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 Fund 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. Because the Fund has not commenced operations as of the date of this prospectus, the portfolio turnover rate for the last fiscal year is not available. In the future, the portfolio turnover rate for the most recent fiscal year will be provided here.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a “fund of funds” which means that the Fund primarily invests in other exchange-traded funds (“ETFs”), including inverse ETFs. Inverse ETFs are designed to produce daily returns, before the effect of fees and expenses, that are the opposite of the daily returns of a reference index. Inverse ETFs are used by the Fund during persistently unfavorable market conditions. The Fund seeks to achieve its objective by using a rules-based models-driven approach to invest across a diversified universe of ETFs within eight sub-strategies (described below). The Fund’s investment advisor has delegated execution of the Fund’s strategy to Tuttle Tactical Management, LLC (the “Sub-Advisor”). The Sub-Advisor allocates the Fund’s portfolio, in part, using as an input to its decision making process, the research and models of Drawbridge Strategies, LLC (a financial consulting and index creation firm).

Each of the eight investment models represents up to 12.5% of the total Fund’s overall portfolio. The underlying investment models, as identified by asset class or sub-strategy are:

• U.S. Style Rotation - The U.S. Style Rotation model chooses the top performing investment style ETFs within the US stock market. Styles include large capitalization, medium or mid capitalization, and small capitalization companies along with growth, value, or core.

• U.S. Sector Rotation - The U.S. Sector Rotation model chooses the top performing sectors ETFs within the U.S. markets.

• Emerging Markets Rotation - The Emerging Markets Rotation model chooses the top performing country-specific and/or broad-based market ETFs within the MSCI Emerging Markets Index.

• Developed Countries Rotation - The Developed Countries Rotation model chooses the top performing country-specific and/or broad-based market ETFs within the MSCI EAFE Index.

• Credit & High Yield Tactical Rotation - The Credit & High Yield Tactical Rotation model chooses the top performing ETFs invested in treasury inflation protected securities (“TIPS”), short-term treasuries, intermediate corporate bonds, and high yield bonds.

• Real Estate ETF Rotation - The Real Estate ETF Rotation model chooses the top performing ETFs from a basket of ETFs that invest in both US and international real estate companies, including real estate investment trusts (“REITs”).

• Commodities ETF Rotation - The Commodities ETF Rotation model chooses the top performing ETFs invested in either precious metals, metals, energy, or agriculture, or a broad-based commodities index.

• Defensive ETF Rotation - The Defensive ETF Rotation model seeks to provide growth by choosing investments that historically perform better in periods of market stress. It chooses the top performing ETFs from short-term or long-term treasuries, gold, international and emerging markets bonds, energy sector, utilities sector, or consumer staples sector.

Each model may also direct for investment to cash and short and intermediate term investment grade fixed income securities, including treasury and corporate bond ETFs. The Fund may hold significant cash or fixed income positions during unfavorable market conditions and may be fully invested when favorable conditions warrant. Although not anticipated, in some market conditions, it is possible that cash and fixed income positions can be the highest mathematical ranking within each model. Consequently, one or more model strategies could select being fully invested in cash or fixed income. During persistently unfavorable market conditions, the U.S. Style Rotation, U.S. Sector Rotation, Emerging Markets Rotation, and Developed Countries Rotation strategies may use inverse ETFs. The strategy has an absolute return focus with the intent to maximize gains, while managing risk.

The ETFs held by the Fund may invest in domestic and foreign securities, equity securities of any market capitalization, and fixed-income securities of any maturity or duration. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. For example, if a bond has a duration of 5 years, a 1% rise in rates would result in a 5% decline in price. The Fund does not limit its investments to a particular credit quality and may invest in below investment grade securities (commonly referred to as “junk”) without limitation. Below investment grade securities are those rated below Baa3 by Moody’s Investor Services or equivalently by another nationally recognized statistical rating organization as well as non-rated securities.

The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors. The Fund may engage in frequent trading of its portfolio securities.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any ETF, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return and the value of the Fund and your investment. These risks affect the Fund directly as well as through the ETFs in which it invests.

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting.

Commodities Risk. Investing in the commodities markets (directly or indirectly) may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

Consumer Staples Sector Risk. The consumer staples sector may be affected by the regulation of various product components and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Credit Risk. There is a risk that issuers will not make payments on fixed income securities held by the Fund, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Fund may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

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.

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Emerging market economies may be based on only a few industries and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid.

Energy Sector Risk. Energy related entities are subject to supply and demand fluctuations in the markets they serve which will be impacted by a wide range of factors, including fluctuating commodity prices, weather, increased conservation or use of alternative fuel sources, increased governmental or environmental regulation, depletion, rising interest rates, declines in domestic or foreign production, accidents or catastrophic events, and economic conditions, among others. The financial performance of energy related securities may be adversely affected if a company is unable to cost-effectively acquire additional energy reserves. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of energy related securities.

Equity Securities Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. Equity securities may experience sudden, unpredictable drops in value or long periods of decline in value.

ETF Structure Risks: The Fund is structured as an ETF and as a result is subject to the special risks, including:

○ Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

○ Trading Issues. 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. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s 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 Fund’s shares.

○ 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. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

▪ 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 Fund shares and the Fund’s net asset value.

▪ The market price for the Fund’s shares may deviate from the Fund’s net asset value, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Fund shares than the Fund’s net asset value, which is reflected in the bid and ask price for Fund 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 Fund’s shares is open, there may be changes from the last quote of the closed market and the quote from the Fund’s trading day, which could lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

▪ In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s net asset value.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Recently, interest rates have been historically low and interest rate risk may be heightened. Other risk factors include credit risk (the debtor may default). Lowered credit ratings may cause a drop in a fixed income security’s price and are associated with greater risk of default on interest and principal payments. Certain fixed income securities may be paid off early. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income. If interest rates rise, repayments of principal on certain fixed income securities may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result, which reduces the Fund’s ability to reinvest at higher rates.

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid han investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries.

Gold Risk. The price of gold may be volatile and gold related ETFs may be highly sensitive to the price of gold. The price of gold bullion can be significantly affected by international monetary and political developments such as currency devaluation or revaluation, central bank movements, economic and social conditions within a country, transactional or trade imbalances, or trade or currency restrictions between countries. Physical gold bullion has sales commission, storage, insurance and auditing expenses.

Inflation-Indexed Bond Risk. Inflation-indexed bonds, such as TIPS, are fixed income securities whose principal values are periodically adjusted according to a measure of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds.

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities.

Inverse ETF Risk. 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.

Issuer Risk. The performance of the Fund depends on the performance of the issuers of the individual securities in which the Fund invests. Poor performance by any issuer may cause the value of its securities, and the value of the Fund’s Shares, to decline.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present a significant risk for loss of principal and interest. These bonds offer the potential for higher return, but also involve greater risk than bonds of higher quality, including an increased possibility that the bond’s issuer, obligor or guarantor may not be able to make its payments of interest and principal (credit quality risk). If that happens, the value of the bond may decrease, and the Fund’s share price may decrease and its income distribution may be reduced. These securities are considered speculative in nature. An economic downturn or period of rising interest rates (interest rate risk) could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds (liquidity risk). Such securities may also include “Rule 144A” securities, which are subject to resale restrictions. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Large Capitalization Stock Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Limited History of Operations. The Fund has a limited history of operations for investors to evaluate. If the Fund is unable to achieve an economic size, expenses will be higher than expected and the Fund might close, which could produce adverse tax consequences for shareholders.

Management Risk. The investment advisor’s assessment of the Sub-Advisor’s investment acumen may prove incorrect. The Sub-Advisor’s reliance on its models-driven strategy and related judgments about the value and potential appreciation securities in which the Fund invests may prove to be incorrect. The Sub-Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

Market Risk. Overall stock and bond market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels and political events affect the securities markets.

Mid/Small-Cap Stock Risk. Because the smaller companies in which the Fund may invest may have unproven track records, a limited product or service base and limited access to capital, they may be more likely to fail than larger companies.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models are usually constructed based on data supplied by third parties, the success of the Sub-Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Non-Diversification Risk. To the extent that the Fund holds securities of a smaller number of issuers or invests a larger percentage of its assets in a single issuer than a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers and to economic, political, market or regulatory events affecting any one of those issuers.

Real Estate/REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate. The real estate industry is particularly sensitive to economic downturns. The value of REITs and other real estate-related investments is sensitive to changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, overbuilding, extended vacancies of properties and the issuer’s management skills. In the event of a default by an underlying tenant or borrower, a REIT could experience delays in enforcing its rights as a lessor or mortgagee and may incur substantial costs associated with protecting its investments. In addition, the value of a REIT can depend on the structure of and cash flow generated by the REIT. Also, REITs may have limited financial resources, may trade less frequently and in limited volume and may be more volatile than other securities.

Sector Risk. If the Fund focuses its investments within a particular Sector, it is subject to increased risk. Performance will generally depend on the performance of the Sector, which may differ in direction and degree from that of the overall U.S. stock markets. In addition, financial, economic, business and political developments affecting the Sector may have a greater effect on the Fund than they would if the Fund did not focus on that Sector.

Turnover Risk. The Fund may have a high turnover of the securities held in its portfolio. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

Underlying Fund Risk. Other investment companies, that is ETFs (“Underlying Funds”) in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other mutual funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks, but the Adviser expects the principal investments risks of such Underlying Funds will be similar to the risks of investing in the Fund. Certain additional risks of investing in ETFs are described below:

○ Net Asset Value and Market Price Risk: The market value of ETF shares may differ from their net asset value. This difference in price may be due to the fact that the supply and demand in the market for fund shares at any point in time is not always identical to the supply and demand in the market for the underlying basket of securities. Accordingly, there may be times when shares trade at a premium or discount to net asset value.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits.. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

To the extent that the Fund holds securities of a smaller number of issuers or invests a larger percentage of its assets in a single issuer than a diversified portfolio, the value of the Fund, as compared to the value of a diversified portfolio, will generally be more volatile and more sensitive to the performance of any one of those issuers and to economic, political, market or regulatory events affecting any one of those issuers.
