In trading, the metric shows how much money a position is currently making or costing. One distinction matters, and many displays show it only in small print: realised PnL is the result of a closed trade, while unrealised PnL is a pure paper value that changes with every price tick. Only the realised gain lands in your account, and in Germany only that gain counts for the tax office.
