Average Price (Column)

The average price of the position currently held. For example, if you bought 1000 shares at 265 (total price 265,000) and 1000 shares at 258 (total price 258,000), the average price would be 261.50 (523,000 divided by 2000).

  For futures, positions are not closed intraday (they are netted intraday) and, therefore, p/l is not realized intraday.  The average price (and unrealized p/l) represents accrued p/l from the overall net position, not just the most recently opened portion of the day's netted position.
