FAQ

How do I calculate forex margin?

Margin equals the notional value of the trade divided by your leverage. Notional value is lot size times the contract size (usually 100,000 units per standard lot) times the price. For 1 lot of EUR/USD at 1.08 with 1:100 leverage, the margin is 100,000 times 1.08 divided by 100, which is about 1,080 in your account currency.

What is leverage in forex?

Leverage lets you control a larger position with a smaller margin. 1:100 means $1 of margin controls $100 of position. Higher leverage means a smaller margin requirement but faster losses, so size off your risk per trade, not the maximum leverage on offer.
