How do I calculate required margin for FX trades?

Margin Required = Volume in Lots x Contract Size x Margin Requirement Contract size for FX
(100,000)

Example: Assume you have a EUR MT4 Account with 1:100 leverage.

You want to enter a 1 lot sell trade for AUDJPY:1 Lot x 100,000 x 1% = 1,000 AUD

Required Margin -Since AUD is the base of the currency pair, we need to convert to EUR by dividing by the EURAUD rate, which is 1.59106 for example:1,000 ÷ 1.59106 = 628.51 Required Margin in EUR.
