| Aptus Laddered Buffer ETF | Affiliated Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Affiliated Fund Risk. In managing the Fund, the Adviser has the ability to select each underlying buffer ETF in its laddered portfolio and substitute the Underlying ETFs with other Aptus-managed buffer ETFs that it believes will achieve the Fund’s investment objective. The Adviser may be subject to conflicts of interest in selecting Underlying ETFs and substituting Underlying ETFs with other ETFs because the Adviser receives advisory fees from the Underlying ETFs and other ETFs managed by the Adviser, which may be higher than the fees paid by other buffer ETFs. Additionally, an Underlying ETF may benefit from being selected in terms of enhanced liquidity and accumulation of assets. |
| Aptus Laddered Buffer ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Underlying ETFs will be successful in their strategy to buffer against SPY losses. Despite the intended buffer, the Fund may lose its entire investment in an Underlying ETF. Each Underlying ETF’s strategy seeks to deliver returns (before fees and expenses) that match the price return of SPY (up to the cap), while limiting downside losses, if shares are bought on the day on which the Underlying ETF enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. To the extent the Fund acquires shares of the Underlying ETFs in connection with creations of new shares of the Fund and during each rebalancing, the Fund typically will not acquire Underlying ETF shares on the first day of an Investment Period. Likewise, to the extent the Fund disposes of shares of the Underlying ETFs in connection with redemptions of shares of the Fund and during each rebalancing, any such dispositions typically will not occur on the last day of an Investment Period. In the event that the Fund acquires shares after the first day of an Investment Period or disposes of shares prior to the end of an Investment Period, the buffer that the Underlying ETF seeks to provide may not be available and the Fund may not get the full benefit of the buffer. If the Fund purchases Underlying ETF shares during an Investment Period at a time when the Underlying ETF has decreased in value by 15% or more from the value of the Underlying ETF on the first day of the Investment Period (the “Initial Underlying ETF Value”), the Fund’s buffer will essentially be zero (meaning the Fund can lose its entire investment). If the Fund purchases Underlying ETF shares at a time when the Underlying ETF has decreased in value by less than 15% from the Initial Underlying ETF Value, the Fund’s buffer will be reduced by the difference between the Initial Underlying ETF Value and the NAV of the Underlying ETF on the date the Fund purchases the shares. An investor like the Fund that holds Underlying ETF shares through multiple Investment Periods will be unable to recapture losses from prior Investment Periods because at the end of each Investment Period, a new buffer will be established based on the then current price of SPY and any losses experienced below the prior buffer will be locked in.
|
| Aptus Laddered Buffer ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Underlying ETF cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, an Underlying ETF’s cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. |
| Aptus Laddered Buffer ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. Each Underlying ETF’s strategy seeks to provide returns (before fees and expenses) that match the price return of SPY for shares acquired on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside cap. Because the Fund will acquire shares of the Underlying ETFs in connection with creations of new shares of the Fund and during each rebalance, the Fund typically will not acquire Underlying ETF shares on the first day of an Investment Period. Likewise, the Fund will dispose of shares of the Underlying ETFs in connection with redemptions of shares of the Fund and during each rebalance, and such disposals typically will not occur on the last day of an Investment Period. In the event that the Fund acquires Underlying ETF shares after the first day of an Investment Period and the Underlying ETF has risen in value to a level near to the cap, there may be little or no ability for the Fund to experience an investment gain on its shares (because the Fund’s potential gain will be limited to the difference between the Underlying ETF's NAV on the date the Fund purchases Underlying ETF shares and the cap), however, the Fund will remain vulnerable to downside risks. This could be true for all of the Underlying ETFs held by the Fund at a certain point in time severely limiting the Fund’s ability to participate in gains during that time. If SPY experiences gains during an Investment Period, an Underlying ETF will not participate in those gains beyond the cap. If the Fund buys Underlying ETF shares when the price exceeds the cap, the Fund will not experience any gain regardless of the performance of SPY. An investor like the Fund that holds Underlying ETF shares through multiple Investment Periods may fail to experience gains comparable to those of SPY over time because at the end of each Investment Period, a new cap will be established based on the then current price of SPY and any gains above the prior cap will be forfeit. Moreover, the annual imposition of a new cap on future gains may make it difficult to recoup any losses from prior Investment Periods such that, over multiple Investment Periods, the Underlying ETFs may have losses that exceed those of SPY. |
| Aptus Laddered Buffer ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Underlying ETF transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Underlying ETF. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. An Underlying ETF may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The OCC acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of an Underlying ETF to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, an Underlying ETF, and in turn, the Fund could suffer significant losses. |
| Aptus Laddered Buffer ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus Laddered Buffer ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Aptus Laddered Buffer ETF | ETF Risks, Authorized Participants, Market Makers, And Liquidity Providers Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Aptus Laddered Buffer ETF | ETF Risks, Costs Of Buying Or Selling Shares Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. |
| Aptus Laddered Buffer ETF | ETF Risks, Shares May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. |
| Aptus Laddered Buffer ETF | ETF Risks, Trading Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares. |
| Aptus Laddered Buffer ETF | FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by an Underlying ETF will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the share price of SPY. Factors that may influence the value of the FLEX Options, other than changes in the share price of SPY, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of SPY. |
| Aptus Laddered Buffer ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options held by an Underlying ETF are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of an Underlying ETF’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Underlying ETF shares and result in the Underlying ETF being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Aptus Laddered Buffer ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options held by an Underlying ETF will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of SPY. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Underlying ETF, the ability of the Underlying ETF to value the FLEX Options becomes more difficult and the judgment of the Underlying ETF’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Underlying ETF’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus Laddered Buffer ETF | Fund-Of-Defined Outcome Funds Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fund-of-Defined Outcome Funds Risk. Shareholders of the Fund will experience investment returns that are different than the investment returns provided by an Underlying ETF. The Fund does not itself pursue a defined outcome strategy, nor does the Fund itself provide a defined buffer against U.S. large cap ETF losses. Because the Fund will typically not purchase an Underlying ETF on the first day of an Outcome Period, it is not likely that the stated outcome of the Underlying ETF will be realized by the Fund. The Fund will be continuously exposed to the investment profiles of each of the Underlying ETFs during their respective Investment Periods. A purchaser of Shares will, therefore, have exposure to Underlying ETFs with differing profiles in terms of its upside performance availability to its cap and potential for downside protection to its buffer. The Fund may invest in an Underlying ETF at times when the Underlying ETF is experiencing little or no benefit to its cap or buffer. The Fund, with its aggregate exposure to each of the Underlying ETFs and its respective defined outcome profiles, may have investment returns that are inferior to that of any single Underlying ETF or group of Underlying ETFs over any given time period. Because the Fund may not be equally weighted on a continuous basis, the Fund may be exposed to one or more Underlying ETFs disproportionately when compared to other Underlying ETFs. In such circumstances, the Fund will be subject to the over-weighted performance of such Underlying ETF. As a shareholder in other ETFs, the Fund bears its proportionate share of each ETF’s expenses, subjecting Fund shareholders to duplicative expenses. |
| Aptus Laddered Buffer ETF | Investment Company Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company Risk. The risks of investing in investment companies, such as the Underlying ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. The Fund may be subject to regulatory limits with respect to the amount it can invest in other ETFs, which may adversely affect the Fund’s ability to achieve its investment objective. Investments in ETFs are also subject to the “ETF Risks” described above. |
| Aptus Laddered Buffer ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. Each Underlying ETF’s investment strategy is designed to deliver returns that match the share price return of SPY if Shares are bought on the day on which the Underlying ETF enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period subject to the cap. Because the Fund will acquire shares of the Underlying ETFs in connection with creations of new shares of the Fund and during each rebalance, the Fund typically will not acquire Underlying ETF shares on the first day of an Investment Period. Likewise, the Fund will dispose of shares of the Underlying ETFs in connection with redemptions of shares of the Fund and during each rebalance, and such disposals typically will not occur on the last day of an Investment Period. In the event the Fund acquires shares after the first day of an Investment Period or disposes of shares prior to the expiration of the Investment Period, the value of the Fund’s investment in Underlying ETF shares may not be buffered against a decline in the value of SPY and may not participate in a gain in the value of SPY for the Fund’s investment period. |
| Aptus Laddered Buffer ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. Each Underlying ETF invests in FLEX Options that reference the market price of SPY, which is comprised of the securities of large-capitalization companies. As a result, an Underlying ETF’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Aptus Laddered Buffer ETF | Limited Operating History Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Operating History Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Aptus Laddered Buffer ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund. |
| Aptus Laddered Buffer ETF | Market Fluctuation Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Fluctuation Tax Risk. The Fund may acquire shares of the Underlying ETFs in the open market. When the Fund sells shares of the Underlying ETFs in the open market, the Fund will recognize gain or loss on the disposition of the shares, which could have a negative impact on Fund returns. In addition, note that the Fund may, under certain circumstances, effect a portion of its creations and redemptions for cash rather than in-kind. If the Fund effects redemptions for cash, it may be required to sell shares of the Underlying ETFs in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute such shares only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares entirely in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind. The Fund’s use of cash for creations and redemptions could also result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. |
| Aptus Laddered Buffer ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent SPY invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. SPY may invest a significant portion of its assets in the following sector and, therefore, the performance of the Underlying ETFs, which invest substantially in FLEX Options that reference the market price of SPY, could be negatively impacted by events affecting this sector. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Underlying ETF’s investments. 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 foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile 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.

| Prospectus [Line Items] | |
| Risk [Text Block] | Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Underlying ETF’s investments. 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 foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile 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. |
| Aptus Laddered Buffer ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. Each Underlying ETF intends to qualify as a RIC; however, the federal income tax treatment of certain aspects of the proposed operations of the Underlying ETFs are not entirely clear. This includes the tax aspects of the Underlying ETFs’ options strategy, the hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, an Underlying ETF fails to qualify as a RIC under the applicable tax laws, the Underlying ETF would be taxed as an ordinary corporation, which could cause the Fund to lose its status as a RIC as well if there are no cure provisions available to the Fund. Similar to other ETFs, when an Underlying ETF disposes of appreciated property by distributing such appreciated property in-kind pursuant to redemption requests of AP shareholders under Section 852(b)(6) of the Code, the Underlying ETF does not expect to recognize any built-in gain in such appreciated property. The Underlying ETFs have received an opinion of special tax counsel to the Fund’s adviser regarding whether Section 852(b)(6) should be available when an Underlying ETF rebalances its portfolio and distributes appreciated portfolio positions. If the Internal Revenue Service (“IRS”) or a court were to disagree with an Underlying ETF’s position as to the applicability of this nonrecognition rule to the Underlying ETF’s dispositions, the Underlying ETF could be under-distributed with respect to its income or gains; potentially causing the Underlying ETF to fail to qualify as a RIC for such year, subjecting the Underlying ETF to tax, interest and penalties, and potentially causing the character of the amounts reported to shareholders to be incorrect. If, for any year, an Underlying ETF fails to qualify as a RIC, the Underlying ETF itself generally would be subject to regular corporate U.S. federal income tax, and distributions received by its shareholders, including the Fund, would be subject to further U.S. federal income tax. Alternatively, the Underlying ETF may be required to pay a deficiency dividend (without having received additional cash) and applicable interest, and such dividend would be paid to the then current shareholders of the Underlying ETF, including the Fund. Failure to comply with the requirements for qualification as a RIC would have significant negative economic consequences to the Underlying ETF’s shareholders and, in turn, the Fund and its shareholders. Failure by an Underlying ETF to qualify as a RIC could also cause the Fund to lose its status as a RIC as well, which could have significant negative economic consequences for the shareholders of the Fund.
|
| Aptus Laddered Buffer ETF | SPY Equity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | SPY Equity Risk. Because each Underlying ETF holds FLEX Options that reference SPY, each Underlying ETF has exposure to the equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. |
| Aptus Laddered Buffer ETF | SPY Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | SPY Risk. Each Underlying ETF invests in FLEX Options that reference SPY, which subjects the Underlying ETFs to certain of the risks of owning shares of an ETF as well as the types of instruments in which SPY invests. The value of SPY will fluctuate over time based on fluctuations in the values of the securities held by SPY, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to absence of an active market risk, premium/discount risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, fees and transaction expenses and other factors. In particular, each Underlying ETF’s value may not directly correlate to SPY because the FLEX Options are only exercisable on the expiration date and the fluctuating value of the FLEX Options will affect the Underlying ETF’s value. |
| Aptus Laddered Buffer ETF | Underlying ETF Exposure Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Exposure Risk. An investment in the Fund may provide returns that are lower than the returns that an investor could achieve by investing in one or more of the Underlying ETFs alone. Additionally, if one or more of the Underlying ETFs has exceeded its cap at the time that you invest in the Fund, you may derive no benefit from the Fund’s investment in that Underlying ETF until the next reset of the Underlying ETF. Likewise, if one or more of the Underlying ETFs has decreased in value below its buffer at the time that you invest in the Fund, you may derive no buffered protection from the Fund’s investment in that Underlying ETF. See “Buffered Loss Risk” and “Capped Upside Risk” above. The Fund does not itself pursue a structured outcome strategy and does not provide any buffer against Underlying ETF losses. |
| Aptus Laddered Buffer ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. |
| Aptus January Buffer ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price performance of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. An investor that holds Shares through multiple Investment Periods will be unable to recapture losses, if any, from prior Investment Periods because the Buffer resets for each new Investment Period and is established based on the then current price of the Underlying ETF. Accordingly, any losses experienced outside the prior Buffer will be locked in. |
| Aptus January Buffer ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. Unlike the Cap, the Buffer and the Underlying ETF will remain the same for each Investment Period. |
| Aptus January Buffer ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the share price performance of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in share price to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Aptus January Buffer ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses.
|
| Aptus January Buffer ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration 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. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. 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.

| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the share price of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the share price of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Aptus January Buffer ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus January Buffer ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the share price of the Underlying ETF and may not participate in a gain in the share price of the Underlying ETF up to the Cap for the investor’s investment period. |
| Aptus January Buffer ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund invests in FLEX Options that reference the market price of the Underlying ETF, which is comprised of the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Aptus January Buffer ETF | Limited Operating History Risk Member | |

| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio.

There can be no guarantee that the Fund will meet its investment objective. |
| Aptus January Buffer ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Underlying ETF invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Underlying ETF may invest a significant portion of its assets in the following sector and, therefore, the performance of the Fund, which invests substantially in FLEX Options that reference the market price of the Underlying ETF, could be negatively impacted by events affecting this sector. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. 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 foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile 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. |

| Aptus January Buffer ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated investment company” (“RIC”); however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period.Similar to other ETFs, when the Fund disposes of appreciated property by distributing such appreciated property in-kind pursuant to redemption requests of AP shareholders under Section 852(b)(6) of the Code, the Fund does not expect to recognize any built-in gain in such appreciated property. The Fund has received an opinion of special tax counsel to the Fund’s adviser regarding whether Section 852(b)(6) should be available when it rebalances the portfolio and distributes appreciated portfolio positions. If the Internal Revenue Service (“IRS”) or a court were to disagree with the Fund’s position as to the applicability of this nonrecognition rule to the Fund’s dispositions, the Fund could be under-distributed with respect to its income or gains; potentially causing the Fund to fail to qualify as a RIC for such year, subjecting the Fund to tax, interest and penalties, and potentially causing the character of the amounts reported to shareholders to be incorrect. If, for any year, the Fund fails to qualify as a RIC, the Fund itself generally would be subject to regular corporate U.S. federal income tax, and distributions received by its shareholders would be subject to further U.S. federal income tax. Alternatively, the Fund may be required to pay a deficiency dividend (without having received additional cash) and applicable interest, and such dividend would be paid to the then current shareholders of the Fund. Failure to comply with the requirements for qualification as a RIC would have significant negative economic consequences for the Fund’s shareholders. |
| Aptus January Buffer ETF | Cash Transaction Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Cash Transaction Risk. The Fund may effect all or a portion of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV.

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. |

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. |
| Aptus January Buffer ETF | ETF Risks, Shares Of The Fund May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |

| Aptus January Buffer ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus January Buffer ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |

| Aptus January Buffer 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. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Aptus April Buffer ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price performance of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. An investor that holds Shares through multiple Investment Periods will be unable to recapture losses, if any, from prior Investment Periods because the Buffer resets for each new Investment Period and is established based on the then current price of the Underlying ETF. Accordingly, any losses experienced outside the prior Buffer will be locked in. |
| Aptus April Buffer ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. Unlike the Cap, the Buffer and the Underlying ETF will remain the same for each Investment Period. |
| Aptus April Buffer ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the share price performance of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in share price to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares.
|
| Aptus April Buffer ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses.

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. |
| Aptus April Buffer ETF | ETF Risks, Costs Of Buying Or Selling Shares Of The Fund Risk 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. |
| Aptus April Buffer ETF | ETF Risks, Shares Of The Fund May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. |
| Aptus April Buffer ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus April Buffer ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |

| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. |
| Aptus April Buffer 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. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Aptus July Buffer ETF | Buffered Loss Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses. Despite the intended Buffer, a shareholder could lose their entire investment. The Fund’s strategy seeks to deliver returns that match the share price performance of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are bought on the day on which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of each Investment Period. In the event an investor purchases Shares after the date on which the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available and the investor may not get the full benefit of the Buffer. The Fund might not achieve its objective in certain circumstances. The Fund does not provide principal protection and an investor may experience significant losses on its investment, including loss of its entire investment. An investor that holds Shares through multiple Investment Periods will be unable to recapture losses, if any, from prior Investment Periods because the Buffer resets for each new Investment Period and is established based on the then current price of the Underlying ETF. Accordingly, any losses experienced outside the prior Buffer will be locked in. |
| Aptus July Buffer ETF | Cap Change Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cap Change Risk. A new Cap is established at the beginning of each Investment Period and is dependent on prevailing market conditions. As a result, the Cap may rise or fall from one Investment Period to the next and is unlikely to remain the same for consecutive Investment Periods. Unlike the Cap, the Buffer and the Underlying ETF will remain the same for each Investment Period. |
| Aptus July Buffer ETF | Capped Upside Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Capped Upside Risk. The Fund’s strategy seeks to provide returns that match those of the share price performance of the Underlying ETF for Shares purchased on the first day of an Investment Period and held for the entire Investment Period, subject to a pre-determined upside Cap. If an investor does not hold its Shares for an entire Investment Period, the returns realized by that investor may not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during an Investment Period, the Fund will not participate in those gains beyond the Cap. In the event an investor purchases Shares after the first day of an Investment Period and the Fund has risen in share price to a level near to the Cap, there may be little or no ability for that investor to experience an investment gain on their Shares. |
| Aptus July Buffer ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses.

| Aptus July Buffer ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks: ◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration 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. ◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings.

This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. ◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. 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.

| Aptus July Buffer ETF | FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the share price of the Underlying ETF. Factors that may influence the value of the FLEX Options, other than changes in the share price of the Underlying ETF, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the Underlying ETF. |
| Aptus July Buffer ETF | FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Aptus July Buffer ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus July Buffer ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Aptus July Buffer ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund invests in FLEX Options that reference the market price of the Underlying ETF, which is comprised of the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Aptus July Buffer ETF | Limited Operating History Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Operating History Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Aptus July Buffer ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio manager will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective. |
| Aptus July Buffer ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Underlying ETF invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Underlying ETF may invest a significant portion of its assets in the following sector and, therefore, the performance of the Fund, which invests substantially in FLEX Options that reference the market price of the Underlying ETF, could be negatively impacted by events affecting this sector. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. 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 foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile 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. |

| Aptus July Buffer ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated investment company” (“RIC”); however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. Similar to other ETFs, when the Fund disposes of appreciated property by distributing such appreciated property in-kind pursuant to redemption requests of AP shareholders under Section 852(b)(6) of the Code, the Fund does not expect to recognize any built-in gain in such appreciated property. The Fund has received an opinion of special tax counsel to the Fund’s adviser regarding whether Section 852(b)(6) should be available when it rebalances the portfolio and distributes appreciated portfolio positions. If the Internal Revenue Service (“IRS”) or a court were to disagree with the Fund’s position as to the applicability of this nonrecognition rule to the Fund’s dispositions, the Fund could be under-distributed with respect to its income or gains; potentially causing the Fund to fail to qualify as a RIC for such year, subjecting the Fund to tax, interest and penalties, and potentially causing the character of the amounts reported to shareholders to be incorrect. If, for any year, the Fund fails to qualify as a RIC, the Fund itself generally would be subject to regular corporate U.S. federal income tax, and distributions received by its shareholders would be subject to further U.S. federal income tax. Alternatively, the Fund may be required to pay a deficiency dividend (without having received additional cash) and applicable interest, and such dividend would be paid to the then current shareholders of the Fund. Failure to comply with the requirements for qualification as a RIC would have significant negative economic consequences for the Fund’s shareholders.

| Aptus July Buffer ETF | Cash Transaction Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transaction Risk. The Fund may effect all or a portion of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV. |

| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Aptus October Buffer ETF | FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus October Buffer ETF | Investment Period Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Period Risk. The Fund’s investment strategy is designed to deliver returns that match the share price return of the Underlying ETF if Shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of an Investment Period) and held until those FLEX Options expire at the end of the Investment Period. In the event an investor purchases Shares after the first day of an Investment Period or sells Shares prior to the expiration of the Investment Period, the value of that investor’s investment in Shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the Cap for the investor’s investment period. |
| Aptus October Buffer ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund invests in FLEX Options that reference the market price of the Underlying ETF, which is comprised of the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. |
| Aptus October Buffer ETF | Limited Operating History Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Operating History Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Aptus October Buffer ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio manager will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective. |
| Aptus October Buffer ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Underlying ETF invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Underlying ETF may invest a significant portion of its assets in the following sector and, therefore, the performance of the Fund, which invests substantially in FLEX Options that reference the market price of the Underlying ETF, could be negatively impacted by events affecting this sector. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. 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 foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile 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. |

| Aptus October Buffer ETF | Special Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Special Tax Risk. The Fund intends to qualify as a “regulated investment company” (“RIC”); however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, its hedging strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. Similar to other ETFs, when the Fund disposes of appreciated property by distributing such appreciated property in-kind pursuant to redemption requests of AP shareholders under Section 852(b)(6) of the Code, the Fund does not expect to recognize any built-in gain in such appreciated property. The Fund has received an opinion of special tax counsel to the Fund’s adviser regarding whether Section 852(b)(6) should be available when it rebalances the portfolio and distributes appreciated portfolio positions. If the Internal Revenue Service (“IRS”) or a court were to disagree with the Fund’s position as to the applicability of this nonrecognition rule to the Fund’s dispositions, the Fund could be under-distributed with respect to its income or gains; potentially causing the Fund to fail to qualify as a RIC for such year, subjecting the Fund to tax, interest and penalties, and potentially causing the character of the amounts reported to shareholders to be incorrect. If, for any year, the Fund fails to qualify as a RIC, the Fund itself generally would be subject to regular corporate U.S. federal income tax, and distributions received by its shareholders would be subject to further U.S. federal income tax. Alternatively, the Fund may be required to pay a deficiency dividend (without having received additional cash) and applicable interest, and such dividend would be paid to the then current shareholders of the Fund. Failure to comply with the requirements for qualification as a RIC would have significant negative economic consequences for the Fund’s shareholders.
|
| Aptus October Buffer ETF | Cash Transaction Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transaction Risk. The Fund may effect all or a portion of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV. |
| Aptus October Buffer ETF | ETF Risks, Authorized Participants ("APs"), Market Makers, And Liquidity Providers Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration 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. |
| Aptus October Buffer ETF | ETF Risks, Costs Of Buying Or Selling Shares Of The Fund Risk 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. |
| Aptus October Buffer ETF | ETF Risks, Shares Of The Fund May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices. |
| Aptus October Buffer ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Market risk is the risk that a particular security, or Shares in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates, and perceived trends in securities prices. Shares could decline in value or underperform other investments. In addition, local, regional, or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus October Buffer ETF | Underlying ETF Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Underlying ETF Risk. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF, as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to authorized participant concentration risk, market maker risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses, and other factors. |
| Aptus October Buffer ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. |
| Aptus October Buffer 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. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Aptus Drawdown Managed Equity ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus Drawdown Managed Equity ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Aptus Drawdown Managed Equity ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. ◦Communications Sector Risk. The Fund’s investments are exposed to issuers conducting business in the Communications Sector. The Communications Sector includes companies that facilitate communication and offer related content and information through various mediums. It includes telecom and media & entertainment companies including producers of interactive gaming products and companies engaged in content and information creation or distribution through proprietary platforms. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Communications Sector. The performance of companies operating in the Communications Sector has historically been closely tied to the performance of the overall economy, and also is affected by economic growth, consumer confidence, attitudes and spending. Increased sensitivity to short product cycles and aggressive pricing, challenges in bringing products to market and changes in demographics and consumer tastes also can affect the demand for, and success of, communication services products and services in the marketplace. ◦Consumer Sectors Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer staples sector, such as companies that produce or sell food, beverage, and drug retail or other household items, may be adversely impacted by changes in global and economic conditions, rising energy prices, and changes in the supply or price of commodities. Companies in the consumer discretionary sector, such as automobile, textile, retail, and media companies, depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. ◦Technology Sector Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a significant 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. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

| Aptus Drawdown Managed Equity ETF | Depositary Receipt Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. |
| Aptus Drawdown Managed Equity ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The Fund invests in options that derive their performance from the performance of an underlying reference asset. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their reference asset, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. |
| Aptus Drawdown Managed Equity ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Because of the Fund’s investment in ADRs, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. |
| Aptus Drawdown Managed Equity ETF | Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Capitalization Risk. ◦Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. ◦Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings. ◦Small-Capitalization Investing Risk. The Fund may invest in the securities of small-capitalization companies. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

| Aptus Drawdown Managed Equity ETF | Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk. Selling (writing) and buying options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to gain exposure that is significantly greater than the premium paid or received. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling an option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the underlying asset is below the strike price for a put option, or above the strike price for a call option, by an amount equal to or greater than the premium. Purchasing of put or call options involves the payment of premiums, which may adversely affect the Fund’s performance. Purchased put or call options may expire worthless resulting in the Fund’s loss of the premium it paid for the option. |
| Aptus Drawdown Managed Equity ETF | REIT Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |

The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Communications Sector. The performance of companies operating in the Communications Sector has historically been closely tied to the performance of the overall economy, and also is affected by economic growth, consumer confidence, attitudes and spending. Increased sensitivity to short product cycles and aggressive pricing, challenges in bringing products to market and changes in demographics and consumer tastes also can affect the demand for, and success of, communication services products and services in the marketplace.

| Aptus Drawdown Managed Equity ETF | Tail Hedge Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tail Hedge Risk. The Fund may purchase put options designed to mitigate the Fund’s exposure to significant declines in the broader U.S. equity market. However, there is a risk that the Fund will experience a loss as a result of engaging in such options transactions. Moreover, there can be no assurance that the tail hedge will be successful in protecting against all or any declines in the value of the Fund’s portfolio because the amount of protection provided by the put options purchased by the Fund and the price of such protection will be dictated by prevailing market sentiment at the time the tail hedge is triggered. Additionally, the tail hedge will not protect against declines in the value of the Fund’s portfolio where such declines are based on factors other than general stock market fluctuations. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk. The use of derivatives strategies, such as writing (selling) and purchasing options, involves complex rules that will determine for income tax purposes the amount, character and timing of recognition of the gains and losses the Fund realizes in connection therewith. The Fund expects to generate premiums from its sale of options. These premiums typically will result in short-term capital gains for federal income tax purposes. In addition, equity securities that are hedged with put options may not be eligible for long-term capital gains tax treatment. The Fund is not designed for investors seeking a tax efficient investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |

| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Aptus Collared Investment Opportunity ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. ◦Communications Sector Risk. The Fund’s investments are exposed to issuers conducting business in the Communications Sector. The Communications Sector includes companies that facilitate communication and offer related content and information through various mediums. It includes telecom and media & entertainment companies including producers of interactive gaming products and companies engaged in content and information creation or distribution through proprietary platforms. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Communications Sector. The performance of companies operating in the Communications Sector has historically been closely tied to the performance of the overall economy, and also is affected by economic growth, consumer confidence, attitudes and spending. Increased sensitivity to short product cycles and aggressive pricing, challenges in bringing products to market and changes in demographics and consumer tastes also can affect the demand for, and success of, communication services products and services in the marketplace. ◦Consumer Sectors Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer staples sector, such as companies that produce or sell food, beverage, and drug retail or other household items, may be adversely impacted by changes in global and economic conditions, rising energy prices, and changes in the supply or price of commodities. Companies in the consumer discretionary sector, such as automobile, textile, retail, and media companies, depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. ◦Technology Sector Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a significant 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. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

| Risk [Text Block] | Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. |
| Aptus Collared Investment Opportunity ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The Fund invests in options that derive their performance from the performance of an underlying reference asset. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their reference asset, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. |
| Aptus Collared Investment Opportunity ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Because of the Fund’s investment in ADRs, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. |
| Aptus Collared Investment Opportunity ETF | Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Capitalization Risk. ◦Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. ◦Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings. ◦Small-Capitalization Investing Risk. The Fund may invest in the securities of small-capitalization companies. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

| Risk [Text Block] | REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |

| Aptus Collared Investment Opportunity ETF | Collared Options Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Collared Options Strategy Risk. Selling (writing) and buying options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to gain exposure that is significantly greater than the premium paid or received. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the underlying security, which may be magnified by certain features of the options. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the underlying security is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s underlying security, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the underlying security and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying security. The Fund’s use of the collared options strategy may reduce the Fund’s ability to profit from increases in the value of the underlying securities. If the price of the underlying security of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the underlying security instead of using options. Similarly, if the price of the underlying security of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the underlying security instead of using options.

The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Investments in foreign securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in foreign securities may be subject to risk of loss due to differences in accounting, auditing, and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital. Investments in foreign securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks.

The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options.

In addition, to the extent a written option that is part of an option spread strategy is exercised, the corresponding option purchased by the Fund to mitigate losses as part of an option spread strategy is not expected to offset all losses from the written option. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Securities Risk. The Fund invests indirectly in fixed income securities through investments in Underlying Bond ETFs, which involve certain risks, including: ◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer. ◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly. ◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall. ◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets. ◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

| Aptus Defined Risk ETF | Government Obligations Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Government Obligations Risk. The Fund may invest in Underlying Bond ETFs that invest in government obligations as part of their principal investment strategies. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law, such as Fannie Mae and Freddie Mac. Securities issued by Fannie Mae and Freddie Mac have historically been supported only by the discretionary authority of the U.S. government. While the U.S. government provides financial support to various U.S. government-sponsored agencies and instrumentalities, such as Fannie Mae and Freddie Mac, no assurance can be given that it will always do so. In September 2008, at the direction of the U.S. Department of the Treasury, Fannie Mae and Freddie Mac were placed into conservatorship under the Federal Housing Finance Agency (“FHFA”), an independent regulator, and they remain in such status as of the date of this Prospectus. The U.S. government also took steps to provide additional financial support to Fannie Mae and Freddie Mac. |
| Aptus Defined Risk ETF | Government Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Government Securities Risk. The Fund may invest in Underlying Bond ETFs that invest in government securities as part of their principal investment strategies. The Fund invests in U.S. Treasury obligations and securities issued or guaranteed by the U.S. Treasury. U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Some GSE securities may not be backed by the full faith and credit of the U.S. government, such as those issued by Freddie Mac, Fannie Mae, FHLBanks, and Farmer Mac. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in GSE securities that are supported by the full faith and credit of the U.S. Government, such as those issued by the Government National Mortgage Association (Ginnie Mae). |
| Aptus Defined Risk ETF | Mortgage- And Asset-Backed Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage- and Asset-Backed Securities Risk. The Fund may invest in Underlying Bond ETFs that principally invest in mortgage- and asset-backed securities. Such securities are subject to credit, interest rate, prepayment, and extension risks (see “Fixed Income Securities Risk” above). These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates may quickly and significantly reduce the value of certain mortgage-backed securities.
|
| Aptus Defined Risk ETF | Other Investment Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Other Investment Companies Risk. The risks of investing in investment companies, such as the Underlying Bond ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. The Fund may be subject to statutory limits with respect to the amount it can invest in other ETFs, which may adversely affect the Fund’s ability to achieve its investment objective. Investments in ETFs are also subject to the “ETF Risks” described above. |

| Opus Small Cap Value ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Opus Small Cap Value ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Opus Small Cap Value ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. ◦Consumer Sectors Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer staples sector, such as companies that produce or sell food, beverage, and drug retail or other household items, may be adversely impacted by changes in global and economic conditions, rising energy prices, and changes in the supply or price of commodities. Companies in the consumer discretionary sector, such as automobile, textile, retail, and media companies, depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. ◦Financials Sector Risk. This sector, which includes banks, insurance companies, and financial service firms, can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Banks, in particular, are subject to volatile interest rates, severe price competition, and extensive government oversight and regulation, which may limit certain economic activities available to banks, impact their fees and overall profitability, and establish capital maintenance requirements. In addition, banks may have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry. Insurance companies are subject to similar risks as banks, including adverse economic conditions, changes in interest rates, increased competition and government regulation, but insurance companies are more at risk from changes in tax law, government imposed premium rate caps, and catastrophic events, such as earthquakes, floods, hurricanes and terrorist acts. This sector has experienced significant losses in the recent past, and the impact of higher interest rates, more stringent capital requirements, and of recent or future regulation on any individual financial company, or on the sector as a whole, cannot be predicted. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in the financial sector and have caused significant losses. ◦Industrials Sector Risk. The industrials sector can be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, tariffs and trade barriers, and tax and governmental regulatory policies. As the demand for, or prices of, industrials increase, the value of the Fund’s investments generally would be expected to also increase. Conversely, declines in the demand for, or prices of, industrials generally would be expected to contribute to declines in the value of such securities. Such declines may occur quickly and without warning and may negatively impact the value of the Fund and your investment.

| Opus Small Cap Value ETF | Depositary Receipt Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. |
| Opus Small Cap Value ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Because of the Fund’s investment in ADRs, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. |
| Opus Small Cap Value ETF | REIT Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |

| Opus Small Cap Value ETF | IPO Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | IPO Risk. The Fund may invest in securities offered in an IPO or in companies that have recently completed an IPO. The market value of IPO shares can have significant volatility due to factors such as the absence of a prior public market, unseasoned trading, a small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs, and the Fund may lose money on an investment in such securities. |

| Opus Small Cap Value ETF | Small-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small-Capitalization Investing Risk. The Fund may invest in the securities of small-capitalization companies. As a result, the Fund may be more volatile than funds that invest in larger, more established companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Small-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings. |
| Opus Small Cap Value ETF | Value-Style Investing Risk Member | |

| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. |

The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices.

This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because the Fund’s investments have exposure to securities that may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained.

| Aptus International Enhanced Yield ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives, such as the options, futures contracts, and swaps in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. ◦Futures Contracts Risk. The Fund will be exposed to the risks of futures contracts through the STSs implemented by the Fund’s total return swaps. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the risks associated with all derivatives, the prices of futures can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the initial investment in such contracts and could be unlimited. ◦Options Risk. The Fund will be exposed to the risks of call and put options through the STSs implemented by the Fund’s total return swaps. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. ◦Swap Risk. The Fund may enter into derivatives called swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter (“OTC”) market, which generally has less transparency than exchange-traded derivatives instruments. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty.

| Aptus International Enhanced Yield ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Companies in many foreign markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in the U.S., and as a result, information about the securities in which the Fund invests may be less reliable or complete. Foreign markets often have less reliable securities valuations and greater risk associated with the custody of securities than the U.S. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. |
| Aptus International Enhanced Yield ETF | Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Market Capitalization Risk. ◦Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. ◦Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. Mid-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings.

| Prospectus [Line Items] | |
| Risk [Text Block] | Other Investment Companies Risk. The risks of investing in other ETFs typically reflect the risks associated with the investment strategies of the other ETFs and the types of instruments in which the other ETFs invest. By investing in another ETF, the Fund becomes a shareholder of that ETF and bears its proportionate share of the fees and expenses of the other ETF. The Fund may be subject to statutory limits with respect to the amount it can invest in other ETFs, which may adversely affect the Fund’s ability to achieve its investment objective. Investments in ETFs are also subject to the “ETF Risks” described above. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value. |
| Aptus International Enhanced Yield ETF | Currency Exchange Rate Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Exchange Rate Risk. The Fund invests primarily in other ETFs that have exposure to securities denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. Less information may be available about companies in emerging markets than in developed markets because such emerging markets companies may not be subject to accounting, auditing, and financial reporting standards or to other regulatory practices required by U.S. companies. |
| Aptus International Enhanced Yield ETF | ETF Risks, Cash Redemption Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. |

Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Fund’s exposure to the other risks described herein will likely increase. Each of the foregoing may negatively impact the Fund’s investments. |
| Aptus International Enhanced Yield ETF | Return Of Capital Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Return of Capital Risk. The Fund expects to make distributions regardless of its performance. 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.

| Aptus Enhanced Yield ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund. In addition, the Fund does not guarantee and there can be no assurance that distributions will always be paid or will be paid at a relatively stable level in line with the Adviser’s internal targets. |
| Aptus Enhanced Yield ETF | Cash Transaction Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Transaction Risk. The Fund may effect all or a portion of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV.
|
| Aptus Enhanced Yield ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives, such as the options, futures contracts, and swaps in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. ◦Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. ◦FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. Factors that may influence the value of the FLEX Options, other than changes in the value of the underlying asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the underlying asset. ◦FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. ◦FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. ◦Futures Contracts Risk. The Fund will be exposed to the risks of futures contracts through the STSs implemented by the Fund’s total return swaps. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the risks associated with all derivatives, the prices of futures can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the initial investment in such contracts and could be unlimited. ◦Options Risk. The Fund will be exposed to the risks of call and put options through the STSs implemented by the Fund’s total return swaps. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. ◦Swap Risk. The Fund may enter into derivatives called swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter (“OTC”) market, which generally has less transparency than exchange-traded derivatives instruments. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty.

| Aptus Enhanced Yield ETF | Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk. The Fund may dispose of appreciated derivative holdings by distributing such positions in-kind pursuant to redemption requests. Under the Code, the distribution of appreciated property pursuant to a redemption request enables a RIC to not recognize any built-in gain in such appreciated property. If the IRS disagrees with the Fund’s position as to the applicability of this non-recognition rule to the Fund’s disposition of derivatives, the Fund could be required to recognize significant amounts of additional income and gains that would need to have been distributed to shareholders of the Fund to avoid incurring entity level income tax and potentially excise taxes. In addition, the IRS could seek to recharacterize any such capital gains as ordinary income. Failure to distribute sufficient amounts of income could cause the Fund to lose its tax-favored status as RIC and could expose the Fund to penalties by the IRS for incorrectly reporting the character of any distributions that were made to shareholders. If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. Failure to comply with the requirements for qualification as a RIC would have significant negative tax consequences to Fund shareholders. |
| Aptus Enhanced Yield ETF | Fixed Income Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Securities Risk. The Fund invests in fixed income securities. Fixed income securities, such as bonds, involve certain risks, which include: ◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer. ◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates, which may increase interest rate risk. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.

| Prospectus [Line Items] | |
| Risk [Text Block] | Government Obligations Risk. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law, such as Fannie Mae and Freddie Mac. Securities issued by Fannie Mae and Freddie Mac have historically been supported only by the discretionary authority of the U.S. government. While the U.S. government provides financial support to various U.S. government-sponsored agencies and instrumentalities, such as Fannie Mae and Freddie Mac, no assurance can be given that it will always do so. In September 2008, at the direction of the U.S. Department of the Treasury, Fannie Mae and Freddie Mac were placed into conservatorship under the Federal Housing Finance Agency (“FHFA”), an independent regulator, and they remain in such status as of the date of this Prospectus. The U.S. government also took steps to provide additional financial support to Fannie Mae and Freddie Mac. |
| Aptus Enhanced Yield ETF | Government Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | •Government Securities Risk. The Fund invests in U.S. Treasury obligations and securities issued or guaranteed by the U.S. Treasury. U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Some GSE securities may not be backed by the full faith and credit of the U.S. government, such as those issued by Freddie Mac, Fannie Mae, FHLBanks, and Farmer Mac. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in GSE securities that are supported by the full faith and credit of the U.S. Government, such as those issued by the Government National Mortgage Association (Ginnie Mae). |

| Risk [Text Block] | Options Risk. The Fund will be exposed to the risks of call and put options through the STSs implemented by the Fund’s total return swaps. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. |
| Aptus Enhanced Yield ETF | Derivatives Risk, Swap Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Swap Risk. The Fund may enter into derivatives called swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter (“OTC”) market, which generally has less transparency than exchange-traded derivatives instruments. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty. |
| Aptus Enhanced Yield ETF | ETF Risks, Cash Redemption Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. |
| Aptus Enhanced Yield ETF | Return Of Capital Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Return of Capital Risk. The Fund expects to make distributions regardless of its performance. 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. |
| Aptus Enhanced Yield ETF | Volatility Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Volatility Investing Risk. Significant short-term price movements could adversely impact the performance of the Fund, including any investments that are tied to volatility indexes or volatility-based derivative instruments, such as VIX futures contracts or options. Investments linked to equity market volatility, particularly VIX Index futures contracts or VIX Index options that are close to expiration, can be highly volatile and may experience large losses. |
| Aptus Enhanced Yield ETF | Box Spread Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Box Spread Risk. A box spread is the combination of a synthetic long position coupled with an offsetting synthetic short position through a combination of options contracts on an underlying or reference asset such as index, equity security or ETF with the same expiration date. A box spread typically consists of four option positions, two of which represent the synthetic long and two representing the synthetic short. If one or more of these individual option positions are modified or closed separately prior to the option contract’s expiration, then the box spread may no longer effectively eliminate risk tied to underlying asset’s movement. Furthermore, the box spread’s value is derived in the market and is in part, based on the time until the options comprising the box spread expire and the prevailing market interest rates. Although the Fund may hold a box spread until close to expiry, if the Fund were to sell a box spread prior to its expiration, then the Fund may incur a loss. The Fund’s ability to profit from box spreads is dependent on the availability and willingness of other market participants to sell box spreads to the Fund at competitive prices. |
| Aptus Enhanced Yield ETF | Derivatives Risk, Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Aptus Enhanced Yield ETF | Derivatives Risk, FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. Factors that may influence the value of the FLEX Options, other than changes in the value of the underlying asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the underlying asset. |
| Aptus Enhanced Yield ETF | Derivatives Risk, FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |
| Aptus Enhanced Yield ETF | Derivatives Risk, FLEX Options Valuation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus Enhanced Yield ETF | Derivatives Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Tax Risk. The Fund may enter into various transactions for which there is a lack of clear guidance under the Internal Revenue Code of 1986, as amended (the “Code”), which may affect the taxation of the Fund. In particular, the use of certain derivatives may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, to suspend or eliminate holding periods of positions, and/or to defer realized losses, potentially increasing the amount of taxable distributions, and of ordinary income distributions in particular. The Fund’s use of derivatives may be limited by the requirements for taxation as a regulated investment company (“RIC”). In addition, the federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the Internal Revenue Service (the “IRS”). |
| Aptus Enhanced Yield ETF | High Portfolio Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect. |
| Aptus Enhanced Yield ETF | U.S. Treasury Security Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Security Risk. The Fund has exposure to U.S. Treasuries, which are debt instruments issued by the U.S. Department of Treasury and are backed by the full faith and credit of the United States government. The market prices for U.S. Treasuries will fluctuate and are not guaranteed. |
| Aptus Enhanced Yield ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. |
| Aptus Large Cap Enhanced Yield ETF | Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. |
| Aptus Large Cap Enhanced Yield ETF | Equity Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk. Equity securities may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. |
| Aptus Large Cap Enhanced Yield ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

There can be no assurance that an active trading market for such Shares will develop or be maintained.

| Aptus Large Cap Enhanced Yield ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund. In addition, the Fund does not guarantee and there can be no assurance that distributions will always be paid or will be paid at a relatively stable level in line with the Adviser’s internal targets. |
| Aptus Large Cap Enhanced Yield ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The trading prices of debt securities and other instruments fluctuate in response to a variety of factors. 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. |
| Aptus Large Cap Enhanced Yield ETF | Depositary Receipt Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares. |
| Aptus Large Cap Enhanced Yield ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives, such as the options, futures contracts, and swaps in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. ◦Futures Contracts Risk. The Fund will be exposed to the risks of futures contracts through the STSs implemented by the Fund’s total return swaps. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the risks associated with all derivatives, the prices of futures can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the initial investment in such contracts and could be unlimited. ◦Options Risk. The Fund will be exposed to the risks of call and put options through the STSs implemented by the Fund’s total return swaps. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. ◦Swap Risk. The Fund may enter into derivatives called swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter (“OTC”) market, which generally has less transparency than exchange-traded derivatives instruments. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty.

| Aptus Large Cap Enhanced Yield ETF | Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. Because of the Fund’s investment in ADRs, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. |
| Aptus Large Cap Enhanced Yield ETF | Market Capitalization Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Capitalization Risk. ◦Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

| Aptus Large Cap Enhanced Yield ETF | REIT Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income. |
| Aptus Large Cap Enhanced Yield ETF | Other Investment Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Other Investment Companies Risk. The risks of investing in other ETFs typically reflect the risks associated with the investment strategies of the other ETFs and the types of instruments in which the other ETFs invest. By investing in another ETF, the Fund becomes a shareholder of that ETF and bears its proportionate share of the fees and expenses of the other ETF. The Fund may be subject to statutory limits with respect to the amount it can invest in other ETFs, which may adversely affect the Fund’s ability to achieve its investment objective. Investments in ETFs are also subject to the “ETF Risks” described above. |

The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. |

| Risk [Text Block] | Return of Capital Risk. The Fund expects to make distributions regardless of its performance. 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] | High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders.

| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading.

(the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Risk [Text Block] | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. |
| Aptus Large Cap Upside ETF | ETF Risks, Shares May Trade At Prices Other Than NAV Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. |

| Aptus Large Cap Upside ETF | Large-Capitalization Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. |
| Aptus Large Cap Upside ETF | Limited Operating History Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Limited Operating History Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Aptus Large Cap Upside ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund. |
| Aptus Large Cap Upside ETF | Derivatives Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives, such as the options, futures contracts, and swaps in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives. ◦Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. ◦FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. Factors that may influence the value of the FLEX Options, other than changes in the value of the underlying asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the underlying asset. ◦FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. ◦FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. Futures Contracts Risk. A decision as to whether, when, and how to use futures involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the risks associated with all derivatives, the prices of futures can be highly volatile, using futures can lower total return, and the potential loss from futures can exceed the Fund’s initial investment in such contracts and could be unlimited. ◦Options Risk. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. ◦Swap Risk. The Fund may enter into derivatives called swaps. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty.

Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. |
| Aptus Large Cap Upside ETF | Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk. The Fund may dispose of appreciated derivative holdings by distributing such positions in-kind pursuant to redemption requests. Under the Code, the distribution of appreciated property pursuant to a redemption request enables a RIC to avoid recognizing any built-in gain in such appreciated property. If the IRS disagrees with the Fund’s position as the applicability of this non-recognition rule to the Fund’s disposition of derivatives, the Fund could be required to recognize significant amounts of additional income and gains that would need to have been distributed to shareholders of the Fund to avoid incurring entity level income tax and potentially excise taxes. Failure to distribute sufficient amounts of income could cause the Fund to lose its tax-favored status as RIC. If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. Failure to comply with the requirements for qualification as a RIC would have significant negative tax consequences to Fund shareholders. |
| Aptus Large Cap Upside ETF | Other Investment Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Other Investment Companies Risk. The risks of investing in other investment companies, such as ETFs, typically reflect the risks of the types of instruments in which the investment company invests. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the investment company. As a result, an investment by the Fund in an investment company could cause the Fund’s operating expenses (taking into account indirect expenses such as the fees and expenses of the investment company) to be higher and, in turn, performance to be lower than if it were to invest directly in the instruments underlying the investment company. Investments in ETFs are also subject to the “ETF Risks” described above. |

| Aptus Large Cap Upside ETF | Derivatives Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Tax Risk. The Fund may enter into various transactions for which there is a lack of clear guidance under the Internal Revenue Code of 1986, as amended (the “Code”), which may affect the taxation of the Fund. In particular, the use of certain derivatives may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, to suspend or eliminate holding periods of positions, and/or to defer realized losses, potentially increasing the amount of taxable distributions, and of ordinary income distributions in particular. The Fund’s use of derivatives may be limited by the requirements for taxation as a regulated investment company (“RIC”). In addition, the federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the Internal Revenue Service (the “IRS”). |
| Aptus Large Cap Upside ETF | High Portfolio Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect. |
| Aptus Large Cap Upside ETF | U.S. Treasury Security Risk Member | |

| Aptus Large Cap Upside 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. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
| Aptus Deferred Income ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. ◦Trading. Although Shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

| Risk [Text Block] | Cash Transaction Risk. The Fund may effect all or a portion of its creations and redemptions for cash, rather than in-kind securities. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV. |

If the IRS disagrees with the Fund’s position as to the applicability of this non-recognition rule to the Fund’s disposition of derivatives, the Fund could be required to recognize significant amounts of additional income and gains that would need to have been distributed to shareholders of the Fund to avoid incurring entity level income tax and potentially excise taxes. In addition, the IRS could seek to recharacterize any such capital gains as ordinary income. Failure to distribute sufficient amounts of income could cause the Fund to lose its tax-favored status as RIC and could expose the Fund to penalties by the IRS for incorrectly reporting the character of any distributions that were made to shareholders. If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. Failure to comply with the requirements for qualification as a RIC would have significant negative tax consequences to Fund shareholders. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Securities Risk. The Fund utilizes derivatives that may provide economic exposure equivalent to fixed income securities, which in turn involve certain risks, including: ◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income. ◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer. ◦Duration Risk. Prices of fixed income securities with longer durations are more sensitive to interest rate changes than those with shorter durations. ◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly. ◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall. ◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets. ◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

| Aptus Deferred Income ETF | Derivatives Risk, Options Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ◦Options Risk. Purchasing and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. Additionally, the value of the option may be lost if the Adviser fails to exercise such option at or prior to its expiration. Further, writing option contracts can result in losses that exceed the seller’s initial investment and may lead to additional turnover and higher tax liability. The Fund will incur a loss as a result of writing (selling) options if the price of the written option instrument increases in value between the date the Fund writes the option and the date on which the Fund purchases an offsetting position or exits the option. |
| Aptus Deferred Income ETF | Derivatives Risk, Swap Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Swap Risk. The Fund may enter into derivatives called swaps. Risks associated with swap agreements include failure of the counterparties to perform under the contract’s terms, changes in the returns of the underlying instruments, and the possible lack of liquidity with respect to the swap agreements. The Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the bankruptcy or default of a swap agreement counterparty. |
| Aptus Deferred Income ETF | Box Spread Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Box Spread Risk. A box spread is the combination of a synthetic long position coupled with an offsetting synthetic short position through a combination of options contracts on an underlying or reference asset such as index, equity security or ETF with the same expiration date. A box spread typically consists of four option positions two of which represent the synthetic long and two representing the synthetic short. If one or more of these individual option positions are modified or closed separately prior to the option contract’s expiration, then the box spread may no longer effectively eliminate risk tied to underlying asset’s movement. Furthermore, the box spread’s value is derived in the market and is in part, based on the time until the options comprising the box spread expire and the prevailing market interest rates. Although the Fund may hold a box spread until close to expiry, if the Fund were to sell a box spread prior to its expiration, then the Fund may incur a loss. The Fund’s ability to profit from box spreads is dependent on the availability and willingness of other market participants to sell box spreads to the Fund at competitive prices. |
| Aptus Deferred Income ETF | Derivatives Risk, Counterparty Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Options Clearing Corporation (“OCC”) acts as guarantor and central counterparty with respect to FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. |
| Aptus Deferred Income ETF | Derivatives Risk, FLEX Options Correlation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. Factors that may influence the value of the FLEX Options, other than changes in the value of the underlying asset, may include interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, and changing volatility levels of the underlying asset. |
| Aptus Deferred Income ETF | Derivatives Risk, FLEX Options Liquidity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Liquidity Risk. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. The trading in FLEX Options may be less deep and liquid than the market for certain other securities. FLEX Options may be less liquid than certain non-customized options. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | FLEX Options Valuation Risk. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the underlying asset. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund’s investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust) may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. |
| Aptus Deferred Income ETF | Derivatives Tax Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Tax Risk. The Fund may enter into various transactions for which there is a lack of clear guidance under the Internal Revenue Code of 1986, as amended (the “Code”), which may affect the taxation of the Fund. In particular, the use of certain derivatives may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, to suspend or eliminate holding periods of positions, and/or to defer realized losses, potentially increasing the amount of taxable distributions, and of ordinary income distributions in particular. The Fund’s use of derivatives may be limited by the requirements for taxation as a regulated investment company (“RIC”). In addition, the federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the Internal Revenue Service (the “IRS”). |
| Aptus Deferred Income ETF | High Portfolio Turnover Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect. |
| Aptus Deferred Income ETF | U.S. Treasury Security Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Treasury Security Risk. The Fund may have exposure to U.S. Treasuries, which are debt instruments issued by the U.S. Department of Treasury and are backed by the full faith and credit of the United States government. The market prices for U.S. Treasuries will fluctuate and are not guaranteed. |
| Aptus Deferred Income ETF | Deferred Income Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Deferred Income Strategy Risk. Although the Fund seeks to provide a tax-efficient return stream by employing a strategy that seeks to defer the current recognition of income and gains, the Fund may not be able to defer such income and gains in a tax-efficient manner, the Fund may fail to achieve beneficial tax rates on the Fund’s capital gains, or U.S. tax laws and/or government regulations may change in such a manner so as to mitigate or eliminate tax benefits from deferred income. There are no assurances that the Fund’s investment strategies will enable it to defer the recognition of income and gains. |

| Aptus Deferred Income 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. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. |
