how is the Unrealized P/L calculated?
Like let's say i short 400 and it drops a few.. if someone has a short that is lower than my short but is only .. let's say 10 ltc .. is my Unrealized P/L calculated based on that 10 or 10 and the ones behind it?
Just want to make sure when i hit a market close.
It is based on the best bid/ask. I believe it does not take order book depth into consideration. So with sizable positions, be very careful with the market order button. (Same goes for trigger orders like stops)
