On the MT4 platform, the deposit is referred to as a "prepayment". Margin refers to your open position and must be paid in a lump sum. ETO Markets Limited provides up to 400 margin leverage. The margin requirement is calculated in the base currency and then converted into US dollars at the spot price. If your available margin is lower than the margin you need, you will not be allowed to open any transactions. The available margin is the difference between your account's net worth and the margin for your open position.
The margin is calculated by the following formula:
Required margin=(current market price x transaction quantity)/account leverage
For example:
If you want to open your position at the current price of EUR/USD (1.35645) for an order quantity of 0.1 lots (10000 basic units), with an account leverage of 400 times - your required margin calculation is as follows:
(1.35645 x 10000)/400=33.91 USD
In this example, the next 0.1 orders require a deposit of $33.91, so the available deposit in your account needs to be at least $33.91 before you can successfully open the position.
