There is no time limit for fund withdrawal, that is, redemption of funds. The time to redeem the fund is different, and the time to receive the funds is different. Generally speaking, investors will redeem the fund before three o'clock on the trading day, and the funds will arrive on T+2. If they redeem the fund after three o'clock on the trading day, the funds will arrive at T+3. If the fund is redeemed on weekends and holidays, it is equivalent to redemption before 3: 00 on the trading day after holidays.
General open-end funds can be purchased and redeemed at any time. Closed-end funds cannot be redeemed in advance. In addition, it takes T+2 days to redeem the newly purchased fund.
