Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.  For the fiscal year ended May 31, 2022, the Fund’s portfolio turnover rate was 29.36% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
As an actively managed exchange-traded fund (“ETF”), the Fund will not seek to replicate the performance of an index. The Advisor seeks to achieve the Fund’s investment objective of capital appreciation by investing in exchange-traded funds (“ETFs”) that are registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and not affiliated with the Fund (“Portfolio Funds”). In addition to its indirect investments, the Fund may also invest directly in put and call options on index ETFs, sector ETFs, individual equities, and cash and cash equivalents as part of its risk management strategy.
The Advisor splits the Fund’s portfolio into two segments: core and opportunistic. For the core segment of the Fund’s strategy, the Advisor may invest in ETFs that track the S&P 500 Index and utilize puts and calls for hedging the corresponding ETF. The investments of the Portfolio Funds will generally be comprised of equity securities included in the S&P 500 Index and principally consisting of common stock. The Advisor will balance the Fund’s Portfolio Funds around these core equity holdings.
The Advisor uses an investment model for analyzing market trends. The investment model includes factors such as price momentum, volatility, and comparative indicators relative to certain indices.  When the Advisor’s model indicates a negative market trend, the Fund may hedge the Fund’s portfolio by investing in ETFs that invest in treasury bonds, exchange traded notes (“ETNs”), and leverage and inverse ETFs. The leveraged ETFs hedge the Fund’s portfolio by offsetting equity allocations without need to sell the long equity positions. The Fund may hold significant cash or inverse ETF positions during unfavorable market conditions.
The opportunistic segment of the Fund’s portfolio consists of an allocation to large cap growth and/or large cap value  ETFs. The allocation is determined by the Advisor’s model, which considers relative historical performance between the S&P 500 Growth Index and the S&P 500 Value Index, and the momentum of the relative historical performance of the S&P 500 Growth Index and the S&P 500 Value Index to determine the relative value between U.S. large cap growth and U.S. large cap value securities. The S&P 500 Growth Index is a sub-set of the S&P 500 Index that includes growth stocks, which it measures using three factors: sales growth, the ratio of earnings change to price, and momentum. The S&P 500 Value Index is a sub-set of the S&P 500 Index that includes value stocks, which it measures using three factors: the ratios of book value, earnings, and sales to price.
The Fund will employ a risk management strategy intended to manage the volatility of the Fund’s returns and manage the overall risk of investing in the Fund. The risk management strategy monitors technical metrics on equity indices that may identify periods where there is potential for higher equity market risk. These technical metrics use mathematically based tools to identify positive or negative trends in equity indices, so, when the technical metrics identify a negative trend, there may be a potential for higher equity market risk.  When periods of declining equity markets are more likely, the risk management strategy will reduce equity exposure. When employing this risk management strategy, the Fund may allocate a significant percentage of its assets to cash and cash equivalents. When employing the risk management strategy, in addition to cash and cash equivalents, the Fund may utilize a hedge overlay for downside protection, which will include put and call options and ETFs that have exposure to changes in volatility or offer inverse performance to equity markets (inverse ETFs).  The hedge overlay will be used when the Advisor believes there is the potential for higher risk of loss in equity markets.
The Portfolio Funds in which the Fund invests will have an investment objective similar to the Fund’s or will otherwise track particular market sectors. Although the Fund principally invests in Portfolio Funds with no sales related expenses or very low sales related expenses, the Fund is not precluded from investing in Portfolio Funds with sales-related expenses, redemption fees, and/or service fees. The Fund may have a relatively high level of portfolio turnover compared to other mutual funds, which may affect the Fund’s performance due to higher transactions costs and higher taxes. Portfolio turnover will not be a limiting factor in making investment decisions.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the average annual total returns compared to that of a broad-based securities market index. The Fund acquired all of the assets and liabilities of the Adaptive Tactical Rotation Fund, a series of Starboard Investment Trust (the “Trust”), (the “Predecessor Fund”) in a tax-free reorganization on November 5, 2021. In connection with this acquisition, shares of the Predecessor Fund’s Institutional Class shares, Class A shares, and Class C shares were exchanged for Shares. The Predecessor Fund had an investment objective and strategies that were, in all material respects, the same as those of the Fund, and was managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Fund. The performance information set forth below reflects the historical performance of the Predecessor Fund’s Institutional Class shares. Prior to July 31, 2015, the Fund had a different investment advisor. The Fund changed its investment strategy effective October 1, 2022. The Fund changed its investment strategy effective June 9, 2023. The performance information set forth below does not reflect the Fund’s current strategy or ETF structure.

Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock The loss of your money is a principal risk of investing in the Fund.
RH Tactical Rotation ETF | Common Stock Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Common Stock Risk.  Investments by the Portfolio Funds in shares of common stock may fluctuate in value response to many factors, including the activities of the individual issuers whose securities the Portfolio Fund owns, general market and economic conditions, interest rates, and specific industry changes. Such price fluctuations subject the Portfolio Fund to potential losses.  During temporary or extended bear markets, the value of common stocks will decline, which could also result in losses for the Portfolio Fund.
RH Tactical Rotation ETF | Control of Portfolio Funds Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Control of Portfolio Funds Risk.  The Portfolio Funds each have their own unique investment objective, strategies, and risks.  There is no guarantee that the Portfolio Funds will achieve their investment objectives and the Fund has exposure to the investment risks of the Portfolio Funds in direct proportion to the allocation of assets among the funds.  The investment policies of the Portfolio Funds may differ from the Fund’s policies. Although the Fund and the Advisor will evaluate regularly each Portfolio Fund to determine whether its investment program is consistent with the Fund’s investment objective, the Advisor will not have any control over the investments made by a Portfolio Fund.  The investment advisor to each Portfolio Fund may change aspects of its investment strategies at any time.  The Advisor will not have the ability to control or otherwise influence the composition of the investment portfolio of a Portfolio Fund.
RH Tactical Rotation ETF | Equity Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Equity Securities Risk.  Investments by the Portfolio Funds in equity securities may fluctuate in value response to many factors, including the activities of the individual issuers whose securities the Portfolio Fund owns, general market and economic conditions, interest rates, and specific industry changes. Such price fluctuations subject the Fund to potential losses. During temporary or extended bear markets, the value of equity securities will decline, which could also result in losses for the Fund.
RH Tactical Rotation ETF | Leveraged and Inverse ETF Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Leveraged and Inverse ETF Risk. Investing in leveraged ETFs will amplify the Fund’s gains and losses. Most leveraged ETFs “reset” daily. Due to the effect of compounding, their performance over longer periods of time can differ significantly from the performance of their underlying index or benchmark during the same period of time. Investments in inverse ETFs will prevent the Fund from participating in market-wide or sector-wide gains and may not prove to be an effective hedge. During periods of increased volatility, inverse ETFs may not perform in the manner they are designed.
RH Tactical Rotation ETF | ETF Investing Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock ETF Investing Risk.  The Fund’s investment in ETFs may subject the Fund to additional risks than if the Fund would have invested directly in the ETF’s underlying securities. These risks include the possibility that an ETF may experience a lack of liquidity that can result in greater volatility than its underlying securities, an ETF may trade at a premium or discount to its net asset value, or an ETF may not replicate exactly the performance of the benchmark index it seeks to track. In addition, investing in an ETF may also be costlier than if the Fund had owned the underlying securities directly. The Fund and, indirectly, shareholders of the Fund, bear a proportionate share of the ETF’s expenses, which include management and advisory fees and other expenses. In addition, the Fund will pay brokerage commissions in connection with the purchase and sale of ETFs in the Fund’s portfolio. Although the Fund and the Advisor will evaluate regularly each Portfolio Fund to determine whether its investment program is consistent with the Fund’s investment objective, the Advisor will not have any control over the investments made by a Portfolio Fund.  The investment advisor to each Portfolio Fund may change aspects of its investment strategies at any time.  The Advisor will not have the ability to control or otherwise influence the composition of the investment portfolio of a Portfolio Fund.
RH Tactical Rotation ETF | Fund Investing Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Fund Investing Risk.  Investments in other investment companies subject the Fund to additional operating and management fees and expenses. Investors in the Fund will indirectly bear fees and expenses charged by the funds in which the Fund invests, in addition to the Fund’s direct fees and expenses.  The Fund’s performance depends in part upon the performance of the investment advisor to each Portfolio Fund, the strategies and instruments used by the Portfolio Funds, and the Advisor's ability to select Portfolio Funds and effectively allocate fund assets among them.
RH Tactical Rotation ETF | ETN Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock ETN Risk. Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that comprise the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risk.
RH Tactical Rotation ETF | Investment Advisor Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Investment Advisor Risk.  The Advisor’s ability to choose suitable investments has a significant impact on the ability of the Fund to achieve its investment objectives.
RH Tactical Rotation ETF | Management Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s portfolio securities, the Advisor will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.
RH Tactical Rotation ETF | Large-Cap Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Large-Cap Securities Risk.  Stocks of large companies as a group can fall out of favor with the market, causing the Fund to underperform investments that have a greater focus on mid-cap or small-cap stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
RH Tactical Rotation ETF | Risks from Selling or Writing Options [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Risks from Selling or Writing Options.  Writing option contracts can result in losses that exceed the Fund’s initial investment and may lead to additional turnover and higher tax liability.  The risk involved in writing a call option is that there could be an increase in the market value of the security. If this occurred, the option could be exercised and the underlying security would then be sold by the Fund at a lower price than its current market value or in the case of cash settled options, the Fund would be required to purchase the option at a price that is higher than the original sales price for such option. Similarly, while writing call options can reduce the risk of owning stocks, such a strategy limits the opportunity of the Fund to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. The risk involved in writing a put option is that there could be a decrease in the market value of the underlying security. If this occurred, the option could be exercised and the underlying security would then be sold to the Fund at a higher price than its current market value or in the case of cash settled options, the Fund would be required to purchase the option at a price that is higher than the original sales price for such option.
RH Tactical Rotation ETF | Risks from Purchasing Options [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Risks from Purchasing Options.  If a call or put option purchased by the Fund is not sold when it has remaining value and if the market price of the underlying security, in the case of a call, remains less than or equal to the exercise price, or, in the case of a put, remains equal to or greater than the exercise price, the Fund will lose its entire investment in the option.  Since many factors influence the value of an option, including the price of the underlying security, the exercise price, the time to expiration, the interest rate, and the dividend rate of the underlying security, the Advisor’s success in implementing the Fund’s strategy may depend on an ability to predict movements in the prices of individual securities, fluctuations in markets, and movements in interest rates.  There is no assurance that a liquid market will exist when the Fund seeks to close out an option position.  Where a position in a purchased option is used as a hedge against price movements in a related position, the price of the option may move more or less than the price of the related position.
RH Tactical Rotation ETF | Counterparty Credit Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Counterparty Credit Risk. The stability and liquidity of many derivative transactions depends in large part on the creditworthiness of the parties to the transactions. If a counterparty to such a transaction defaults, exercising contractual rights may involve delays or costs for the Fund. Furthermore, there is a risk that a counterparty could become the subject of insolvency proceedings, and that the recovery of securities and other assets from such counterparty will be delayed or be of a value less than the value of the securities or assets originally entrusted to such counterparty.
RH Tactical Rotation ETF | Managed Volatility Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Managed Volatility Risk. Techniques used by the Advisor to manage the volatility of the Fund’s investments carry the risks that such techniques may not protect against market declines. The techniques may also limit the Fund’s participation in market gains, particularly during periods where market values are increasing but market volatility is high. Further, such techniques may increase portfolio transaction costs, which could result in losses or reduced gains. They also may not be successful as the techniques are subject to the Advisor’s ability to correctly analyze and implement the volatility management techniques in a timely manner.
RH Tactical Rotation ETF | Market Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Market Risk.  Market risk refers to the possibility that the value of securities held by the Fund may decline due to daily fluctuations in the market. Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general.  The price of a security may even be affected by factors unrelated to the value or condition of its issuer, including changes in interest rates, economic and political conditions, and general market conditions.  The Fund’s performance per share will change daily in response to such factors.
RH Tactical Rotation ETF | Portfolio Turnover Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk.  The Advisor will sell Portfolio Funds and other securities when it is in the best interest of the Fund and its shareholders to do so without regard to the length of time they have been held. As portfolio turnover may involve paying brokerage commissions and other transaction costs, there could be additional expenses for the Fund.  High rates of portfolio turnover may also result in the realization of short-term capital gains and losses. Any distributions resulting from such gains will be considered ordinary income for federal income tax purposes.
RH Tactical Rotation ETF | Cash and Cash Equivalents Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Cash and Cash Equivalents Risk. At any time, the Fund may have significant investments 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.
RH Tactical Rotation ETF | Quantitative Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Quantitative Risk.  Securities or other investments selected using quantitative methods may perform differently from the market as a whole. There can be no assurance that these methodologies will enable the Fund to achieve its objective.
RH Tactical Rotation ETF | Small-Cap and Mid-Cap Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Small-Cap and Mid-Cap Securities Risk.  The Portfolio Funds may invest in securities of small-cap and mid-cap companies, which involves greater volatility than investing in larger and more established companies.  Small-cap and mid-cap companies can be subject to more abrupt or erratic share price changes than larger, more established companies.  Securities of these types of companies have limited market liquidity, and their prices may be more volatile.  You should expect that the value of the Portfolio Fund’s shares will be more volatile than a fund that invests exclusively in large-capitalization companies.
RH Tactical Rotation ETF | Convertible Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Convertible Securities Risk.  Convertible securities are fixed income securities that the Fund or a Portfolio Fund has the option to exchange for equity securities at a specified conversion price.  The option allows the Fund or a Portfolio Fund to realize additional returns if the market price of the equity securities exceeds the conversion price.  Convertible securities have lower yields than comparable fixed income securities and may provide lower returns than non-convertible fixed income securities or equity securities depending upon changes in the price of the underlying equity securities.
RH Tactical Rotation ETF | Preferred Equity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Preferred Equity Risk.  Preferred equity’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred equity may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred equity tends to vary more with fluctuations in the underlying common equity and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred equity may suffer a loss of value if dividends are not paid and have limited voting rights.
RH Tactical Rotation ETF | Cybersecurity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Cybersecurity Risk. As part of its business, the Advisor processes, stores, and transmits large amounts of electronic information, including information relating to the transactions of the Fund. The Advisor and the Fund are therefore susceptible to cybersecurity risk. Cybersecurity failures or breaches of the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, and/or reputational damage. The Fund and its shareholders could be negatively impacted as a result.
RH Tactical Rotation ETF | Pandemic Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Pandemic Risk. There is an ongoing global outbreak of COVID-19, which has spread to over 200 countries and territories, including the United States. The general uncertainty surrounding the dangers and impact of COVID-19 has created significant disruption in global supply chains and economic activity, increasing rates of unemployment and adversely impacting many industries. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The outbreak of the COVID-19 pandemic has, at times, had, and is expected to continue to pose a risk of having, a material adverse impact on the Fund’s market price, NAV and portfolio liquidity among other factors. These impacts will likely continue to some extent as the outbreak persists and potentially even longer. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions, and, as a result, present material uncertainty and risk with respect to the Fund and the performance of its investments. COVID-19 and the current financial, economic and capital markets environment, and future developments in these and other areas present uncertainty and risk with respect to the Fund’s performance, portfolio liquidity, ability to pay distributions and make share repurchases.
RH Tactical Rotation ETF | Authorized Participant Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Authorized Participant Risk. Only an authorized participant (“Authorized Participant” or “APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). Authorized Participant concentration risk may be heightened for exchange-traded funds (ETFs), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
RH Tactical Rotation ETF | ETF Structure Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to the special risks, including:
RH Tactical Rotation ETF | Not Individually Redeemable [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
o
Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at net asset value (“NAV”) only in large blocks known as “Creation Units.”  You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.
RH Tactical Rotation ETF | Trading Issues [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
o
Trading Issues. An active trading market for the Shares may not be developed or maintained. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Shares. Any absence of an active trading market, in turn, lead to a heightened risk of a difference between the market price of the Shares and the value of the Shares, which would be reflected in a wider bid-ask spread.
RH Tactical Rotation ETF | Cash purchases [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
o
Cash purchases. To the extent Creation Units are purchased by APs in cash instead of in-kind, the Fund will incur certain costs such as brokerage expenses and taxable gains and losses. These costs could be imposed on the Fund and impact the NAV if not fully offset by transaction fees paid by the APs.
RH Tactical Rotation ETF | Market Price Variance Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
o
Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. A bid-ask spread is the difference between the price quoted in the market for an immediate sale (bid) and an immediate purchase (ask) of the ETF’s shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV, and the bid-ask spread could widen.
•
In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Shares and the NAV, and the bid-ask spread could widen.
•
To the extent authorized participants exit the business or are unable to process creations or redemptions and no other AP can step in to do so, there may be a significantly reduced trading market in the Shares, which can lead to differences between the market value of Shares and the NAV, and the bid-ask spread could widen.
•
The market price for the Shares may deviate from the NAV, particularly during times of market stress, with the result that investors may pay significantly more or receive significantly less for Shares than the NAV, which is reflected in the bid and ask price for Shares or in the closing price.
•
When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s domestic trading day, which could lead to differences between the market value of the Shares and the NAV, and the bid-ask spread could widen.
•
In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the NAV, and the bid-ask spread could widen.
RH Tactical Rotation ETF | Early Close/Trading Halt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may prevent the Fund from buying or selling 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 may incur substantial trading losses.

[1] “Acquired Fund” means any investment company in which the Fund invests or has invested during the previous fiscal year.  The “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” will not match the Fund’s gross and net expense ratios reported in the Financial Highlights from the Fund’s financial statements, which reflect the operating expenses of the Fund and do not include Acquired Fund Fees and Expenses.
[2] Cavalier Investments, LLC d/b/a Adaptive Investments, the investment advisor to the Fund (the “Advisor”), has entered into an expense limitation agreement with the Fund under which it has agreed to waive or reduce its fees and assume other expenses of the Fund, if necessary, in an amount that limits the Fund’s annual operating expenses (exclusive of: (i) any front-end or contingent deferred loads; (ii) brokerage fees and commissions, (iii) acquired fund fees and expenses; (iv) fees and expenses associated with investments in other collective investment vehicles or derivative instruments (including for example option and swap fees and expenses); (v) borrowing costs (such as interest and dividend expense on securities sold short); (vi) taxes; and (vii) extraordinary expenses, such as litigation expenses (which may include indemnification of Fund officers and Trustees and contractual indemnification of Fund service providers (other than the Advisor)) to not more than 1.25% of the Fund. Net annual operating expenses for the Fund may exceed these limits to the extent that it incurs expenses enumerated above as exclusions. The expense limitation agreement runs through September 30, 2023, and may be terminated by the Board at any time. The Advisor cannot recoup from the Fund any amounts paid by the Advisor under the expense limitation agreement.
