Margin is the amount of money required to open a leveraged position. It’s not a fee — it’s a security deposit that your broker holds while the trade is open.

How Margin Works

With 1:100 leverage:

  • Position: 1 lot EUR/USD = $100,000
  • Margin required: $100,000 / 100 = $1,000

Margin Levels

LevelMeaning
100%+Normal trading
100%Margin call warning
Below 50%Stop out (positions auto-closed)

Key Terms

  • Used Margin — Collateral for open positions
  • Free Margin — Available for new positions
  • Margin Level — (Equity / Used Margin) × 100%

Example

  • Account: $10,000
  • Open 0.5 lot EUR/USD
  • Used margin: $542
  • Free margin: $9,458
  • Margin level: 1,845%

Margin Call & Stop Out

When equity drops too low:

  1. Margin Call (100%) — Warning to add funds
  2. Stop Out (50%) — Broker auto-closes positions

Key Points

  • Higher leverage = Lower margin requirement
  • Margin is released when you close the position
  • Always maintain adequate free margin
