Your Profit and Loss is automatically calculated in your MT4 platform. To manually calculate your Profit or Loss, you can use the following formula:
(Closing Rate – Opening Rate) x (Closing {quote} / {home currency}) x Units
Use the following information as an example:
Home Currency: USD
Currency Pair: GBP/CHF
Base = GBP; Quote = CHF
Quote / Home Currency = CHF/USD = 1.1025
Opening Rate = 2.1443
Closing Rate = 2.1452
Units = 1000
To calculate the profit/loss:
(2.1452 – 2.1443) x (1.1025) x 1000
Your profit = $0.99225
