What is Margin in Forex Trading?

Margin is the amount of money required in your trading account to open and maintain a leveraged position. Think of it as a good-faith deposit that your broker holds while you control a much larger position in the market. Understanding margin is essential for managing risk and avoiding unexpected account closures.

How Margin Works

When you trade forex with leverage, you don't need the full value of your position. Instead, your broker requires a percentage as margin. For example, with 100:1 leverage, you need just 1% margin to control a position:

• Position size: $100,000
• Required margin (1%): $1,000
• Your control: Full $100,000 position

The remaining funds in your account serve as a buffer against losses. This is your equity, which fluctuates as your trades move in profit or loss.

Types of Margin

Understanding different margin terms helps you manage your account effectively:

• Used Margin: The total amount currently held for your open positions
• Free Margin: Available funds to open new positions or absorb losses
• Margin Level: The ratio of equity to used margin, expressed as a percentage

Margin Risk Management

Proper margin management is critical to avoid margin calls and protect your account. Never use all available margin at once. Professional traders typically use only 10-20% of their available margin to maintain a safety buffer. Monitor your margin level regularly, especially during volatile market conditions when prices can move rapidly against your positions.

Practical tip: design position sizes so that a cluster of losing trades cannot breach broker stop‑out thresholds. Track margin usage by strategy and instrument to avoid accidental concentration.
