Investors buy funds before the trading day 15:00, and settle according to the net value of the day; After 15:00, it shall be settled according to the net value of the next trading day.

Fund trading is based on the principle of unknown price. Investors don't know the specific transaction price before buying, so they can only make an estimate. But the final transaction is based on net value, and the valuation can only be used as a reference. There will be some deviations in the general valuation.
