How do I calculate the P/L (profit or loss) per trade?

To calculate the profit or loss for a given trade, please use the formula below: 

Buy Trade: (Close rate - Open rate) X Units X USD exchange rate = P/L 

Sell Trade: (Open rate - Close rate) X Units X USD exchange rate = P/L 

Instruments that are traded in US Dollars do not require a conversion and therefore the USD exchange rate value will be 1.
