  • Position - Shows your position in the instrument.

  • Market Value - Equal to the position * market price.

  • Avg Price - The average price is calculated by dividing your cost (execution price + commission) by the quantity of your position. This value is then used to determine your unrealized P&L. Right-click the field name and select Configure Precision to specify additional decimal places that will display as superscript.

  • P&L - Shows your profit and loss for the current day. You can elect to show New Position P&L displayed as P&L (N) which shows P&L only for transactions executed today, or Daily P&L which includes all open positions.

  • Unrealized P&L - The difference between the current market value and the average price of your position.

Select "Display Both" from the right-click menu to show the unrealized P&L as both a value and a percentage of the initial investment.

  • Realized P&L - Shows your actual profit or loss on closed positions, which is the difference between your entry execution cost (execution price + commissions to open the position) and exit execution cost (execution price + commissions to close the position).

  • Cost Basis - (the current position x average price).

Daily P&L Calculation:

PositionNow * PriceNow - positionAtResetTime * priceAtResetTime + NetAmountTraded

  • For instruments that open and close the same day, ResetTime is five minutes before midnight in the time zone of the instrument.

  • For instruments that open today and close tomorrow (trade through midnight) Reset Time is five minutes before it opens for trading, in the time zone of the instrument.
