The P/L summary shows the Instrument P/L for all open positions; for each trading day. That is to say, the difference between the Position Value at the start of the trading day and the Position Value at the end of the trading day, for open positions. The values are shown on instrument levels (as Instrument P/L) and group levels (Cumulative P/L) e.g. for a given asset type or sector, as the sum of all Instrument P/L for a specific asset group.
Instrument P/L is calculated based on Mark-to-market principles. Note that this might not be the principle used by your local tax authorities, therefore, the figures presented should only serve as an indication of profit/loss in the period. Always reference the profit/loss calculation against the underlying trades found in the Trades Report.
