buying before 15: on the same day is the net value of that day

the income will be available at around 21: the next day.

if the original fund is 1, yuan and you buy another 1, yuan the next day, the original fund will also generate income on the same day, which has no effect on the later purchases.

Just look at the income later. The income from the two purchases will be displayed together. For example, if the original 1, yuan is increased by 1% on the same day, it will be 1 yuan. When you buy 1 yuan on the same day, the handling fee will be 1.5, then you will see the income of this day later.
