In the Profit & Loss column, is this figure based on the last trading price, or is it based on true exit price (ie. the bid price if you are long a stock, the ask price if you are short a stock). If its the last trading price, I recommend changing it to the true exit price. Also it seems to not match the net liquidity under accounts. They are based on different numbers? Someone know for sure? I would test it myself, but I've had too many positions lately to know for sure.
