How to Calculate Free Margin in Forex

How to calculate free margin in Forex is done through some math. You can calculate free margin just by looking on the Metatrader 4 trading platform and make calculation in your head or by allowing trading platform to do that for you.

You need to take two numbers to calculate free margin in Forex. I have made simple example to show you how to do it.

Used margin is $1,000 and rest of the money is free margin to open new position.

Free margin = equity – margin on open positions

Free margin = $9,880.31 – $1,000

Free margin = $8,880.31

Free margin represents the amount of money that is free to use for new positions. If I want to open new trade, one part of free margin amount would be used to set aside as a margin.

When I open new trade, margin will increase from $1,000 by certain amount that is defined by the margin percentage requirement.

Second Trade for Free Margin Example

Here is another trade where I have open the trade to demonstrate you how does the margin and free margin change when the new order is open.

After I have open new position my Free Margin is decreased by $1,000. That is the amount my Margin is increased, from $1,000 to $2,000.

Now I am left with $7,874.23 for new trades if I decide to open them.

Free margin = equity – margin on open positions

Free margin = $9,874.23 – $2,000

Free margin = $7,874.23

Free Margin is Floating Value

Have in mind, and that is shown on examples, that free margin is floating. Meaning, the amount varies as the trade results varies.

If my trades are profitable then my equity will increase. When the equity increases then the free margin will increase.

That means I can open more trades because I have free amount of money for more margin.

When the trades are losing ones my free margin will decrease because the equity will decrease. That will leave less space for me to open new trades.
