Forex Margin and Margin Level Explained
Margin is the collateral your broker holds to keep leveraged positions open. Margin level shows how much buffer remains before a margin call.
Forex margin is collateral your broker reserves to keep a leveraged position open. It is not a fee — it is a hold on your equity that affects how much buffer remains before a margin call.

Core margin terms
Required margin
Amount locked when you open a position. Often approximated as notional value divided by leverage, though broker formulas vary by symbol and tier.
Free margin
Equity minus used margin — available to open new trades or absorb floating loss.
Margin level
Typically (equity ÷ used margin) × 100%. When it falls toward broker thresholds, you may face stop-out.
Illustrative margin calculation
Buy 1 standard lot EURUSD at 1.1000 with contract size 100,000 and leverage 1:100. Notional ≈ $110,000. Required margin ≈ $110,000 ÷ 100 = $1,100 before broker-specific adjustments.

Margin calls and stop-out
If floating losses reduce equity enough, margin level drops. Brokers may close positions automatically at stop-out levels defined in terms — read them before trading volatile events like CPI.
