Important: Outside market trading hours the ask/bid prices can differ from regular ask/bid prices. This influences the display of the current open P/L. Usually when the markets are open this resolves itself automatically. We do not want to ignore this ask/bid prices since it is possible that the market opens with a gap and this P/L become realized.
