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 Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 2,155% of the average value of its portfolio.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees The Total Annual Fund Operating Expenses After Fee Waiver does not correlate to the ratios of expenses to average net assets included in the Financial Highlights section of the Fund’s Statutory Prospectus, which reflects the operating expenses of the Fund and does not include acquired fund fees and expenses (“AFFE”).
Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you compare the costs of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (taking into account the expense limitation for one year). You may be required to pay brokerage commissions on your purchases and sales of Institutional Class shares of the Fund from a financial intermediary, which are not reflected in this table.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
To achieve the Fund’s investment objective, the Adviser invests the Fund’s assets primarily in shares of a diversified portfolio of exchange-traded funds (“ETFs”) that track various indices or multiples thereof, sometimes referred to in this Prospectus as “Underlying ETFs.” These indices may track the performance of the equity and/or fixed income markets, in general, or the performance of specific sectors (e.g., a large grouping of companies operating within the market that share similar characteristics) or market segments (e.g., large, medium, or small capitalization domestic and/or foreign companies, including those in emerging markets). The Fund may also invest in ETFs that seek to achieve returns on a daily or monthly basis that are a multiple of the returns of the target index through the utilization of leveraging techniques. The Fund may also invest in exchange-traded notes (“ETNs”). ETNs are debt obligations typically issued by investment banks that are traded on exchanges and whose returns are linked to the performance of market indices.
The Adviser intends to invest in Underlying ETFs that correspond to one or more asset classes. The Underlying ETFs may hold equity securities (e.g., common and preferred stock) of small, medium and large capitalization domestic or foreign companies, which may include companies located in emerging markets. Underlying ETFs may also hold fixed income securities such as government and corporate bonds issued by a variety of domestic and foreign entities. These fixed income securities may have varying maturities (e.g., short-term, intermediate or long-term) and credit qualities (e.g., high quality, investment grade or below investment grade, also known as “junk bonds”). The Fund, however, reserves the right to invest all of its assets in any one asset class depending upon market conditions. When investing in Underlying ETFs that track multiples of various indices, the Fund limits its investments in such Underlying ETFs to 25% of total assets at the time of purchase. Additionally, the Fund may utilize leverage as part of the portfolio management process through investing in Underlying ETFs that utilize leveraging techniques. The Fund may invest in underlying funds that utilize futures contracts, options on futures contracts, securities and indices, forward contracts, swap agreements and similar instruments. Additionally, the Fund may utilize leverage (i.e., borrow against a line of credit) as part of the portfolio management process.
The Adviser’s proprietary investment approach is designed to target various segments of the investable landscape by allocating primarily between equities and bonds depending on the potential for near-term stock market volatility as signaled through inter-market trends and relative prices. When indicators suggest equity volatility is likely to fall, stocks tend to outperform bonds, and when indicators suggest equity volatility is likely to rise, bonds tend to outperform stocks. The Adviser’s approach allocates into equities, or bonds based on these historical observations and attempts to identify specific areas within each asset class which have the near-term potential to outperform. The Adviser uses quantitative signals that help to identify the ETFs in which to position the Fund’s portfolio. Using ETFs allows for liquid and timely exposure to desired markets and provides the Fund with the ability to reposition holdings in dynamic investing environments. Quantitative signals include relative momentum as measured by price movement, strength of the opportunity set defined as equities and bonds, and the firm’s proprietary combination of historically proven leading indicators of stock market volatility, as discovered through internal research.
The Fund can make aggressive moves into or out of any particular asset class on a short-term basis and, as a result, the Adviser expects that the Fund will have a high portfolio turnover rate. The Adviser anticipates that the Fund’s portfolio turnover could exceed 2,000% on an annual basis, depending on market conditions. Because the Fund pays transaction costs, such as commissions, when it buys and sells ETFs, a higher portfolio turnover rate may result in higher transaction costs and, when Fund shares are held in a taxable account, in higher taxes. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example above, affect the Fund’s performance.
The use of leverage may magnify the effect of any decrease or increase in the value of the Fund's portfolio securities. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

ATAC Rotation Fund | Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other governmental agency.
ATAC Rotation Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
General Market Risk. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
ATAC Rotation Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Management Risk. The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if the Adviser cannot successfully implement the Fund’s investment strategies.
ATAC Rotation Fund | Asset Allocation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Asset Allocation Risk. The Fund’s allocation among Underlying ETFs with various asset classes and investments may not produce the desired results.
ATAC Rotation Fund | Limited Holdings Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Limited Holdings Risk. The Fund may invest in a single or small number of Underlying ETFs, which may result in increased volatility.
ATAC Rotation Fund | Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) has the potential to result in the realization by the Fund, and the distribution to shareholders, of a greater amount of capital gains than if the Fund had a low portfolio turnover rate. The Fund anticipates that its portfolio turnover could exceed 2,000% on an annual basis depending on market conditions. This may mean that you would likely have a higher tax liability. Distributions to shareholders of short-term capital gains are taxed as ordinary income under federal tax laws. When purchasing securities for the Fund through a broker, high portfolio turnover generally involves correspondingly greater brokerage commission expenses, which must be borne directly by the Fund and indirectly by the Fund’s shareholders.
ATAC Rotation Fund | ETF Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ETF Risk. The market price of the shares of an Underlying ETF will fluctuate based on changes in the net asset value as well as changes in the supply and demand of its shares in the secondary market. It is also possible that an active secondary market for an Underlying ETF’s shares may not develop, and market trading in the shares of the Underlying ETF may be halted under certain circumstances.
ATAC Rotation Fund | Underlying ETFs Expense Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Underlying ETFs Expense Risk. The Underlying ETFs have management and other expenses. The Fund will bear its pro rata portion of these expenses and therefore the Fund’s expenses may be higher than if it invested directly in securities.
ATAC Rotation Fund | Bond Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Bond Market Risk. These risks apply to the extent the Underlying ETFs hold fixed-income securities. Interest rate risk is the risk that interest rates may go up resulting in a decrease in the value of the securities held by the Underlying ETFs. Prepayment risk is the risk that the issuer of a fixed-income security can repay principal faster than expected prior to the security’s maturity. Extension risk is the risk that rising interest rates could cause prepayments of the obligations to decrease. Maturity risk is the risk that the longer a fixed-income security’s maturity, the lower its yield and the greater the risk of volatility. Credit risk is the risk that an issuer will not make timely payments of principal and interest. Changes in market conditions and government policies may lead to periods of heightened volatility and reduced liquidity in the fixed-income securities market, and could result in an increase in Fund redemptions. Interest rate changes and their impact on the Fund and its share price can be sudden and unpredictable.
ATAC Rotation Fund | Government-Sponsored Entities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Government-Sponsored Entities Risk. The Fund invests in Underlying ETFs that hold securities issued or guaranteed by government-sponsored entities. However, these securities may not be guaranteed or insured by the U.S. government and may only be supported by the credit of the issuing agency. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
ATAC Rotation Fund | High-Yield Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
High-Yield Securities Risk. The fixed-income securities held by Underlying ETFs that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on public perception of the issuer.
ATAC Rotation Fund | Large-Cap, Mid-Cap And Small-Cap Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Large-Cap, Mid-Cap and Small-Cap Companies Risk. An Underlying ETF’s investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.  Securities of mid-cap and small-cap companies may be more volatile and less liquid than the securities of large-cap companies.
ATAC Rotation Fund | Tracking Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Tracking Risk. Although an Underlying ETF may seek to match positively or negatively the returns of an index, the Underlying ETF’s return may not match or achieve a high degree of correlation with the return of its applicable index.
ATAC Rotation Fund | Compounding Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Compounding Risk. As a result of mathematical compounding and because Underlying ETFs that seek to achieve returns that are a multiple of the target index often have a single day investment objective to track the performance of an index or a multiple thereof, the performance of an Underlying ETF for periods greater than a single day is likely to be either greater than or less than the index performance, before accounting for the Underlying ETF’s fees and expenses. Compounding will cause longer term results to vary from the return of the index, particularly during periods of higher index volatility.
ATAC Rotation Fund | Aggressive Investment Technique Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Aggressive Investment Technique Risk. Some of the Underlying ETFs in which the Fund invests may use investment techniques considered to be aggressive, including using futures contracts, options on futures contracts, securities and indices, forward contracts, swap agreements and similar instruments. Because an Underlying ETF’s investment in financial instruments may involve a small investment relative to the amount of investment exposure assumed, it may result in losses exceeding the amounts invested.
ATAC Rotation Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk. Investments in securities issued by foreign issuers involve risks not generally associated with investments in the securities of U.S. companies, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and tax requirements and market practices, as well as fluctuations in foreign currencies. These risks are greater in emerging markets. There may be less information publicly available about foreign companies than about a U.S. company, and many foreign companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the United States. Unexpected political, regulatory and diplomatic events within the United States and abroad may affect investor and consumer confidence and may adversely impact global financial markets and the broader economy. Foreign conflicts have caused, and could continue to cause, significant market disruptions and volatility within specific markets and globally.
ATAC Rotation Fund | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Emerging Markets Risk. Emerging markets are markets of countries in the initial stages of industrialization and that generally have low per capita income. In addition to the risks of foreign securities in general, emerging markets are generally more volatile, have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries and securities markets that are substantially smaller, less liquid and more volatile with less government oversight than more developed countries.
ATAC Rotation Fund | Derivative Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Derivative Risk. Some Underlying ETFs may use derivative instruments which derive their value from the value of an underlying asset, currency or index. The value of derivatives may rise or fall more rapidly than other investments and it is possible to lose more than the initial amount invested.
ATAC Rotation Fund | Leverage Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Leverage Risk. Some Underlying ETFs may borrow money for leveraging. Interest expenses may exceed the income from the assets purchased with such borrowings. While the interest obligation resulting from borrowing will be fixed (although they may fluctuate with changing market rates of interest depending on the terms of the relevant agreement), the NAV per share of the Underlying ETF will tend to increase more when its portfolio securities increase in value and to decrease more when its portfolio assets decrease in value than would otherwise be the case if it did not borrow funds.
ATAC Rotation Fund | Short Sales Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Short Sales Risk. Underlying ETFs may engage in short sales which could cause an Underlying ETF’s investment performance to suffer if it is required to close out a short position earlier than it had intended.
ATAC Rotation Fund | Preferred Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Preferred Stock Risk. A preferred stock is a blend of the characteristics of a bond and common stock. It may offer a higher yield than common stock and has priority over common stock in equity ownership, but it does not have the seniority of a bond and, unlike common stock, its participation in the issuer’s growth may be limited. Although the dividend on a preferred stock may be set at a fixed annual rate, in some circumstances it may be changed or passed by the issuer. Preferred stock generally does not confer voting rights.
ATAC Rotation Fund | ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ETN Risk. The value of an ETN may be influenced by its time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities’ markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index. In addition, ETNs are unsecured debt of the issuer and would lose value if the issuer goes bankrupt.

[1] The Total Annual Fund Operating Expenses After Fee Waiver does not correlate to the ratios of expenses to average net assets included in the Financial Highlights section of the Fund’s Statutory Prospectus, which reflects the operating expenses of the Fund and does not include acquired fund fees and expenses (“AFFE”).
[2] Tidal Investments LLC (the “Adviser”) has contractually agreed to waive a portion or all of its management fees and reimburse Fund expenses, in order to ensure that Total Annual Fund Operating Expenses (excluding certain expenses such as taxes, leverage interest, interest expense, dividends paid on short sales, brokerage commissions, AFFE, or extraordinary expenses) do not exceed 1.74% of the average daily net assets of the Fund’s Investor Class shares and do not exceed 1.49% of the average daily net assets of the Fund’s Institutional Class shares. Fees waived and expenses paid by the Adviser may be recouped by the Adviser for a period of 36 months following the month during which such fee waiver and expense payment was made if such recoupment can be achieved without exceeding the expense limit in effect at the time the fee waiver and expense payment occurred and the expense limit in place at the time of recoupment. The Operating Expenses Limitation Agreement is indefinite, but cannot be terminated through at least December 29, 2025. Thereafter, the agreement may be terminated at any time upon 60 days’ written notice by the Trust’s Board of Trustees (the “Board”) or the Adviser, with the consent of the Board.
