Calculate the income on the day of fund redemption. Fund redemption is settled according to the net value of the day, and the net value of the day will be announced after 18:00. This is what the fund calls the principle of unknown price trading. When investors apply for redemption in advance, they don't know the transaction price.

Fund redemption, also known as repurchase, is aimed at open-end funds. Investors directly or through an agency require the fund management company to withdraw part or all of the investment from the fund and remit the repurchase money to the investor's account.
