2. Accumulated net value of the day =( 1+ current rate of return) × accumulated net value of yesterday.
3. Calculated on the first day of the account, the accumulated net value of yesterday is 1 by default.
4. As long as one of "Current Equity+Current Withdrawal" and "Yesterday Equity+Current Deposit" is 0, the cumulative net value of the current day is equal to yesterday's cumulative net value by default.
5. Cumulative yield of the day = (cumulative net value of the day-1)× 100%.
This is their calculation formula.
