The fund's income is zero because the fund does not generate income on the day of subscription, and it will only generate income after the share is confirmed. So for example, if you buy on T-day, T+ 1 confirms the share to generate income, and T+2 checks the income. And the working day is divided by 15, before 15 is T day, and after 15 (inclusive) is T+ 1 day, which is why sometimes the fund's income is zero for three consecutive days.

In addition, during holidays, the income will not be displayed normally, but will be displayed together on the first working day after holidays.
