**What is profit/loss? **

Profit/Loss is the total "paper" (or unrealized) profit or loss for all open positions. Note that for long positions you have a paper profit (loss) if your opening cost is lower (higher) than current valuation. For short positions you have a paper profit (loss) if your opening cost is higher (lower) than current valuation. The unrealized profit or loss does not affect your currency balances until the positions are closed.

**Calculating Profit/Loss**

Suppose you have two short positions open. One has an opening cost of $3,000 and a current value of $2,500. This position has a paper profit of $500. The other has an opening cost of $2,000 and a current value of $2,100. This position has a paper loss of $100. Your total profit on the two positions is $400.
