What is Margin in Forex?
Margin is the amount of money your broker requires as collateral to open a leveraged position. It's not a fee — it's held by your broker while your trade is open.
With 1:100 leverage, you only need $1,000 margin to control a $100,000 position. This amplifies both profits and losses.
Understanding margin requirements helps you avoid margin calls and ensures you have enough free margin for additional trades and to withstand market fluctuations.
