Margin is the amount of capital required to open a position. It acts as collateral and depends on your chosen leverage and position size.
Margin = Trade Size ÷ Leverage
Example:
To open a $100,000 position with 1:100 leverage, you need:
$100,000 ÷ 100 = $1,000 margin
The margin required is shown in your trading platform before you confirm a trade.
