1. Redeem a few minutes before closing. Fund transactions are calculated according to the net value at the close. The fluctuation of the fund on that day depends on the estimated net value of the fund. When the estimated net value of the fund rises, investors can redeem it. When the estimated net value of the fund falls, investors can not redeem it.

2. Redemption with a holding period of more than 7 days: The redemption fee of the Fund varies according to the holding time. Generally, the longer the holding time, the lower the redemption fee. If the holding period is less than 7 days, the redemption fee is 1.5%, which is not cost-effective.

3. High redemption: the fund mainly earns the bid-ask spread, and only by buying at a low price and selling at a high price can it earn income. When the fund is at a high level, investors can redeem it and don't chase after it.
