options (i.e., implied volatility). Consequently, increases in the implied volatility of the Puts will cause the value of such options to increase (even if the prices of stocks in the Underlying Security do not change), which will result in a corresponding increase in the liabilities of the Fund under the Puts and thus decrease the Fund’s NAV. The Fund is therefore exposed to implied volatility risk before the Puts expire or are struck at-the-money. The implied volatility of the Puts sold by the Fund may increase due to general market and economic conditions, perceptions regarding the industries of companies included in the Underlying Security, or factors relating to certain of those companies.
|
| Tuttle Capital QQQ Put Write ETF | Transaction Cost Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Transaction Cost Risk. The Fund will pay transaction costs, such as commissions or mark-ups in the bid/offer spread on an option position, when it writes options. Because the Fund “turns over” its option positions every week (or more frequently), it will incur high transaction costs. While the turnover of the option positions sold by the Fund is not deemed “portfolio turnover” for accounting purposes, the economic impact to the Fund is similar to what could occur if the Fund experienced high portfolio turnover (e.g., in excess of 100% per year). The Fund’s high levels of transaction costs may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example thereunder, may affect the Fund’s performance.
|
| Tuttle Capital QQQ Put Write ETF | Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. As with all investments, an investment in the Fund is subject to loss, including the possible loss of the entire principal amount of an investment, over short or long periods of time.
|
| Tuttle Capital QQQ Put Write ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
|
| Tuttle Capital QQQ Put Write ETF | Cash Redemption Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes 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 Fund redeemed shares in kind.
|
| Tuttle Capital QQQ Put Write ETF | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Equity securities may be more volatile than other asset classes, and their market prices may change quickly and without warning. The value of an equity security may decrease as a result of the issuer or due to general industry or market conditions unrelated to the issuer. If the value of the Underlying Security decreases or fluctuates, causing the value of the Underlying Security on the Roll Date to fall below the strike price of the Puts sold by the Fund, the NAV of the Fund will decrease or fluctuate, respectively, as the Puts increase in value to their owners. The Fund may also lose value to the extent that it takes delivery of the Underlying Security and has to sell such Underlying Security at a lower price.
|
| Tuttle Capital QQQ Put Write ETF | Active Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement its investment strategies for the Fund. The success of the Fund’s investment program depends largely on the investment techniques applied by the Adviser. It is possible the investment techniques employed on behalf of the Fund will not produce the desired results.
|
| Tuttle Capital QQQ Put Write ETF | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund may, when the Adviser in its discretion deems appropriate, purchase put and/or call options to hedge against the risk of drastic movements in the price of the Underlying Security and may engage in other various investments or transactions that are designed to hedge a position in the Fund’s portfolio. There is no assurance that these hedging techniques will be effective and such techniques involve costs that may reduce gains or result in losses, which may adversely affect the value of Fund shares.
|
| Tuttle Capital QQQ Put Write ETF | Purchase and Sale Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Purchase and Sale Timing Risk. The Fund has multiple Roll Dates each month and, as a result, no matter when an investor purchases Fund shares, even on a Roll Date, the value of the investor’s investment in the Fund may not be protected against a decline in the value of the Underlying Security and may not benefit from a gain in the value of the Underlying Security. The value of the options written by the Fund is dependent on various factors, including, but not limited to, the value and implied volatility of the Underlying Security. Each of these factors may vary significantly during the period between Roll Dates and affect the Fund’s ability to achieve its investment objective between Roll Dates.
|
| Tuttle Capital QQQ Put Write ETF | Distribution and Return of Capital Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Distribution and Return of Capital Risk. The Fund seeks to provide current monthly income. There is no guarantee that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related record date for the distribution. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.
|
| Tuttle Capital QQQ Put Write ETF | Money Market Instruments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.
|
| Tuttle Capital QQQ Put Write ETF | U.S. Treasury Bills Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Bills Risk. U.S. Treasury bills may differ from other debt securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury bills holdings to decline.
|
| Tuttle Capital QQQ Put Write ETF | ETF Structure Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and is therefore subject to special risks. Such risks include:
|
| Tuttle Capital QQQ Put Write ETF | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading Issues Risk. Trading in ETF shares on an exchange may be halted due to market conditions or for reasons that, in the view of the exchange, make trading in the ETF’s shares inadvisable, such as extraordinary market volatility. There can be no assurance that an ETF’s shares will continue to meet the listing requirements of its exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of an ETF. In stressed market conditions, the liquidity of shares of an ETF may begin to mirror the liquidity of the ETF’s underlying portfolio holdings, which can be significantly less liquid than shares of the ETF. This adverse effect on liquidity for the ETF’s shares in turn could lead to differences between the market price of the ETF’s shares and the underlying value of those shares.
|
| Tuttle Capital QQQ Put Write ETF | Market Price Variance Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Price Variance Risk. The market prices of shares of an ETF will fluctuate in response to changes in the ETF’s NAV, and supply and demand for ETF shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that ETF shares may trade at a discount to NAV. The market price of an ETF’s shares may deviate from the value of the ETF’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the ETF bought or sold.
|
| Tuttle Capital QQQ Put Write ETF | Authorized Participants ("APs"), Market Makers, and Liquidity Providers Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. ETFs have a limited number of financial institutions that may act as 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 of an ETF may trade at a material discount to NAV and possibly face delisting: () 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.

| Tuttle Capital QQQ Put Write ETF | 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 may decline.
|
| Tuttle Capital QQQ Put Write ETF | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk. Interest rate risk is the risk that the value of the Fund’s investments will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term options and debt securities and higher for longer-term options and debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. When interest rates increase, call options generally benefit while put option prices are impacted negatively.
|
| Tuttle Capital QQQ Put Write ETF | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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.

| Prospectus [Line Items] | |
| Risk [Text Block] | Technology Sector Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the Fund’s investments. The value of stocks of 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 foreign competitors with lower production costs. 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 technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

| Tuttle Capital QQQ Put Write ETF | INVESCO QQQ Trust, Series 1 Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | INVESCO QQQ Trust, Series 1 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. QQQ is subject to the risk of an investment in a portfolio of equity securities in economic sectors in which the Index may be highly concentrated (e.g., technology) as well as to the risks specific to the performance of a few individual component Securities which currently represent a highly concentrated weighting in the Index. These include the risks that the level of stock prices in these sectors or the stock prices of these specific companies may decline, thereby adversely affecting the value of QQQ. In addition, because it is the policy of the Trust to invest in the securities that comprise the Index, if the Index is concentrated in an industry or industry group, the portfolio of Securities also will be concentrated in that industry or industry group.

| Tuttle Capital QQQ Put Write ETF | American Depositary Receipts ("ADRs"?) Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | American Depositary Receipts (“ADRs”) Risk: QQQ is subject to risks associated with investments in ADRs included in the Index. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. ADRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
