I am new to this, have ignored all advise for attending a course first and have a question once again. On the log on page, in the SFF portfolio the daily P/L differs from the move (for the day) in the watchlist. Why?
The daily profit/loss value is the difference between the previous MTM price and the current bid (if long) or offer (if short). The watch list price is always the difference between the MTM and offer price.
