To calculate the FX margin requirement, you will require the following formula:
(Market quote * Volume) / Leverage = $Margin Requirement
Example
The current EURUSD price is quoted as 1.13729, and we would like to trade one standard lot (100,000) using our account leverage of 1:100
The calculation would be (1.13729 * 100,000) / 100 = -$1137.30 USD Note: If the base currency of your account is not in USD, this amount can simply be converted into the corresponding currency AUD, GBP, NZD etc.
