ROI Pivot Table is a special grid where you can see monthly return on investment values based on the total equity list.
The monthly values are calculated with the following formula:
ROI value = (Ending equity - Starting Equity - Offset) / Starting Equity where
Ending Equity - equity(net asset) value at the end of the month
Starting Equity - equity value at the end of the previous month
Offset - sum of deposits and withdrawals during the month
