What does ‘margin’ mean and how is this calculated?
This is the amount of money required in your account in order to open a position. Margin is calculated based on the current price of the base currency against USD, the size (volume) of the position and the leverage applied to your trading account.
If you do not have sufficient free equity available, you will be unable to open a position on the trading platform. The free margin amount shown in the trading platform is the amount you have available to use should you wish to open additional positions.
