Margin is the amount of money that traders have to deposit and keep on the account when they open a position. This amount is not a fee or transaction cost. We determine our margin requirements by taking a percentage of the notional trade size. For example, if you want to open a position for $10,000 (0,1 lots) and the leverage on your account is 1:100, the required margin equals to $100. Like in a bank account, the money is stored in the specific currency. You can’t change it. If you want another currency, you need to open a new account. There is also a reporting currency which you can change in your profile. This currency is the currency used to display the consolidated reports across all your accounts. For example, you may have one account in GBP, another account in USD and your reporting currency in EUR, so you see your total balance across your two accounts in EUR. It is allowed to have up to 4 live accounts at the same time.
