Can the fund be withdrawn at any time?
As long as it is not a closed-end fund, it can be redeemed at any time, but the time to account depends on the fund type and fund regulations. Generally speaking, money funds, stock funds, index funds, mixed funds and bond funds are all T+ 1 received.
For example, if the fund is redeemed on Monday, it will arrive on Tuesday, but it should be noted that if it is redeemed on Friday, it will not arrive until next Monday, because the fund is not traded on Saturday and Sunday, so if you want to redeem the fund quickly, it is generally recommended to avoid Saturday and Sunday and holidays.
When can I sell the fund I bought that day?
When buying a fund on the same day, it is generally necessary to confirm the share according to the fund before selling it. For example, if an investor buys a stock fund on Monday, he will confirm his share on Tuesday and sell the fund on Wednesday. However, it should be noted that when selling, the fund will be redeemed at T+ 1, so the share will be sold on Thursday (the above example does not include holidays).
Secondly, it should be noted that the selling rates of funds are generally divided into 0~7 days, 7~365 days, 365~730 days and more than 730 days. The longer the holding time, the lower the selling fee rate.
