Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<b>Portfolio Turnover </b>
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund may pay transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in total annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. Because the Fund had not commenced operations prior to the date of the Prospectus, there is no portfolio turnover information quoted for the Fund.

Other Expenses, New Fund, Based on Estimates [Text]	rr_OtherExpensesNewFundBasedOnEstimates	The Fund’s “Other Expenses” have been estimated to reflect expenses expected to be incurred during the first fiscal year.
Expense Example [Heading]	rr_ExpenseExampleHeading	<b>Expense Example </b>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of owning Shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell 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 (except that the Example incorporates the fee waiver arrangement for only the first year). The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	<b>Principal Investment Strategies </b>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a broad range of U.S. dollar denominated bonds. The Fund primarily invests in obligations issued or guaranteed by the U.S. Government, its agencies, authorities, instrumentalities or sponsored enterprises (“U.S. Government Securities”), obligations of U.S. banks, corporate notes, commercial paper and other short-term obligations of U.S. companies, states, municipalities and other entities, fixed and floating rate mortgage-backed securities, asset-backed securities, collateralized loan obligations and repurchase agreements. The Fund may also invest in U.S. dollar-denominated obligations issued or guaranteed by foreign banks, companies and governments or their agencies, authorities, instrumentalities or sponsored enterprises. The Fund will generally focus its investments in securities of issuers that, at the time of purchase, have a short-term credit rating of at least investment grade by at least one nationally recognized statistical rating organization (“NRSRO”) (at least A-2, P-2, or F2 by Standard & Poor’s Ratings Services (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch Ratings, Inc. (“Fitch”), respectively), have a long-term credit rating of at least investment grade by at least one NRSRO (at least BBB-, Baa3, or BBB by Standard & Poor’s, Moody’s or Fitch, respectively) if such securities only maintain long-term ratings, or, if unrated, are determined by the Investment Adviser to be of comparable credit quality at the time of purchase. The Fund may also rely on the credit quality of a guarantee or demand feature in determining the credit quality of a security supported by the guarantee or demand feature. The Fund will concentrate its investments in the financial services group of industries. Therefore, under normal circumstances, the Fund will invest more than 25% of its total assets in securities issued by companies in the financial services group of industries and repurchase agreements secured by such obligations. Under normal circumstances, the Fund’s effective duration is expected to be one year or less. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. In computing duration, the Fund will estimate the duration of obligations that are subject to prepayment or redemption by the issuer, taking into account the influence of interest rates on prepayments and coupon flows. This method of computing duration is known as “option-adjusted” duration. The Fund is an actively managed exchange-traded fund (“ETF”), which is a fund that trades like other publicly-traded securities. The Fund is not an index fund and does not seek to replicate the performance of a specified index. THE FUND IS NOT A MONEY MARKET FUND AND DOES NOT ATTEMPT TO MAINTAIN A STABLE NET ASSET VALUE.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	The Fund will concentrate its investments in the financial services group of industries. Therefore, under normal circumstances, the Fund will invest more than 25% of its total assets in securities issued by companies in the financial services group of industries and repurchase agreements secured by such obligations.
Risk [Heading]	rr_RiskHeading	<b>Principal Risks of the Fund </b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Cash Transactions Risk.  Unlike certain ETFs, the Fund expects to effect its creations and redemptions primarily for cash, rather than primarily for in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF which generally are able to make in-kind redemptions and avoid realizing gains in connection with transactions designed to raise cash to meet redemption requests. Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). Financial Services Industry Group Risk.  An adverse development in the financial services industry group, including U.S. and foreign banks, broker-dealers, insurance companies, finance companies (e.g., automobile finance) and related asset-backed securities, may affect the value of the Fund’s investments more than if the Fund were not invested to such a degree in this industry group. Companies in the financial services industry group may be particularly susceptible to certain economic factors such as interest rate changes, fiscal, regulatory and monetary policy and general economic cycles. Floating and Variable Rate Obligations Risk.  For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation’s interest rate payment not being immediately impacted by a decline in interest rates. Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the “reference rate”), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time. Foreign Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls (including repatriation restrictions), sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. In addition, the Fund will be subject to the risk that an issuer of non-U.S. sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due. Industry Concentration Risk.  The Fund concentrates its investments in the financial services group of industries, which has historically experienced substantial price volatility. This concentration may subject the Fund to greater risk of loss as a result of adverse economic, business, political, environmental or other developments than if its investments were diversified across different industries. Interest Rate Risk.  When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund. Large Shareholder Risk.  Certain shareholders, including other funds advised by the Investment Adviser, may from time to time own a substantial amount of the Fund’s Shares. In addition, a third party investor, the Investment Adviser or an affiliate of the Investment Adviser, an authorized participant, a lead market maker, or another entity (i.e., a seed investor) may invest in the Fund and hold its investment solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. Any such investment may be held for a limited period of time. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund, including on the Fund’s liquidity. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Cboe BZX Exchange, Inc. (the “Exchange”) and may, therefore, have a material upward or downward effect on the market price of the Shares. Liquidity Risk.  The Fund may invest in securities or instruments that trade in lower volumes and may make investments that are less liquid than other investments. Also, the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security or instrument at all. An inability to sell one or more portfolio positions can adversely affect the Fund’s value. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Redemptions by large shareholders (including seed investors) may have a negative impact on the Fund’s liquidity. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Market Trading Risk.  The NAV of the Fund and the value of your investment may fluctuate. Market prices of Shares may fluctuate in response to the Fund’s NAV, the intraday value of the Fund’s holdings and supply and demand for Shares. The Fund faces numerous market trading risks, including disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares. Any of these factors, among others, may result in Shares trading at a significant premium or discount to NAV, which will be reflected in the intraday bid/ask spreads and/or the closing price of Shares as compared to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Additionally, in stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. Mortgage-Backed and Other Asset-Backed Securities Risk.  Mortgage-related and other asset-backed securities are subject to certain additional risks, including “extension risk” (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and “prepayment risk” (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk. Municipal Securities Risk.  Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds). Seed Investor Risk.  GSAM and/or its affiliates may make payments to one or more investors that contribute seed capital to the Fund. Such payments may continue for a specified period of time and/or until a specified dollar amount is reached. Those payments will be made from the assets of GSAM and/or such affiliates (and not the Fund). Seed investors may contribute all or a majority of the assets in the Fund. There is a risk that such seed investors may redeem their investments in the Fund, particularly after payments from GSAM and/or its affiliates have ceased. As with redemptions by other large shareholders, such redemptions could have a significant negative impact on the Fund, including on the Fund’s liquidity and the market price of the Fund’s shares. U.S. Government Securities Risk.  The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future. Valuation Risk.  The sale price the Fund could receive for a security may differ from the Fund’s valuation of the security. The Fund relies on various sources to calculate its NAV. The information may be provided by third parties that are believed to be reliable, but the information may not be accurate due to errors by such pricing sources, technological issues or otherwise. NAV calculation may also be impacted by operational risks arising from factors such as failures in systems and technology.
