Frequently Asked Questions

What is margin in forex trading?

Margin is the amount of your account balance your broker sets aside to open and maintain a leveraged position. It is not a fee—it is collateral. The rest of the position size is effectively borrowed via leverage.

How does leverage affect required margin?

Higher leverage means less margin is required for the same position size, because each unit of your capital controls more notional exposure. Lower leverage requires more margin for the same trade.

Is the margin shown here exactly what my broker will charge?

This tool uses simplified notional and currency conversion assumptions for education. Brokers may use live prices, different contract specs, hedging rules, or additional margin buffers—always check your platform's margin display before trading.

What happens if margin is insufficient?

If your equity falls below the broker's margin requirements, you may face a margin call or automatic liquidation of positions. Risk management and position sizing help keep margin usage within a safe range.
