It is more appropriate to sell the fund a few minutes before 3 pm, because the fund is not traded in real time, and the share can only be determined on the second trading day of the day, which is calculated according to the net value of the fund on the redemption day.

Investors can probably judge the rise and fall of the fund a few minutes before 3 pm. On that day, the net value of the fund rose, and they can get the income of the day when they sell it. If the fund's net value falls that day, investors can wait until the trading day when the fund's net value rises.
