The fixed investment of the fund is related to the net value of the fund unit. Because your monthly fixed investment is certain, when the net value of the fund unit is high, you will buy less fund shares this month, and when the net value of the fund unit is low, you will buy more fund shares.

It is suggested that if the fixed investment bank has an irregular quota, it can also choose the date of fixed investment every month. For example, when the net value of the fund unit is low every month, choose to deduct money.

For example, ICBC's fixed investment can be successfully deducted once within one month, no matter which day.
