Open P&L refers to the unrealized profit or loss of an open position. The calculation is derived as below: 1. Long Position: Open P&L = Open Positions (Last Done Price - Entry Price) x Quantity x Contract Multiplier 2. Short Position: Open P&L = Open Positions (Entry Price - Last Done Price) x Quantity x Contract Multiplier To put it simply, it is the paper gain or loss represented by the current market value and price paid; also known as unrealized P and L. For example, if an investor buys 1 contract of ES expiring December of 24 at 4100 and the current market price is 4200, you will have an unrealized P and L of 100 multiplied by the multiplier of $50 i.e. (100*$50 = $5000) minus fees and commission. Note: Figures might differ as fees are not included. |
