Margin Required

Margin is the collateral required to open and maintain a leveraged position.

Required Margin = (Position Size × Price) / Leverage

Or equivalently: Required Margin = Notional Value × Margin Rate Margin Rate = 1 / Leverage

Common leverage ratios:

  • Forex (US retail): 50:1 (2% margin)
  • Forex (non-US): 200:1–500:1 (0.2–0.5% margin)
  • Stocks (Reg T): 2:1 (50% margin)
  • Futures (day trade): 10:1–20:1 (5–10% margin)
  • Crypto: 2:1–100:1 varies by exchange

Margin call territory:

  • When your equity drops below maintenance margin (usually 50% of initial)
  • Free margin = Equity − Used margin
  • Margin level = (Equity / Used Margin) × 100%
  • Below 100% margin level = margin call risk
