Hi @MonkInTrade Realized profit is the total gross profit (without brokerage and charges). So in this case the total gross profit will be Rs. 330 (profit with brokerage consideration) + Rs. 120 (brokerage charges) = Rs. 450.
The sole purpose of showing realized profit is to enable traders assess their strategy, which has to be independent of brokerage and other charges
