ETF Risks Member
Prospectus [Line Items]
Risk [Text Block]	ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks: •Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has only a limited number of institutional investors (known as “Authorized Participants” or “APs”) that are authorized to purchase and redeem shares directly from the Fund. 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 the Fund’s net asset value (“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. This may lead to the widening of bid/ask spreads quoted throughout the day. •Costs of Buying or Selling Shares. 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 may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments. This may lead to the widening of bid/ask spreads quoted throughout the day. •Shares 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. Although it is expected that the market price of shares of the Fund 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. This may lead to the widening of bid/ask spreads quoted throughout the day. Because securities held by the Fund 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 of the Fund are listed for trading on the NYSE Arca (the “Exchange”), there can be no assurance that an active trading market for shares will develop or be maintained or that shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for shares of the Fund may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Fund’s shares, in turn, can lead to differences between the market price of the Fund’s shares and the underlying value of those shares. In addition, trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. This may lead to the widening of bid/ask spreads quoted throughout the day. •Early Close/Trading Halt. An exchange or market may close early or issue trading halts on specific securities or financial instruments. The ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which the Fund’s shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. This may lead to the widening of bid/ask spreads quoted throughout the day. •Listing Standards Risk. The Fund is required to comply with listing requirements adopted by the listing exchange. Non-compliance with such requirements may result in the Fund's shares being delisted by the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders.

Risk [Text Block]	Early Close/Trading Halt. An exchange or market may close early or issue trading halts on specific securities or financial instruments. The ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which the Fund’s shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments.

Risk [Text Block]	Listing Standards Risk. The Fund is required to comply with listing requirements adopted by the listing exchange. Non-compliance with such requirements may result in the Fund's shares being delisted by the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders.
New Fund Risk Member
Prospectus [Line Items]
Risk [Text Block]	New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
Newer Adviser Risk Member
Prospectus [Line Items]
Risk [Text Block]	Newer Adviser Risk. The Adviser has not previously served as an adviser to a registered investment company. As a result, there is no long-term track record of the Adviser serving as an adviser to a registered investment company against which an investor may judge the Adviser and it is possible the Adviser may not achieve the Fund’s intended investment objective.
Active Management Risk Member
Prospectus [Line Items]
Risk [Text Block]	Active Management Risk. Active management by the Adviser in selecting and maintaining a portfolio of securities that will achieve the Fund’s investment objective could cause the Fund to underperform compared to other funds having similar investment objectives. If the market advances during periods when the Fund is holding a large cash position, the Fund will likely miss out on gains or underperform the market as compared to if the Fund had been more fully invested.
Asset Allocation Risk Member
Prospectus [Line Items]
Risk [Text Block]	Asset Allocation Risk: The Fund’s investment performance depends upon the successful allocation by the Adviser of the Fund’s assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser’s allocation techniques and decisions will produce the desired results. The Adviser’s selection and weighting of asset classes may cause the Fund to underperform other funds with a similar investment objective.
Foreign Investments And Emerging Markets Risk Member
Prospectus [Line Items]
Risk [Text Block]	Foreign Investments and Emerging Markets Risk. Securities of non-U.S. issuers, including those located in foreign countries, may involve special risks caused by foreign political, social and economic factors, including exposure to currency fluctuations, less liquidity, less developed and less efficient trading markets, political instability and less developed legal and auditing standards. These risks are heightened for investments in issuers organized or operating in developing countries.
Currency And Foreign Exchange Risk Member
Prospectus [Line Items]
Risk [Text Block]	Currency and Foreign Exchange Risk. When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars. The value of the foreign currency may increase or decrease against the value of the U.S. dollar, which may impact the value of the Fund’s portfolio holdings and your investment. Other countries may adopt economic policies and/or currency exchange controls that affect their currency valuations in a manner that is disadvantageous to U.S. investors and companies. Such practices may restrict or prohibit the Fund’s ability to repatriate both investment capital and income, or may impose fees for doing so, which could place the Fund’s assets at risk of total loss. Currency risks may be greater in emerging market and frontier market countries than in developed market countries.
Derivatives Risk Member
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk. The use of derivatives involves a variety of risks in addition to and greater than those associated with investing directly in securities. Derivatives instruments in which the Fund invests may not perform as anticipated by the Adviser, may not be closed out at a favorable time or price, or could increase the Fund’s volatility. Investment in derivatives may create investment leverage. When a derivative is used as a substitute for or alternative to a direct cash investment, the transaction may not provide a return that correlates precisely with that of the cash investment; or, when used for hedging purposes, derivatives may not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge. •Counterparty risk. The risk that the Fund will be subject to credit risk with respect to the counterparties to derivative contracts and other instruments entered into directly by the Fund. Other than to maintain its status as a regulated investment company for U.S. federal income tax purposes (described in the Statement of Additional Information under “Certain U.S. Federal Income Tax Information”), the Fund is not subject to any limit with respect to the number of transactions it can enter into with a single counterparty. To the extent that the Fund enters into multiple transactions with a single or a small set of counterparties, it will be subject to increased counterparty risk. •Futures contracts risk. The Fund’s use of futures contracts involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. In addition, while futures contracts are generally classified as liquid, under certain market conditions they may be classified as illiquid. As a result, the Fund may be unable to close out its futures contracts at a time which is advantageous. The successful use of futures depends upon a variety of factors, particularly the ability of the Adviser to predict movements of the underlying securities markets, which requires different skills than predicting changes in the prices of individual securities. There can be no assurance that any particular futures strategy adopted will succeed.
Derivatives Risk, Counterparty Risk Member

Risk [Text Block]	Counterparty risk. The risk that the Fund will be subject to credit risk with respect to the counterparties to derivative contracts and other instruments entered into directly by the Fund. Other than to maintain its status as a regulated investment company for U.S. federal income tax purposes (described in the Statement of Additional Information under “Certain U.S. Federal Income Tax Information”), the Fund is not subject to any limit with respect to the number of transactions it can enter into with a single counterparty.

As a result, the Fund may be unable to close out its futures contracts at a time which is advantageous.

There can be no assurance that any particular futures strategy adopted will succeed.
Options Risk Member
Prospectus [Line Items]
Risk [Text Block]	Options Risk. Options transactions involve special risks that may make it difficult or impossible to close a position when the Fund desires. A fund that purchases options, which are a type of derivative, is subject to the risk that gains, if any, realized on the position, will be less than the amount paid as premiums to the writer of the option. A fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments. A fund that writes covered call options gives up the opportunity to profit from any price increase in the underlying security above the option exercise price while the option is in effect.
Leverage Risk Member
Prospectus [Line Items]
Risk [Text Block]	Leverage Risk. Some transactions may give rise to a form of economic leverage and may expose the Fund to greater risk and increase its costs. Leverage can magnify the Fund’s gains and losses, and therefore increase its volatility.
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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
Large Capitalization Risk Member
Prospectus [Line Items]
Risk [Text Block]	Large Capitalization Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies.
Mid-Capitalization Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Mid-Capitalization Companies Risk. The Fund may invest in the securities of medium capitalization (“mid-cap”) companies. As a result, the Fund may be more volatile than funds that invest in larger, more established companies. The securities of mid-cap 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. Mid-cap companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.
Other Investment Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Other Investment Companies Risk. The risk of owning other investment companies, including ETFs, generally reflects the risks of owning underlying investments the other investment company holds. When the Fund invests in investment company securities, shareholders of the Fund bear indirectly their proportionate share of their fees and expenses, as well as their share of the Fund’s fees and expenses. 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.
Depositary Receipt Risk Member
Prospectus [Line Items]
Risk [Text Block]	Depositary Receipt Risk. ADRs, GDRs, and IDRs are certificates evidencing ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. However, they continue to be subject to many of the risks associated with investing directly in foreign securities. These risks include the social, political and economic risks of the underlying issuer’s country, as well as in the case of depositary receipts traded on non-U.S. markets, exchange risk. ADRs may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depository may establish an unsponsored facility without participation by the issuer of the depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs. As a result, there may not be a correlation between such information and the market values of unsponsored ADRs.
Debt Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	Debt Securities Risk. Increases in interest rates typically lower the value of debt securities held by the Fund. Investments in debt securities include credit risk. There is also the risk that a bond issuer may “call,” or repay its high yielding bonds before their maturity dates. Debt securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain debt securities may make it more difficult to sell or buy a security at a favorable price or time.
Credit Risk 1 Member
Prospectus [Line Items]
Risk [Text Block]	Credit Risk. An issuer of debt securities may not make timely payments of principal and interest and may default entirely in its obligations. A decrease in the issuer’s credit rating may lower the value of debt securities.
Interest Rate Risk 1 Member
Prospectus [Line Items]
Risk [Text Block]	Interest Rate Risk. Securities could lose value because of interest rate changes. For example, bonds tend to decrease in value if interest rates rise. Fixed-income securities with longer maturities sometimes offer higher yields, but are subject to greater price shifts as a result of interest rate changes than fixed-income securities with shorter maturities.
U.S. Government Obligations Risk Member
Prospectus [Line Items]
Risk [Text Block]	U.S. Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.
Cash Or Cash Equivalents Risk Member
Prospectus [Line Items]
Risk [Text Block]	Cash or Cash Equivalents Risk. At any time, the Fund may have all or substantially all of the Fund’s portfolio invested in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. In addition, holding cash or cash equivalents may cause the Fund to risk losing opportunities to participate in market appreciation, and may cause the Fund to experience potentially lower returns than the Fund’s benchmark or other funds that remain fully invested. In rising markets, holding cash or cash equivalents will negatively affect the Fund’s performance relative to its benchmark.
Market Events Risk Member
Prospectus [Line Items]
Risk [Text Block]	Market Events Risk. One or more markets in which the Fund invests may go down in value, including the possibility that the markets will go down sharply and unpredictably. This may be due to numerous factors, including changes in interest rates, the outlook for corporate profits, the health of the national and world economies, national and world social and political (including geopolitical) events, governmental actions, tariff and trade disruptions, and the fluctuation of other stock markets around the world.
High Portfolio Turnover Risk Member
Prospectus [Line Items]
Risk [Text Block]	High Portfolio Turnover Risk. A high portfolio turnover rate has the potential to result in the realization and distribution to shareholders of higher capital gains, which may subject you to a higher tax liability. High portfolio turnover also necessarily results in greater transaction costs which may reduce Fund performance.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	In addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	As with any fund, there are risks to investing. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
Risk Nondiversified Status [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a lesser number of issuers than if it was 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 lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Investment Risks - Myriad Dynamic Asset Allocation ETF

Sep. 25, 2025

ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks:

•Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has only a limited number of institutional investors (known as “Authorized Participants” or “APs”) that are authorized to purchase and redeem shares directly from the Fund. 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 the Fund’s net asset value (“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. This may lead to the widening of bid/ask spreads quoted throughout the day.

•Costs of Buying or Selling Shares. 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 may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments. This may lead to the widening of bid/ask spreads quoted throughout the day.

•Shares 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. Although it is expected that the market price of shares of the Fund 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. This may lead to the widening of bid/ask spreads quoted throughout the day. Because securities held by the Fund 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 of the Fund are listed for trading on the NYSE Arca (the “Exchange”), there can be no assurance that an active trading market for shares will develop or be maintained or that shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for shares of the Fund may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Fund’s shares, in turn, can lead to differences between the market price of the Fund’s shares and the underlying value of those shares. In addition, trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. This may lead to the widening of bid/ask spreads quoted throughout the day.

•Early Close/Trading Halt. An exchange or market may close early or issue trading halts on specific securities or financial instruments. The ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which the Fund’s shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. This may lead to the widening of bid/ask spreads quoted throughout the day.

•Listing Standards Risk. The Fund is required to comply with listing requirements adopted by the listing exchange. Non-compliance with such requirements may result in the Fund's shares being delisted by the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders.
