The DayPnL figure includes all components that affect the customer balance. The current cash balance of a customer is computed from the following equation:
Cash Now = Yesterday Cash + Realised PnL + Deposits – Withdrawals
DayPnL is computed from the following equation:
DayPnL = Unrealised PnL Now + Realised PnL – Yesterday Unrealised
Commission and SWAP amounts are also included in DayPnL, as these are part of Realised PnL. However, IB Rebate is not included as it does not affect customer balance.
