Fund prices are not real-time. The price for fund subscription and redemption is the net value of the fund unit on the day of subscription and redemption. The net value of a fund unit refers to the value of each fund, which is a measure of how much the fund is worth. The net value of a fund unit = the total net asset value of the fund/the total shares of the fund unit. Subscriptions and redemptions of open-end funds are carried out at this price.

For example, if the net value of a fund unit is 1.25, it means that the value on that day is 1.25 yuan. Assume that the net value of the customer on the day of participation is 1 and the net value when exiting is 1.25. Without considering the handling fee, the profit is 1.25-1=0.25 yuan/share.
