I guess you are asking to see the current value of your holding. Unfortunately that is not available in this platform. I find that aspect frustrating too. Also bear in mind that the P&L figure does not reduce when performance fees are paid, so you have to deduct those from the figure to get the true P&L.
That’s really bad and your suggestion really good. They should add a column for the net profit where open P&L is deducted by retained and paid performance fee on the open position. (Excluding the fees for closed positions on the same Darwin!)
