What is margin in forex trading:

Margin is the small amount of money you need to deposit to open and secure a position. You don’t require to pay the whole amount but only a little percentage. This makes you eligible for holding a position. A broker keeps this percentage of money for as long as the trade is open. This money ensures that you can pay for the loss in the future.

For example, if you have to buy a position worth $1000, you don’t have to pay all of this but only a proportion of it, such as $10.

Free and used margin:

There are two types of margin in forex trading; used margin and free margin. Used margin is the total margin from the sum of all the positions that you hold in trading. In comparison, free margin is that margin that is free to use. Since the used margin implies your investments and the positions that you hold, free margin is the amount that can be used to open some new positions. Free margin can also be withdrawn from your account because it’s the amount that’s not in use for trading.

When free margin is zero:

When you have no funds to open new deposits or all your deposits are invested in holding positions, your free margin is zero. In this case, you can’t buy new positions in forex because you don’t have any usable margins available to secure in that case.
