Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock To pursue its investment objective, the Fund invests, under normal market circumstances, at least 80% of
its net assets (plus any borrowings for investment purposes) in component securities of the Underlying
Index. The Underlying Index is sponsored and maintained by Abacus FCF Indexes LLC (the "Index
Provider"), an affiliate of Abacus FCF Advisors LLC, the Fund’s investment adviser (the “Adviser”). The
Underlying Index is a rules-based equity index designed to track the performance of U.S. publicly traded
companies with strong free cash flow return on invested capital (“FCF-ROIC”) and strong research and
development (“R&D”) investment, as identified by the Index Provider through extensive historical
research. The Fund intends to maintain a portfolio of securities that generally replicates the holdings of
the Underlying Index.
To be eligible for inclusion in the Underlying Index, an equity security must meet the following
requirements (“Eligible Securities”): (i) be a U.S. listed common stock; (ii) have a minimum total market
capitalization larger than the 97th percentile of the cumulative market capitalization of all Eligible
Securities; (iii) have an average monthly trading volume of greater than $75 million over the last six
months; and (iv) have been issued by a company that has reported over the past 12 months certain
characteristics of its expenses, including free cash flow and positive R&D expense.
The Underlying Index utilizes the Adviser’s proprietary Abacus FCF Leaders Model (the “Model”) to
evaluate Eligible Securities and scores them based on FCF-ROIC. The Model assesses a company’s FCF-
ROIC by analyzing factors such as capital expenditure, accruals, cash flow margins, and asset turnover.
The FCF-ROIC score is then combined with the degree of R&D investment to derive the FCF Innovation
Leaders Score (the “Score”), which helps identify companies with strong and sustainable profitability and
innovation.
A target weighting is then assigned to each Eligible Security based on its Score, with adjustments for
company-specific risk using a proprietary factor derived from the historical volatility of each Eligible
Security’s stock price over the preceding 12-month period. The resulting risk-adjusted score is used to
calculate active weights for each security, which are combined with their free-float market capitalization.
The Underlying Index includes those remaining Eligible Securities until one of the following thresholds is
met: (1) over 90% of the cumulative weight of the Eligible Securities has been included in the Underlying
Index, or (2) the number of included securities reaches 50. The weights of all securities are then rescaled
to construct the final portfolio, seeking to ensure high-conviction exposure to companies with strong and
sustainable profitability and innovation.
The Underlying Index is rebalanced and reconstituted quarterly, with a portfolio turnover cap of 25%.
The Fund’s portfolio is generally rebalanced and reconstituted quarterly, in accordance with the
Underlying Index.
The Fund can use derivative instruments, including exchange-traded futures contracts, to gain exposure to
component securities of the Underlying Index.
The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular
industry or group of industries to approximately the same extent that the Underlying Index is
concentrated. As of September 30, 2024, the Underlying Index is concentrated in the technology sector.

Abacus FCF Innovation Leaders ETF | Equity Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund
holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in
stock prices. The values of equity securities could decline generally or could underperform other
investments. In addition, securities may decline in value due to factors affecting a specific issuer, market
or securities markets generally.
Abacus FCF Innovation Leaders ETF | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk. Investing in securities of small and medium
capitalization companies involves greater risk than customarily is associated with investing in larger,
more established companies. These companies’ securities may be more volatile and less liquid than those
of more established companies. Often, small and medium capitalization companies and the industries in
which they focus are still evolving and, as a result, they may be more sensitive to changing market
conditions. Small and medium capitalization companies may be particularly affected by interest rate
increases, as they may find it more difficult to borrow money to continue or expand operations or may
have difficulty in repaying any loans which are floating rate.
Abacus FCF Innovation Leaders ETF | Index-Based Strategy Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index-Based Strategy Risk. The Fund is managed as an index-based fund that seeks to track the
performance of the Underlying Index. This differs from an actively managed fund, which typically seeks
to outperform a benchmark index. As a result, the Fund may hold the component securities of the
Underlying Index regardless of the current or projected performance of a specific security or the relevant
market as a whole. Maintaining investments in securities regardless of market conditions or the
performance of individual securities could cause the Fund’s returns to be lower than if the Fund employed
an active strategy. The Fund will seek to track the Underlying Index in all market conditions, including
during adverse market conditions when other funds may seek to take temporary defensive measures (such
as investing significantly in cash or cash equivalents). Accordingly, unless the Underlying Index allocates
significant portions of its assets to cash and/or cash equivalents during times of adverse market or
economic conditions, the Fund may be subject to a higher level of market risk during such times than
other funds. Further, the Underlying Index methodology is designed to provide exposure to a limited
number of securities, which results in the Fund holding a more limited number of securities. As a result,
each investment has a greater effect on the Fund’s overall performance and any change in the value of
these securities could significantly affect the value of your investment in the Fund. Additionally, the Fund
generally rebalances and reconstitutes its portfolio in accordance with the Underlying Index and,
therefore, any changes to the Underlying Index’s rebalance or reconstitution schedule will typically result
in corresponding changes to the Fund’s rebalance or reconstitution schedule.
Abacus FCF Innovation Leaders ETF | Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Market Events Risk. The value of securities in the Fund’s portfolio may decline due to daily fluctuations
in the securities markets that are generally beyond the Fund’s control, including the quality of the Fund’s
investments, economic conditions, adverse investor sentiment, lower demand for a company’s goods or
services, and general market conditions. In a declining market, the prices for all securities (including
those in the Fund’s portfolio) may decline, regardless of their long-term prospects. Security values tend to
move in cycles, with periods when securities markets generally rise and periods when they generally
decline. In addition, local, regional or global events such as war, acts of terrorism, the spread of infectious
illness or other public health issue, recessions, natural disasters, or other events could have a significant
impact on the Fund, its investments and the trading of its Shares.
Abacus FCF Innovation Leaders ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Concentration Risk. A fund concentrated in an industry or group of industries is likely to present more
risks than a fund that is broadly diversified over several industries or groups of industries. Compared to
the broad market, an individual industry or group of related industries may be more strongly affected by
changes in the economic climate, broad market shifts, moves in a particular dominant stock or regulatory
changes.
Abacus FCF Innovation Leaders ETF | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. A derivative instrument derives its value from an underlying security, currency,
commodity, interest rate, index or other asset (collectively, “underlying asset”). The Fund’s investments
in derivatives may pose risks in addition to and greater than those associated with investing directly in the
underlying assets, including counterparty, leverage and liquidity risks. Derivatives may also be harder to
value, less tax efficient and subject to changing government regulation that could impact the Fund’s
ability to use certain derivatives or their cost. Derivatives strategies may not always be successful.
•Futures Contracts Risk.  Exchange-traded futures contracts are a type of derivative, which
call for the future delivery of an asset, or cash settlement, at a certain stated price on a
specified future date. Futures contracts involve the risk of imperfect correlation between
movements in the price of the instruments and the price of the underlying assets. In addition,
there is the risk that the Fund may not be able to enter into a closing transaction because of an
illiquid market. Exchanges can limit the number of positions that can be held or controlled by
the Fund or the Adviser, thus limiting the ability to implement the Fund’s strategies. Futures
markets are highly volatile, and the use of futures may increase the volatility of the Fund’s
NAV.

Abacus FCF Innovation Leaders ETF | Index Correlation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Correlation Risk. While the Adviser seeks to track the performance of the Underlying Index
closely (i.e., to achieve a high degree of correlation with the Underlying Index), the Fund’s returns may
not match or achieve a high degree of correlation with the returns of the Underlying Index due to
operating expenses, transaction costs, cash flows, regulatory requirements and/or operational
inefficiencies.
Abacus FCF Innovation Leaders ETF | Index Calculation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Calculation Risk. The Underlying Index relies on various sources of information to assess the
criteria of issuers included in the Underlying Index, including information that may be based on
assumptions and estimates. The Fund, the Index Provider, the Adviser, the Underlying Index calculation
agent and any of their respective affiliates cannot offer assurances that the Underlying Index’s calculation
methodology or sources of information will provide an accurate assessment of included issuers at any
particular time.
Abacus FCF Innovation Leaders ETF | Affiliated Index Provider Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Affiliated Index Provider Risk. The Index Provider is an affiliated person of the Adviser, which poses
the appearance of a conflict of interest. For example, a potential conflict could arise if the Adviser, as an
affiliate of the Index Provider, were to exercise undue influence with respect to regular and/or
extraordinary updates to the methodology or composition of the Underlying Index, including in a manner
that might improve the apparent performance of the Fund relative to the performance of the Underlying
Index. Additionally, potential conflicts could arise to the extent that portfolio managers of the Adviser
become aware of contemplated methodology changes or rebalance activity prior to disclosure to the
public, which could facilitate “front running” on behalf of other funds or accounts managed by the
Adviser with similar exposure. Although the Adviser and the Index Provider have taken steps designed to
ensure that these potential conflicts are mitigated (e.g., via the adoption of policies and procedures that
are designed to minimize potential conflicts of interest and the implementation of informational barriers
designed to minimize the potential for the misuse of information about the Underlying Index), there can
be no assurance that such measures will be successful.
Abacus FCF Innovation Leaders ETF | ETF Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risk. As an exchange-traded fund (“ETF”), the Fund is subject to the following risks:
•Authorized Participants Concentration Risk. The Fund may have a limited number of
financial institutions that may act as Authorized Participants (“APs”). To the extent that those
APs exit the business or are unable to process creation and/or redemption orders, Shares may
trade at a discount to NAV and possibly face delisting.
•Flash Crash Risk. Sharp price declines in securities owned by the Fund may trigger trading
halts, which may result in Shares trading in the market at an increasingly large discount to
NAV during part (or all) of a trading day. Shareholders could suffer significant losses to the
extent that they sell Shares at these temporarily low market prices.
•Large Shareholder Risk.  Certain shareholders, including the Adviser or its affiliates, or
groups of related shareholders, such as those investing through one or more model portfolios,
may own a substantial amount of the Shares. The disposition of Shares by large shareholders,
resulting in redemptions through or by APs, could have a significant negative impact on the
Fund. In addition, transactions by large shareholders may account for a large percentage of
the trading volume on the Exchange and may, therefore, have a material upward or
downward effect on the market price of the Shares.
•Premium-Discount Risk. Shares may trade above or below their NAV. Accordingly, investors
may pay more than NAV when purchasing Shares or receive less than NAV when selling
Shares. The market prices of Shares will generally fluctuate in accordance with changes in
NAV, changes in the relative supply of, and demand for, Shares, and changes in the liquidity,
or the perceived liquidity, of the Fund’s holdings.
•Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market
may pay brokerage commissions or other charges, which may be a significant proportional
cost for investors seeking to buy or sell relatively small amounts of Shares. Although the
Shares are listed on the Exchange, there can be no assurance that an active or liquid trading
market for them will develop or be maintained. In addition, trading in Shares on the
Exchange may be halted.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock To pursue its investment objective, the Fund invests, under normal market circumstances, at least 80% of
its net assets (plus any borrowings for investment purposes) in component securities of the Underlying
Index. The Underlying Index is sponsored and maintained by Abacus FCF Indexes LLC (the "Index
Provider"), an affiliate of Abacus FCF Advisors LLC, the Fund's investment adviser (the "Adviser"). The
Underlying Index is designed to track the performance of a strategy that seeks to provide risk-managed
exposure to exchange-traded funds (“ETFs”) that investment primarily in high yield debt instruments
(also known as “junk bonds”) (“High Yield Bond ETFs”). The Fund intends to maintain a portfolio of
securities that generally replicates the holdings of the Underlying Index.
To be eligible for inclusion in the Underlying Index, a High Yield Bond ETF must: (i) be U.S. listed; (ii)
invest primarily in U.S. high yield debt instruments; (iii) have more than $1 billion in assets under
management (“AUM”); (iv) have an expense ratio of less than 0.50%; and (v) have an investment process
that excludes factors, hedges and long/short strategies. Eligible High Yield Bond ETFs are weighted
based on their expenses (lower expenses increase weighting) and AUM (greater AUM increases
weighting). These securities comprise the “High Yield Bond Portfolio” of the Underlying Index.
The types of high yield debt instruments in which a High Yield Bond ETF may invest include corporate
bonds or other bonds or debt instruments that are generally rated below investment grade, which are those
rated lower than Baa3 by Moody’s Investors Service, Inc. (“Moody’s”) or lower than BBB- by S&P
Global Ratings ("S&P"). High Yield Bond ETFs may invest up to 100% of their respective assets in
instruments generally rated below Caa3 by Moody’s or CCC- by S&P.
The Underlying Index utilizes a proprietary, rules-based methodology that employs a tactical overlay that
is intended to provide downside protection to the High Yield Bond ETF allocations. The tactical overlay
will provide either a “buy signal” or a “sell signal,” which are used to determine whether the Underlying
Index will be in a bullish (i.e., fully invested long position) or defensive posture, respectively. When a
“buy signal” is triggered, the Underlying Index will be comprised entirely of High Yield Bond ETFs.
When a “sell signal” is triggered, the Underlying Index will eliminate 80% of its High Yield Bond ETF
allocations in exchange for ETFs that invest primarily in intermediate-term U.S. Treasury securities and/
or other cash equivalents (“Intermediate-Term Treasury ETFs”). The tactical overlay will provide buy or
sell signals on a daily basis. Please review the portfolio holdings information on the Fund's website at
www.abacusfcf.com to determine whether the Fund is in a bullish or defensive posture prior to making an
investment in the Fund.
To be eligible for inclusion in the Underlying Index, an Intermediate-Term Treasury ETF must: (i) be
U.S. listed; (ii) invest primarily in intermediate-term U.S. Treasury securities (i.e., those with durations
typically between 3.5 and 6 years) and/or other cash equivalents; (iii) have more than $1 billion in AUM;
(iv) have an expense ratio of 0.15% or less; and (v) have an investment process that excludes factors,
hedges and long/short strategies. Eligible Intermediate-Term Treasury ETFs are weighted and ranked
based on their expenses (lower expenses increase weighting) and AUM (greater AUM increases
weighting). These securities comprise the “U.S. Treasury Portfolio” of the Underlying Index.
Allocations to the High Yield Bond Portfolio are rebalanced quarterly and reconstituted annually. The
composition of the U.S. Treasury Portfolio is also rebalanced quarterly and reconstituted annually. The
Fund is generally rebalanced and reconstituted in accordance with the Underlying Index. Allocations
implemented pursuant to the tactical overlay are determined at the close of trading on each business day,
based on the signal triggered, and become effective at the close of trading on the following business day.
The Fund will generally implement tactical overlay allocations in accordance with the Underlying Index.
The Fund can use derivative instruments, including exchange-traded futures contracts, to gain exposure to
component securities of the Underlying Index.
The Adviser may engage in active and frequent trading of the Fund’s portfolio securities to achieve the
Fund’s investment objective.
The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular
industry or group of industries to approximately the same extent that the Underlying Index is
concentrated.

Risk [Text Block] rr_RiskTextBlock An investor may lose money by investing in the Fund.
Abacus Tactical High Yield ETF | Underlying ETFs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Underlying ETFs Risk. In seeking to track the Underlying Index, the Fund invests substantially all of its
assets in High Yield Bond ETFs and/or Intermediate-Term Treasury ETFs (together, the “Underlying
ETFs”). Accordingly, the Fund’s investment performance is directly related to the performance of the
Underlying ETFs. The Fund’s net asset value (or “NAV”) will change with changes in the value of the
Underlying ETFs based on their market valuations. An investment in the Fund will entail more costs and
expenses than a direct investment in the Underlying ETFs. As the Underlying ETFs, or the Fund’s
allocations among the Underlying ETFs, change from time to time, or to the extent that the total annual
fund operating expenses of any Underlying ETF changes, the weighted average operating expenses borne
by the Fund may increase or decrease.
Abacus Tactical High Yield ETF | High Yield (Junk Bond) Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High Yield (Junk Bond) Securities Risk. High yield securities and unrated securities of similar credit
quality are considered to be speculative with respect to the issuer’s continuing ability to make principal
and interest payments and are generally subject to greater levels of credit quality risk than investment
grade securities. High yield securities are usually issued by companies, including smaller and medium
capitalization companies, without long track records of sales and earnings, or with questionable credit
strength. These companies may be particularly affected by interest rate increases, as they may find it more
difficult to borrow money to continue or expand operations, or may have difficulty in repaying floating
rate loans. These fixed-income securities are considered below “investment-grade.” The retail secondary
market for these “junk bonds” may be less liquid than that of higher-rated fixed income securities, and
adverse conditions could make it difficult at times to sell these securities or could result in lower prices
than higher-rated fixed income securities. These risks can reduce the value of the shares of a High Yield
Bond ETF and the income it earns.
Abacus Tactical High Yield ETF | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If a
High Yield Bond ETF invests in illiquid securities or its portfolio securities otherwise become illiquid, it
may reduce the returns of the High Yield Bond ETF because the High Yield Bond ETF may be unable to
sell the illiquid securities at an advantageous time or price. In the event that a High Yield Bond ETF
voluntarily or involuntarily liquidates its portfolio assets during periods of infrequent trading of its
securities, the High Yield Bond ETF may not receive full value for those assets, which will reduce the
value of the High Yield Bond ETF’s shares, and in turn, the value of the Fund’s investment in such
shares.
Abacus Tactical High Yield ETF | U.S. Treasury Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock U.S. Treasury Securities Risk. U.S. Treasury securities may differ from other securities in their interest
rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than
those of other securities. Similar to other issuers, changes to the financial condition or credit rating of a
government may cause the value of an Intermediate-Term Treasury ETF’s investments to decline.
Abacus Tactical High Yield ETF | Index-Based Strategy Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index-Based Strategy Risk. The Fund is managed as an index-based fund that seeks to track the
performance of the Underlying Index. This differs from an actively managed fund, which typically seeks
to outperform a benchmark index. As a result, the Fund may hold the component securities of the
Underlying Index regardless of the current or projected performance of a specific security or the relevant
market as a whole. Maintaining investments in securities regardless of market conditions or the
performance of individual securities could cause the Fund’s returns to be lower than if the Fund employed
an active strategy. The Fund will seek to track the Underlying Index in all market conditions, including
during adverse market conditions when other funds may seek to take temporary defensive measures (such
as investing significantly in cash or cash equivalents). Accordingly, unless the Underlying Index allocates
significant portions of its assets to cash and/or cash equivalents during times of adverse market or
economic conditions, the Fund may be subject to a higher level of market risk during such times than
other funds. Further, the Underlying Index methodology is designed to provide exposure to a limited
number of securities, which results in the Fund holding a more limited number of securities. As a result,
each investment has a greater effect on the Fund’s overall performance and any change in the value of
these securities could significantly affect the value of your investment in the Fund. Additionally, the Fund
generally rebalances and reconstitutes its portfolio, and implements tactical overlay allocations, in
accordance with the Underlying Index and, therefore, any changes to the Underlying Index’s rebalance,
reconstitution or tactical overlay trigger schedule will typically result in corresponding changes to the
Fund’s rebalance, reconstitution or tactical overlay trigger schedule.
Abacus Tactical High Yield ETF | Tactical Overlay Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Tactical Overlay Risk. The Adviser cannot offer assurances that the tactical overlay process employed
by the Underlying Index methodology will achieve its intended results. Investment in a fund that utilizes a
tactical overlay that seeks to minimize risk may not be appropriate for every investor seeking a particular
risk profile. Please review the portfolio holdings information on the Fund's website at
www.abacusfcf.com to determine whether the Fund is in a bullish or defensive posture prior to making an
investment in the Fund.
Abacus Tactical High Yield ETF | Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Market Events Risk. The value of securities in the Fund’s portfolio may decline due to daily fluctuations
in the securities markets that are generally beyond the Fund’s control, including the quality of the Fund’s
investments, economic conditions, adverse investor sentiment, lower demand for a company’s goods or
services, and general market conditions. In a declining market, the prices for all securities (including
those in the Fund’s portfolio) may decline, regardless of their long-term prospects. Security values tend to
move in cycles, with periods when securities markets generally rise and periods when they generally
decline. In addition, local, regional or global events such as war, acts of terrorism, the spread of infectious
illness or other public health issue, recessions, natural disasters, or other events could have a significant
impact on the Fund, its investments and the trading of its Shares.
Abacus Tactical High Yield ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Concentration Risk. A fund concentrated in an industry or group of industries is likely to present more
risks than a fund that is broadly diversified over several industries or groups of industries. Compared to
the broad market, an individual industry or group of related industries may be more strongly affected by
changes in the economic climate, broad market shifts, moves in a particular dominant stock or regulatory
changes.
Abacus Tactical High Yield ETF | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. A derivative instrument derives its value from an underlying security, currency,
commodity, interest rate, index or other asset (collectively, “underlying asset”). The Fund’s investments
in derivatives may pose risks in addition to and greater than those associated with investing directly in the
underlying assets, including counterparty, leverage and liquidity risks. Derivatives may also be harder to
value, less tax efficient and subject to changing government regulation that could impact the Fund’s
ability to use certain derivatives or their cost. Derivatives strategies may not always be successful.
•Futures Contracts Risk.  Exchange-traded futures contracts are a type of derivative, which
call for the future delivery of an asset, or cash settlement, at a certain stated price on a
specified future date. Futures contracts involve the risk of imperfect correlation between
movements in the price of the instruments and the price of the underlying assets. In addition,
there is the risk that the Fund may not be able to enter into a closing transaction because of an
illiquid market. Exchanges can limit the number of positions that can be held or controlled by
the Fund or the Adviser, thus limiting the ability to implement the Fund’s strategies. Futures
markets are highly volatile, and the use of futures may increase the volatility of the Fund’s
NAV.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Active and Frequent Trading Risk. Active and frequent trading of portfolio securities may result in
increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other
transaction costs on the sale of the securities and on reinvestment in other securities, and may also result
in higher taxes if Shares are held in a taxable account.
Abacus Tactical High Yield ETF | Index Correlation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Correlation Risk. While the Adviser seeks to track the performance of the Underlying Index
closely (i.e., to achieve a high degree of correlation with the Underlying Index), the Fund’s returns may
not match or achieve a high degree of correlation with the returns of the Underlying Index due to
operating expenses, transaction costs, cash flows, regulatory requirements and/or operational
inefficiencies.
Abacus Tactical High Yield ETF | Index Calculation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Calculation Risk. The Underlying Index relies on various sources of information to assess the
criteria of issuers included in the Underlying Index and to determine whether a “buy” or “sell” trigger
should be issued, including information that may be based on assumptions and estimates. The Fund, the
Index Provider, the Adviser, the Underlying Index calculation agent and any of their respective affiliates
cannot offer assurances that the Underlying Index’s calculation methodology or sources of information
will provide an accurate assessment of included issuers or the appropriate trigger at any particular time.
Abacus Tactical High Yield ETF | Affiliated Index Provider Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Affiliated Index Provider Risk. The Index Provider is an affiliated person of the Adviser, which poses
the appearance of a conflict of interest. For example, a potential conflict could arise if the Adviser, as an
affiliate of the Index Provider, were to exercise undue influence with respect to regular and/or
extraordinary updates to the methodology or composition of the Underlying Index, including in a manner
that might improve the apparent performance of the Fund relative to the performance of the Underlying
Index. Additionally, potential conflicts could arise to the extent that portfolio managers of the Adviser
become aware of contemplated methodology changes or rebalance activity prior to disclosure to the
public, which could facilitate “front running” on behalf of other funds or accounts managed by the
Adviser with similar exposure. Although the Adviser and the Index Provider have taken steps designed to
ensure that these potential conflicts are mitigated (e.g., via the adoption of policies and procedures that
are designed to minimize potential conflicts of interest and the implementation of informational barriers
designed to minimize the potential for the misuse of information about the Underlying Index), there can
be no assurance that such measures will be successful.
Abacus Tactical High Yield ETF | ETF Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risk. As an ETF, the Fund is subject to the following risks:
•Authorized Participants Concentration Risk. The Fund may have a limited number of
financial institutions that may act as Authorized Participants (“APs”). To the extent that those
APs exit the business or are unable to process creation and/or redemption orders, Shares may
trade at a discount to NAV and possibly face delisting.
•Flash Crash Risk. Sharp price declines in securities owned by the Fund may trigger trading
halts, which may result in Shares trading in the market at an increasingly large discount to
NAV during part (or all) of a trading day. Shareholders could suffer significant losses to the
extent that they sell Shares at these temporarily low market prices.
•Large Shareholder Risk.  Certain shareholders, including the Adviser or its affiliates, or
groups of related shareholders, such as those investing through one or more model portfolios,
may own a substantial amount of the Shares. The disposition of Shares by large shareholders
resulting in redemptions through or by APs could have a significant negative impact on the
Fund. In addition, transactions by large shareholders may account for a large percentage of
the trading volume on the Exchange and may, therefore, have a material upward or
downward effect on the market price of the Shares.
•Premium-Discount Risk. Shares may trade above or below their NAV. Accordingly, investors
may pay more than NAV when purchasing Shares or receive less than NAV when selling
Shares. The market prices of Shares will generally fluctuate in accordance with changes in
NAV, changes in the relative supply of, and demand for, Shares, and changes in the liquidity,
or the perceived liquidity, of the Fund’s holdings.
•Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market
may pay brokerage commissions or other charges, which may be a significant proportional
cost for investors seeking to buy or sell relatively small amounts of Shares. Although the
Shares are listed on the Exchange, there can be no assurance that an active or liquid trading
market for them will develop or be maintained. In addition, trading in Shares on the
Exchange may be halted.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock To pursue its investment objective, the Fund invests, under normal market circumstances, at least 80% of
its net assets (plus any borrowings for investment purposes) in component securities of the Underlying
Index. The Underlying Index is sponsored and maintained by Abacus FCF Indexes LLC (the “Index
Provider”), an affiliate of Abacus FCF Advisors LLC, the Fund’s investment adviser (the “Adviser”). The
Underlying Index is a rules-based equity index designed to track the performance of “real assets” equities
with strong free cash flow return on invested capital (“FCF-ROIC”) and high dividend yield, as identified
by the Index Provider through extensive historical research. The Fund intends to maintain a portfolio of
securities that generally replicates the holdings of the Underlying Index.
The Index Provider currently defines “real assets” equities as common stock, real estate investment trusts
(“REITs”), master limited partnerships (“MLPs”), and American Depositary Receipts (“ADRs”) included
in the “Real Assets Industry Group,” as defined by the Index Provider. The Index Provider currently
classifies the following sectors as within the Real Assets Industry Group, each as defined by a third-party
industry classification system: real-estate related sectors, including diversified, equity and mortgage
REITs; infrastructure-related sectors, including industrial manufacturing and services; commodities
related sectors, including chemical, plastic and rubber materials, manufactured products, and food and
tobacco production; and natural resources related sectors, including upstream energy, downstream and
midstream energy, integrated oil and gas exploration and production, waste management, and mining and
mineral products.
To be eligible for inclusion in the Underlying Index, an equity security must meet the following
requirements (“Eligible Securities”): (i) be included in the Real Assets Industry Group; (ii) be U.S. listed;
(iii) have a 6-month monthly average price volume in the top 45 percentile of the global equity universe;
(iv) have a trading lot size, multiplied by the 6-month average closing price, of less than $100,000; (v)
have reported the following financial statement items within the past 12 months, based on its most recent
financial reports: (a) free cash flow, (b) net income, (c) dividends, (d) total revenue, (e) total assets, and
(f) total equity; (vi) have reported positive free cash flow in the past 12 months; and (vii) not be a target
company in any pending or completed mergers and/or acquisitions within the past 12 months. The
Underlying Index may include securities of issuers of all capitalization sizes.
The Underlying Index utilizes the Adviser’s proprietary Abacus FCF Leaders Model (the “Model”) to
evaluate Eligible Securities and scores them based on FCF-ROIC. The Model assesses a company’s FCF-
ROIC by analyzing factors such as capital expenditure, accruals, cash flow margins, asset turnover, and
other financial metrics. The FCF-ROIC score is then combined with dividend yield to derive the FCF
Real Assets Leaders Score (the “Score”), which helps identify companies with strong and sustainable
profitability and dividend yield.
A target weighting is then assigned to each Eligible Security based on its Score, with adjustments for
company-specific risk using a proprietary factor derived from the historical volatility of each Eligible
Security’s stock price over the preceding 12-month period. The resulting risk-adjusted score is used to
calculate active weights for each security, which are combined with their free-float market capitalization.
The Underlying Index includes those remaining Eligible Securities until one of the following thresholds is
met: (1) over 90% of the cumulative weight of the Eligible Securities has been included in the Underlying
Index, or (2) the number of included securities reaches 50.  The weights of all securities are then rescaled
to construct the final portfolio, seeking to ensure high-conviction exposure to companies with strong and
sustainable profitability, and high dividend yield.
The Underlying Index is rebalanced and reconstituted quarterly, with a portfolio turnover cap of 25%.
The Fund’s portfolio is generally rebalanced and reconstituted quarterly, in accordance with the
Underlying Index.
The Fund can use derivative instruments, including exchange-traded futures contracts, to gain exposure to
component securities of the Underlying Index.
The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular
industry or group of industries to approximately the same extent that the Underlying Index is
concentrated. As of September 30, 2024, the Underlying Index is concentrated in the Real Assets Industry
Group, as described above.

Abacus FCF Real Assets Leaders ETF | Equity Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund
holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in
stock prices. The values of equity securities could decline generally or could underperform other
investments. In addition, securities may decline in value due to factors affecting a specific issuer, market
or securities markets generally.
Abacus FCF Real Assets Leaders ETF | REITs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock REITs Risk. A REIT is a company that pools investor funds to invest primarily in income producing real
estate or real estate related loans or interests. The Fund may be subject to certain risks associated with
direct investments in REITs. REITs may be affected by changes in their underlying properties and by
defaults by borrowers or tenants. Mortgage REITs may be affected by the quality of the credit extended.
Furthermore, REITs are dependent on specialized management skills. Some REITs may have limited
diversification and may be subject to risks inherent in financing a limited number of properties. REITs
depend generally on their ability to generate cash flow to make distributions to shareholders or
unitholders and may be subject to defaults by borrowers and to self-liquidations.
Abacus FCF Real Assets Leaders ETF | Depositary Receipts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to a
direct investment in a foreign security. Returns on investments in foreign securities could be more volatile
than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special
risks, including due to: differences in information available about foreign issuers; differences in investor
protection standards in other jurisdictions; capital controls risks, including the risk of a foreign
jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; political,
diplomatic and economic risks; regulatory risks; and foreign market and trading risks, including the costs
of trading and risks of settlement in foreign jurisdictions. In addition, depositary receipts may not track
the price of the underlying foreign securities, and their value may change materially at times when the
U.S. markets are not open for trading.
Abacus FCF Real Assets Leaders ETF | MLP Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock MLP Risk. An MLP is a publicly traded partnership primarily engaged in the transportation, storage,
processing, refining, marketing, exploration, production, and mining of minerals and natural resources.
MLP common units, like other equity securities, can be affected by macroeconomic and other factors
affecting the stock market in general, expectations of interest rates, investor sentiment towards an issuer
or certain market sector, changes in a particular issuer’s financial condition, or unfavorable or
unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms
of distributable cash flow). Prices of common units of individual MLPs, like the prices of other equity
securities, also can be affected by fundamentals unique to the partnership or company, including earnings
power and coverage ratios.
Abacus FCF Real Assets Leaders ETF | MLP Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock MLP Tax Risk. MLPs taxed as partnerships, subject to the application of certain partnership audit rules,
generally do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a
share of the MLP’s income, gains, losses, deductions and expenses. A change in current tax law, or a
change in the underlying business mix of a given MLP, could result in an MLP being treated as a
corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay
U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S.
federal income tax purposes would have the effect of reducing the amount of cash available for
distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for
U.S. federal income tax purposes, it could result in a reduction in the value of your investment in the Fund
and lower income.
Abacus FCF Real Assets Leaders ETF | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk. Investing in securities of small and medium
capitalization companies involves greater risk than customarily is associated with investing in larger,
more established companies. These companies’ securities may be more volatile and less liquid than those
of more established companies. Often, small and medium capitalization companies and the industries in
which they focus are still evolving and, as a result, they may be more sensitive to changing market
conditions. Small and medium capitalization companies may be particularly affected by interest rate
increases, as they may find it more difficult to borrow money to continue or expand operations or may
have difficulty in repaying any loans which are floating rate.
Abacus FCF Real Assets Leaders ETF | Index-Based Strategy Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index-Based Strategy Risk. The Fund is managed as an index-based fund that seeks to track the
performance of the Underlying Index. This differs from an actively managed fund, which typically seeks
to outperform a benchmark index. As a result, the Fund may hold the component securities of the
Underlying Index regardless of the current or projected performance of a specific security or the relevant
market as a whole. Maintaining investments in securities regardless of market conditions or the
performance of individual securities could cause the Fund’s returns to be lower than if the Fund employed
an active strategy. The Fund will seek to track the Underlying Index in all market conditions, including
during adverse market conditions when other funds may seek to take temporary defensive measures (such
as investing significantly in cash or cash equivalents). Accordingly, unless the Underlying Index allocates
significant portions of its assets to cash and/or cash equivalents during times of adverse market or
economic conditions, the Fund may be subject to a higher level of market risk during such times than
other funds. Further, the Underlying Index methodology is designed to provide exposure to a limited
number of securities, which results in the Fund holding a more limited number of securities. As a result,
each investment has a greater effect on the Fund’s overall performance and any change in the value of
these securities could significantly affect the value of your investment in the Fund. Additionally, the Fund
generally rebalances and reconstitutes its portfolio in accordance with the Underlying Index and,
therefore, any changes to the Underlying Index’s rebalance or reconstitution schedule will typically result
in corresponding changes to the Fund’s rebalance or reconstitution schedule.
Abacus FCF Real Assets Leaders ETF | Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Market Events Risk. The value of securities in the Fund’s portfolio may decline due to daily fluctuations
in the securities markets that are generally beyond the Fund’s control, including the quality of the Fund’s
investments, economic conditions, adverse investor sentiment, lower demand for a company’s goods or
services, and general market conditions. In a declining market, the prices for all securities (including
those in the Fund’s portfolio) may decline, regardless of their long-term prospects. Security values tend to
move in cycles, with periods when securities markets generally rise and periods when they generally
decline. In addition, local, regional or global events such as war, acts of terrorism, the spread of infectious
illness or other public health issue, recessions, natural disasters, or other events could have a significant
impact on the Fund, its investments and the trading of its Shares.
Abacus FCF Real Assets Leaders ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Concentration Risk. A fund concentrated in an industry or group of industries is likely to present more
risks than a fund that is broadly diversified over several industries or groups of industries. Compared to
the broad market, an individual industry or group of related industries may be more strongly affected by
changes in the economic climate, broad market shifts, moves in a particular dominant stock or regulatory
changes.
Abacus FCF Real Assets Leaders ETF | Real Assets Industry Group Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Real Assets Industry Group Risk. The risks of investing in the Real Assets Industry Group include the
risks of focusing investments in the real estate, infrastructure, commodities and natural resources related
sectors, and adverse developments in these sectors may significantly affect the value of the Shares.
Accordingly, the Fund is more susceptible to adverse developments affecting one or more of these sectors
than a fund that invests more broadly, and the Fund may perform poorly during a downturn affecting
issuers in those sectors. Companies involved in activities related to the Real Assets Industry Group can be
adversely affected by, among other things, government regulation or deregulation, global political and
economic developments, energy and commodity prices, the overall supply and demand for oil and gas,
changes in tax zoning laws, environmental issues, and low inflation.
Abacus FCF Real Assets Leaders ETF | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. A derivative instrument derives its value from an underlying security, currency,
commodity, interest rate, index or other asset (collectively, “underlying asset”). The Fund’s investments
in derivatives may pose risks in addition to and greater than those associated with investing directly in the
underlying assets, including counterparty, leverage and liquidity risks. Derivatives may also be harder to
value, less tax efficient and subject to changing government regulation that could impact the Fund’s
ability to use certain derivatives or their cost. Derivatives strategies may not always be successful.
•Futures Contracts Risk. Exchange-traded futures contracts are a type of derivative, which call
for the future delivery of an asset, or cash settlement, at a certain stated price on a specified
future date. Futures contracts involve the risk of imperfect correlation between movements in
the price of the instruments and the price of the underlying assets. In addition, there is the risk
that the Fund may not be able to enter into a closing transaction because of an illiquid market.
Exchanges can limit the number of positions that can be held or controlled by the Fund or
Abacus FCF Advisors LLC, the Fund’s adviser (the “Adviser”), thus limiting the ability to
implement the Fund’s strategies. Futures markets are highly volatile, and the use of futures
may increase the volatility of the Fund’s NAV.

Abacus FCF Real Assets Leaders ETF | Index Correlation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Correlation Risk. While the Adviser seeks to track the performance of the Underlying Index
closely (i.e., to achieve a high degree of correlation with the Underlying Index), the Fund’s returns may
not match or achieve a high degree of correlation with the returns of the Underlying Index due to
operating expenses, transaction costs, cash flows, regulatory requirements and/or operational
inefficiencies.
Abacus FCF Real Assets Leaders ETF | Index Calculation Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Index Calculation Risk. The Underlying Index relies on various sources of information to assess the
criteria of issuers included in the Underlying Index, including information that may be based on
assumptions and estimates. The Fund, the Index Provider, the Adviser, the Underlying Index calculation
agent and any of their respective affiliates cannot offer assurances that the Underlying Index’s calculation
methodology or sources of information will provide an accurate assessment of included issuers at any
particular time.
Abacus FCF Real Assets Leaders ETF | Affiliated Index Provider Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Affiliated Index Provider Risk. The Index Provider is an affiliated person of the Adviser, which poses
the appearance of a conflict of interest. For example, a potential conflict could arise if the Adviser, as an
affiliate of the Index Provider, were to exercise undue influence with respect to regular and/or
extraordinary updates to the methodology or composition of the Underlying Index, including in a manner
that might improve the apparent performance of the Fund relative to the performance of the Underlying
Index. Additionally, potential conflicts could arise to the extent that portfolio managers of the Adviser
become aware of contemplated methodology changes or rebalance activity prior to disclosure to the
public, which could facilitate “front running” on behalf of other funds or accounts managed by the
Adviser with similar exposure. Although the Adviser and the Index Provider have taken steps designed to
ensure that these potential conflicts are mitigated (e.g., via the adoption of policies and procedures that
are designed to minimize potential conflicts of interest and the implementation of informational barriers
designed to minimize the potential for the misuse of information about the Underlying Index), there can
be no assurance that such measures will be successful.
Abacus FCF Real Assets Leaders ETF | ETF Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risk. As an exchange-traded fund (“ETF”), the Fund is subject to the following risks:
•Authorized Participants Concentration Risk. The Fund may have a limited number of
financial institutions that may act as Authorized Participants (“APs”). To the extent that those
APs exit the business or are unable to process creation and/or redemption orders, Shares may
trade at a discount to NAV and possibly face delisting.
•Flash Crash Risk. Sharp price declines in securities owned by the Fund may trigger trading
halts, which may result in Shares trading in the market at an increasingly large discount to
NAV during part (or all) of a trading day. Shareholders could suffer significant losses to the
extent that they sell Shares at these temporarily low market prices.
•Large Shareholder Risk. Certain shareholders, including the Adviser or its affiliates, or
groups of related shareholders, such as those investing through one or more model portfolios,
may own a substantial amount of the Shares. The disposition of Shares by large shareholders
resulting in redemptions through or by APs could have a significant negative impact on the
Fund. In addition, transactions by large shareholders may account for a large percentage of
the trading volume on the Exchange and may, therefore, have a material upward or
downward effect on the market price of the Shares.
•Premium-Discount Risk. Shares may trade above or below their NAV. Accordingly, investors
may pay more than NAV when purchasing Shares or receive less than NAV when selling
Shares. The market prices of Shares will generally fluctuate in accordance with changes in
NAV, changes in the relative supply of, and demand for, Shares, and changes in the liquidity,
or the perceived liquidity, of the Fund’s holdings.
•Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market
may pay brokerage commissions or other charges, which may be a significant proportional
cost for investors seeking to buy or sell relatively small amounts of Shares. Although the
Shares are listed on the Exchange, there can be no assurance that an active or liquid trading
market for them will develop or be maintained. In addition, trading in Shares on the
Exchange may be halted.
