Investment Risks |
Jul. 31, 2026 |
|---|---|
| Formidable ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.
|
| Formidable ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market value of securities owned by the Fund may decline, at times sharply and unpredictably.
|
| Formidable ETF | Active Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Adviser’s investment decisions about individual securities impact the Fund’s ability to achieve its investment objective. The Adviser’s judgments about the attractiveness and potential appreciation of particular investments in which the Fund invests may prove to be incorrect and there is no guarantee that the Adviser’s investment strategy will produce the desired results.
|
| Formidable ETF | Risk Of Other Equity Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Other Equity Securities. Other equity securities in which the Fund may invest include preferred securities, rights and warrants. •Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. •Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

| Risk [Text Block] | Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. |
| Formidable ETF | Risk Of Other Equity Securities, Rights And Warrants Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer. |
| Formidable ETF | ETF Structure Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to special risks, including: •Trading Issues Risk. Although it is expected that shares of the Fund will remain listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”), trading in Fund shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable, such as extraordinary market volatility. There can be no assurance that Fund shares will continue to meet the listing requirements of the Exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of the Fund. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund. This adverse effect on liquidity for the Fund’s shares in turn could lead to differences between the market price of the Fund’s shares and the underlying value of those Shares. •Market Price Variance Risk. The market prices of shares of the Fund will fluctuate in response to changes in the Fund’s net asset value (“NAV”) and supply and demand for Fund 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 Fund shares may trade at a discount to NAV. The market price of Shares may deviate from the value of the Fund’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 Fund bought or sold. •Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. The Fund has 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 the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. The Fund has 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 the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Formidable ETF | ETF Structure Risk, Costs Of Buying Or Selling Shares Of The Fund Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. |
| Formidable ETF | Investment Company Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company Risk. An investment in other investment companies (including other exchange-traded products) is subject to the risks associated with those investment companies, which include, but are not limited to, the risk that such fund’s investment strategy may not produce the intended results; the risk that securities in such fund may underperform in comparison to the general securities markets or other asset classes; and the risk that the fund will be concentrated in a particular issuer, market, industry or sector, and therefore will be especially susceptible to loss due to adverse occurrences affecting that issuer, market, industry or sector. Moreover, the Fund will incur duplicative expenses from such investments, bearing its share of that fund’s expenses while also paying its own advisory fees and trading costs.
|
| Formidable ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The Fund may use derivative instruments such as put and call options on stocks and certain volatility-linked exchange-traded products. There is no guarantee that the use of these instruments by the Fund will work. The value of derivatives may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Other risks of investments in derivatives include imperfect correlation between the value of these instruments and the underlying assets; risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that offset gains in portfolio positions; and risks that the derivative transactions may not be liquid. The Fund’s use of derivatives may magnify losses for the Fund. If the Fund is not successful in employing such instruments in managing its portfolio, its performance will be worse than if it did not invest in such instruments. Successful use by the Fund of options will be subject to its ability to correctly predict movements in the direction of the securities generally or of a particular market segment. In addition, the Fund will pay commissions and other costs in connection with such investments, which may indirectly increase the Fund’s expenses and reduce the return. In utilizing certain derivatives, the Fund’s losses are potentially unlimited. Derivative instruments may also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Fund. The Fund has adopted policies and procedures pursuant to Rule 18f-4 under the Investment Company Act of 1940 relating to the use of derivatives.
|
| Formidable ETF | Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of their underlying securities. Writing call options may reduce the Fund’s ability to profit from increases in the value of the Fund’s portfolio securities. When writing call options on a portfolio security, the Fund receives a premium; however, the premium may not be enough to offset a loss incurred by the Fund if the price of the portfolio security is above the strike price by an amount equal to or greater than the premium. The Fund’s option strategy is designed to provide the Fund with income by taking in options premiums, but it is not designed to mitigate losses to the Fund in the event of a market decline.
|
| Formidable ETF | FLEX Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may invest in 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.
|
| Formidable ETF | Large Capitalization Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Securities Risk. Investments in large capitalization securities as a group could fall out of favor with the market, causing the Fund to underperform investments that focus on small capitalization securities. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
|
| Formidable ETF | Mid And Small Capitalization Stock Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid and Small Capitalization Stock Risk. The value of mid and small capitalization company stocks or ETFs that invest in stocks of mid and small capitalization companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.
|
| Formidable ETF | Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. To the extent the Fund invests in foreign securities, it may be subject to additional risks not typically associated with investments in domestic securities. These risks may include, among others, currency risk, country risks (political, diplomatic, regional conflicts, terrorism, war, social and economic instability, currency devaluations and policies that have the effect of limiting or restricting foreign investment or the movement of assets), different trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility.
|
| Formidable ETF | Leverage Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk. The Fund does not seek leveraged returns but as a result of the Fund’s use of certain derivatives it may create investment leverage. This means that the derivative position may provide the Fund with investment exposure greater than the value of the Fund’s investment in the derivative. As a result, these derivatives may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund.
|
| Formidable ETF | Issuer Non-Diversification Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer Non-Diversification Risk. The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than diversified funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.
|
| Formidable ETF | Investment Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Strategy Risk. The Fund’s investments in securities that the Adviser believes will perform well in a certain macroeconomic environment may not perform as expected. In addition, the Fund’s investment approach may be out of favor at times, causing it to underperform other portfolios that have a similar investment objective.
|
| Formidable ETF | Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, as with any investment, you may lose some or all of your investment by investing in the Fund. |
| Formidable ETF | REITs Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs. Investing in real estate investment trusts (“REITs”) involves unique risks. When the Fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the Fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. U.S. REITs are subject to a number of highly technical tax-related rules and requirements; and a U.S. REIT’s failure to qualify for the favorable U.S. federal income tax treatment generally available to U.S. REITs could result in corporate-level taxation, significantly reducing the return on an investment to the Fund.
|
| Formidable ETF | ETN Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETN Risk. ETNs are senior, unsecured, unsubordinated debt securities of an issuer that are designed to provide returns that are linked to a particular benchmark. ETNs do not provide principal protection and may not make periodic coupon payments. ETNs have a maturity date and generally are backed only by the creditworthiness of the issuer. As a result, ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due.
|
| Formidable ETF | Depositary Receipts Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts. Depositary receipts are generally subject to the same risks that the foreign securities that they evidence or into which they may be converted are, and they may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.
|
| Formidable ETF | Risk Of Highly Volatile Markets Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Highly Volatile Markets. The prices of the derivative instruments in which the Fund may invest, including options and volatility-linked exchange-traded products, can be highly volatile. Price movements of the derivative instruments in which the Fund is invested are influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments, and national and international political and economic events and policies. The Fund is also subject to the risk of failure of any of the exchanges on which its derivative instrument positions trade or failure of their clearinghouses.
|
| Formidable ETF | Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. The Fund is subject to liquidity risk primarily due to its investments in derivatives. Investments in illiquid assets involve the risk that the Fund may be unable to sell such assets or sell them at a reasonable price. Derivatives, especially when traded in large amounts, may not always be liquid. In such cases, in volatile markets the Fund may not be able to close out a position without incurring a loss. Daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivatives may prevent profitable liquidation of positions, subjecting the Fund to potentially greater losses.
|
| Formidable 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. |
| Formidable ETF | Risk Not Insured Depository Institution [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 FDIC or any government agency. |
| Formidable Dividend and Income ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.
|
| Formidable Dividend and Income ETF | Market Risk Member | |

| Risk [Text Block] | Market Risk. The market value of securities owned by the Fund may decline, at times sharply and unpredictably.

REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the Fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. U.S. REITs are subject to a number of highly technical tax-related rules and requirements; and a U.S. REIT’s failure to qualify for the favorable U.S. federal income tax treatment generally available to U.S. REITs could result in corporate-level taxation, significantly reducing the return on an investment to the Fund.

| Formidable Dividend and Income ETF | ETN Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETN Risk. ETNs are senior, unsecured, unsubordinated debt securities of an issuer that are designed to provide returns that are linked to a particular benchmark. ETNs do not provide principal protection and may not make periodic coupon payments. ETNs have a maturity date and generally are backed only by the creditworthiness of the issuer. As a result, ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due.
|
| Formidable Dividend and Income ETF | Depositary Receipts Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts. Depositary receipts are generally subject to the same risks that the foreign securities that they evidence or into which they may be converted are, and they may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.
|
| Formidable Dividend and Income ETF | Risk Of Highly Volatile Markets Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Highly Volatile Markets. The prices of the derivative instruments in which the Fund may invest, including options and volatility-linked exchange-traded products, can be highly volatile. Price movements of the derivative instruments in which the Fund is invested are influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments, and national and international political and economic events and policies. The Fund is also subject to the risk of failure of any of the exchanges on which its derivative instrument positions trade or failure of their clearinghouses.
|
| Formidable Dividend and Income ETF | Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. The Fund is subject to liquidity risk primarily due to its investments in derivatives. Investments in illiquid assets involve the risk that the Fund may be unable to sell such assets or sell them at a reasonable price. Derivatives, especially when traded in large amounts, may not always be liquid. In such cases, in volatile markets the Fund may not be able to close out a position without incurring a loss. Daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivatives may prevent profitable liquidation of positions, subjecting the Fund to potentially greater losses.
|
| Formidable Dividend and Income ETF | Rights And Warrants Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rights and Warrants Risk. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer. |
| Formidable Dividend and Income ETF | Mid Capitalization Stock Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid Capitalization Stock Risk. The value of mid capitalization company stocks or ETFs that invest in stocks of mid capitalization companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.
|
| Formidable Dividend and Income ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is a new ETF and has not yet commenced operations. As a new fund, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in the Fund’s shares.
|
| Formidable Dividend and Income 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. |
| Formidable Dividend and Income ETF | Risk Not Insured Depository Institution [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 FDIC or any government agency. |
| Formidable Fortress ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.
|
| Formidable Fortress ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market value of securities owned by the Fund may decline, at times sharply and unpredictably.
|
| Formidable Fortress ETF | Active Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk. The Adviser’s investment decisions about individual securities impact the Fund’s ability to achieve its investment objective. The Adviser’s judgments about the attractiveness and potential appreciation of particular investments in which the Fund invests may prove to be incorrect and there is no guarantee that the Adviser’s investment strategy will produce the desired results.
|
| Formidable Fortress ETF | Risk Of Other Equity Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Other Equity Securities. Other equity securities in which the Fund may invest include preferred securities, rights and warrants. •Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. •Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

| Formidable Fortress ETF | Risk Of Other Equity Securities, Preferred Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. |
| Formidable Fortress ETF | Risk Of Other Equity Securities, Rights And Warrants Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer. |
| Formidable Fortress ETF | ETF Structure Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to special risks, including: •Trading Issues Risk. Although it is expected that shares of the Fund will remain listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”), trading in Fund shares on the Exchange may be halted due to market conditions shares inadvisable, such as extraordinary market volatility. There can be no assurance that Fund shares will continue to meet the listing requirements of the Exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of the Fund. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund. This adverse effect on liquidity for the Fund’s shares in turn could lead to differences between the market price of the Fund’s shares and the underlying value of those Shares. •Market Price Variance Risk. The market prices of shares of the Fund will fluctuate in response to changes in the Fund’s net asset value (“NAV”) and supply and demand for Fund 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 Fund shares may trade at a discount to NAV. The market price of Shares may deviate from the value of the Fund’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 Fund bought or sold. •Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. The Fund has 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 the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. The Fund has 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 the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Formidable Fortress ETF | ETF Structure Risk, Costs Of Buying Or Selling Shares Of The Fund Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments. |
| Formidable Fortress ETF | Investment Company Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company Risk. An investment in other investment companies (including other exchange-traded products) is subject to the risks associated with those investment companies, which include, but are not limited to, the risk that such fund’s investment strategy may not produce the intended results; the risk that securities in such fund may underperform in comparison to the general securities markets or other asset classes; and the risk that the fund will be concentrated in a particular issuer, market, industry or sector, and therefore will be especially susceptible to loss due to adverse occurrences affecting that issuer, market, industry or sector. Moreover, the Fund will incur duplicative expenses from such investments, bearing its share of that fund’s expenses while also paying its own advisory fees and trading costs.
|
| Formidable Fortress ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The Fund may use derivative instruments such as put and call options on stocks and certain volatility-linked exchange-traded products. There is no guarantee that the use of these instruments by the Fund will work. The value of derivatives may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Other risks of investments in derivatives include imperfect correlation between the value of these instruments and the underlying assets; risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that offset gains in portfolio positions; and risks that the derivative transactions may not be liquid. The Fund’s use of derivatives may magnify losses for the Fund. If the Fund is not successful in employing such instruments in managing its portfolio, its performance will be worse than if it did not invest in such instruments. Successful use by the Fund of options will be subject to its ability to correctly predict movements in the direction of the securities generally or of a particular market segment. In addition, the Fund will pay commissions and other costs in connection with such investments, which may indirectly increase the Fund’s expenses and reduce the return. In utilizing certain derivatives, the Fund’s losses are potentially unlimited. Derivative instruments may also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Fund. The Fund has adopted policies and procedures pursuant to Rule 18f-4 under the Investment Company Act of 1940.
|
| Formidable Fortress ETF | Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of their underlying securities. Writing call options may reduce the Fund’s ability to profit from increases in the value of the Fund’s portfolio securities. When writing call options on a portfolio security, the Fund receives a premium; however, the premium may not be enough to offset a loss incurred by the Fund if the price of the portfolio security is above the strike price by an amount equal to or greater than the premium. The Fund’s option strategy is designed to provide the Fund with income by taking in options premiums, but it is not designed to mitigate losses to the Fund in the event of a market decline.
|
| Formidable Fortress ETF | FLEX Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Risk. The Fund may invest in 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.
|
| Formidable Fortress ETF | Large Capitalization Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Securities Risk. Investments in large capitalization securities as a group could fall out of favor with the market, causing the Fund to underperform investments that focus on small capitalization securities. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
|
| Formidable Fortress ETF | Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. To the extent the Fund invests in foreign securities, it may be subject to additional risks not typically associated with investments in domestic securities. These risks may include, among others, currency risk, country risks (political, diplomatic, regional conflicts, terrorism, war, social and economic instability, currency devaluations and policies that have the effect of limiting or restricting foreign investment or the movement of assets), different trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility.
|
| Formidable Fortress ETF | Leverage Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk. The Fund does not seek leveraged returns but as a result of the Fund’s use of certain derivatives it may create investment leverage. This means that the derivative position may provide the Fund with investment exposure greater than the value of the Fund’s investment in the derivative. As a result, these derivatives may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund.
|
| Formidable Fortress ETF | Issuer Non-Diversification Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer Non-Diversification Risk. The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than diversified funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.
|
| Formidable Fortress ETF | Investment Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Strategy Risk. The Fund’s investments in securities that the Adviser believes will perform well in a certain macroeconomic environment may not perform as expected. In addition, the Fund’s investment approach may be out of favor at times, causing it to underperform other portfolios that have a similar investment objective.
|
| Formidable Fortress ETF | Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Risk. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, as with any investment, you may lose some or all of your investment by investing in the Fund. |
| Formidable Fortress ETF | REITs Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs. Investing in real estate investment trusts (“REITs”) involves unique risks. When the Fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the Fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. U.S. REITs are subject to a number of highly technical tax-related rules and requirements; and a U.S. REIT’s failure to qualify for the favorable U.S. federal income tax treatment generally available to U.S. REITs could result in corporate-level taxation, significantly reducing the return on an investment to the Fund.
|
| Formidable Fortress ETF | ETN Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETN Risk. ETNs are senior, unsecured, unsubordinated debt securities of an issuer that are designed to provide returns that are linked to a particular benchmark. ETNs do not provide principal protection and may not make periodic coupon payments. ETNs have a maturity date and generally are backed only by the creditworthiness of the issuer. As a result, ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due.
|
| Formidable Fortress ETF | Depositary Receipts Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts. Depositary receipts are generally subject to the same risks that the foreign securities that they evidence or into which they may be converted are, and they may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.
|
| Formidable Fortress ETF | Risk Of Highly Volatile Markets Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Highly Volatile Markets. The prices of the derivative instruments in which the Fund may invest, including options and volatility-linked exchange-traded products, can be highly volatile. Price movements of the derivative instruments in which the Fund is invested are influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments, and national and international political and economic events and policies. The Fund is also subject to the risk of failure of any of the exchanges on which its derivative instrument positions trade or failure of their clearinghouses.
|
| Formidable Fortress ETF | Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. The Fund is subject to liquidity risk primarily due to its investments in derivatives. Investments in illiquid assets involve the risk that the Fund may be unable to sell such assets or sell them at a reasonable price. Derivatives, especially when traded in large amounts, may not always be liquid. In such cases, in volatile markets the Fund may not be able to close out a position without incurring a loss. Daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivatives may prevent profitable liquidation of positions, subjecting the Fund to potentially greater losses.
|
| Formidable Fortress ETF | Mid Capitalization Stock Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid Capitalization Stock Risk. The value of mid capitalization company stocks or ETFs that invest in stocks of mid capitalization companies may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.
|
| Formidable Fortress 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. |
| Formidable Fortress ETF | Risk Not Insured Depository Institution [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 FDIC or any government agency. |
