A margin call is a notification from your broker that your account equity has fallen below the minimum required margin level to maintain your open positions. When triggered, you must either deposit additional funds or close positions. If neither action is taken, the broker will automatically liquidate your positions at a predetermined stop-out level to prevent further losses.
How Margin Calls Work
When you open a leveraged forex trade, your broker sets aside a portion of your account as used margin — collateral for the position. The remaining funds are free margin. Your margin level is the ratio between equity and used margin.
Margin level formula
Margin Level = (Account Equity / Used Margin) × 100%
Margin call example
| Step | Event | Equity | Used Margin | Margin Level |
|---|---|---|---|---|
| 1 | Open 1.00 lot EUR/USD | $10,000 | $1,000 | 1,000% |
| 2 | Floating loss: -$5,000 | $5,000 | $1,000 | 500% |
| 3 | Floating loss: -$8,000 | $2,000 | $1,000 | 200% |
| 4 | Floating loss: -$9,000 | $1,000 | $1,000 | 100% — Margin call |
| 5 | Floating loss: -$9,500 | $500 | $1,000 | 50% — Stop-out |
At step 4, the broker issues a margin call warning. At step 5, the broker forcibly closes positions.
Margin Call vs. Stop-Out Levels
Most brokers use a two-tier system:
| Level | Typical Threshold | What Happens |
|---|---|---|
| Margin call | 80-100% | Warning notification — add funds or close positions |
| Stop-out | 20-50% | Broker automatically closes losing positions |
Check your broker’s specific levels. Some brokers use a single stop-out level without a prior warning, while others issue margin calls at multiple thresholds.
What Causes Margin Calls
1. Overleveraging
The most common cause. Trading too many lots for your account size leaves no room for normal price fluctuations. A $2,000 account trading 2 standard lots uses extreme leverage — any adverse move eats through margin rapidly.
2. No stop losses
Trading without stop losses means there is no cap on how much a single trade can lose. A position held through a major news event or weekend gap can move hundreds of pips against you.
3. Correlated positions
Holding long positions in EUR/USD, GBP/USD, and AUD/USD simultaneously is essentially tripling your risk in one direction. When the USD strengthens, all three positions lose simultaneously, compounding margin pressure.
4. Weekend gaps and news events
Markets can gap significantly over weekends or during major economic releases. A 100-pip gap on a position with only 50 pips of margin cushion triggers an immediate margin call at market open.
How to Avoid Margin Calls
1. Risk 1-2% per trade maximum
If every trade risks only 1-2% of your account, even a string of 10 consecutive losses reduces your account by 10-20% — painful but survivable, and nowhere near margin call territory.
2. Keep effective leverage low
Monitor your total exposure relative to your equity. Effective leverage above 10:1 puts you in the danger zone. Use the position size calculator to maintain appropriate sizing.
3. Always use stop losses
Every position should have a defined maximum loss before you enter. Stop losses ensure a single trade cannot cascade into a margin call.
4. Monitor margin level
Maintain a margin level above 300% at all times. Below 300%, your buffer against normal volatility becomes dangerously thin.
5. Avoid adding to losers
Doubling down on a losing position doubles your used margin and risk exposure. This is one of the fastest paths to a margin call.
Margin Calls in Prop Firm Trading
Prop firms have much stricter rules than standard margin calls. Most funded accounts enforce:
- 5% daily loss limit — Breach this and the account is terminated
- 10-12% overall drawdown — Total loss from starting balance or peak equity
These limits are effectively “early margin calls” designed to stop losses before they become catastrophic. Traders who monitor margin and drawdown carefully are far more likely to keep their funded accounts.
PipJournal tracks your margin usage and drawdown in real time, alerts you when you’re approaching risk limits, and helps you identify the trading patterns that lead to overleveraged positions.
