Risk [Text Block]	Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.
Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Investment Risk. You could lose money by investing in the fund. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.
New Fund Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	New Fund Risk. The fund is a new ETF and has only recently commenced operations and therefore has limited operating history on which investors can base their investment decision. Additionally, due to the fund’s small asset base, certain of the fund’s expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. There can be no assurance that the fund will grow to or maintain an economically viable size, in which case the fund may cease operations. In such an event, your interest in the fund may be liquidated at an inopportune time.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk. Any actively managed fund is subject to the risk that its investment adviser will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its investment objective. The fund’s investment adviser applies its own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results. The investment adviser’s maturity decisions will also affect the fund’s yield, and potentially could affect its share price. To the extent that the investment adviser anticipates interest rate trends imprecisely, the fund’s yield at times could lag the yields of other money market funds.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest Rate Risk. Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. Changes or the anticipation of changes in interest rates also may affect the fund’s share price: a rise in interest rates generally causes the fund’s share price to fall. The longer the fund’s portfolio duration, the more sensitive to interest rate movements its share price is likely to be. Also, a change in a central bank’s monetary policy or economic conditions, among other things, may result in a change in interest rates, which could have sudden and unpredictable effects on the markets and significantly impact the value of fixed-income securities in which the fund invests. A sudden or unpredictable rise in interest rates may cause volatility and the value of fixed-income securities to decline. Volatility in the market may decrease liquidity in the money market securities markets, making it more difficult for the fund to sell its money market investments at a time when the investment adviser might wish to sell such investments. Decreased market liquidity also may make it more difficult to value some or all of the fund’s money market securities holdings.
Credit Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Credit Risk. A decline in the credit quality of an issuer, guarantor or liquidity provider of a portfolio investment or a counterparty could cause the fund to lose money or underperform. The fund could lose money if, due to a decline in credit quality, the issuer, guarantor or liquidity provider of a portfolio investment or a counterparty fails to make, or is perceived as being unable or unwilling to make, timely principal or interest payments or otherwise honor its obligations. Even though the fund’s investments in repurchase agreements are collateralized at all times, there is some risk to the fund if the other party should default on its obligations and the fund is delayed or prevented from recovering or disposing of the collateral. The credit quality of the fund’s portfolio holdings can change rapidly in certain market environments and any downgrade or default on the part of a single portfolio investment could cause the fund’s share price or yield to fall.
Repurchase Agreements Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Repurchase Agreements Risk. When the fund enters into a repurchase agreement, the fund is exposed to the risk that the other party (i.e., the counterparty) will not fulfill its contractual obligation. In a repurchase agreement, there exists the risk that, when the fund buys a security from a counterparty that agrees to repurchase the security at an agreed upon price (usually higher) and time, the counterparty will not repurchase the security.
Government Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Government Securities Risk. U.S. government securities include securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) or other Government-Sponsored Enterprises (GSEs)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the fund. Securities issued or guaranteed by U.S. government related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future. U.S. government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.
Money Market Fund Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Money Market Fund Risk. The fund is not designed to offer capital appreciation. In exchange for their emphasis on capital preservation and liquidity, money market investments may offer lower long-term performance than stock or bond investments.
Cash Transaction Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cash Transaction Risk. The fund issues and redeems shares at the fund’s NAV only in large blocks of shares (Creation Units). Purchases and redemptions of Creation Units that are made primarily with cash, rather than through in-kind delivery of portfolio securities, may cause the fund to incur additional costs that the fund may not have incurred if the fund had made purchases or redemptions in-kind. To the extent that the transaction fees payable by the Authorized Participant do not offset the costs associated with a cash transaction, the fund’s performance may be negatively impacted.
Market Trading Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Trading Risk. Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.
Shares of the Fund May Trade at Prices Other Than NAV [Member]
Prospectus [Line Items]
Risk [Text Block]	Shares of the Fund May Trade at Prices Other Than NAV. Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. An investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The market price of fund shares may deviate, sometimes significantly, from NAV during periods of market volatility or market disruption.
