Currency: SUM(profit * quantity * point value) of all trades / # of trades

Percent: SUM(profit * quantity / entry price) of all trades  / # of traded lots

Points: SUM(profit * quantity) of all trades / # of trades

Where profit is defined as (exit price – entry price) for long trades and as (entry price – exit price) for short trades, quantity is defined as the number of contracts traded, and point value is defined as the monetary conversion of each point (e.g. 100 for currency pairs).

This statistic returns a value representing the average profit you experience from all of your trades. It is useful for getting an idea of how much you could expect to earn on future trades.
