Whether it is a weekly rise or a monthly rise, there is a start time and an end time.

For weekly income, the net value on the last day of last weekend is the initial value, and the net value on the last day of this weekend is the final value.

Then the weekly increase = (initial value-final value)/initial value

The same is true of the monthly increase. The net value on the last trading day of last month is the initial value and the last trading day of this month is the final value. The formula is as above. The percentage of the last unit.
