Add feature to automatically calculate PnL on "open" trades based on time/date and lot size

Hey, I would like to have the feature in the section “Manual Entry” that the PnL gets automatically calculated based on the data that is given from the manually opened position (date/time, asset, lot size (for forex) so for example I would see how much I would have made in the past in some trades.

Actually this needs to be functional in the backtesting feature, but since it’s not fixed yet that would be an alternative feature to see how good my system would perform

Because right now it’s only possible to open positions but they don’t show any automatatically calculated PnL and I would need to manually calculate how much the profit/loss would be.
