TL;DR — A margin call is a warning that your margin level percent has fallen to a broker-set threshold, while a stop out is when the broker automatically closes positions to prevent your account from going negative. Understanding margin call vs stop out helps you manage risk and avoid forced liquidation.
What Margin Level Percent Really Means
Margin level percent is the ratio of your account equity to the margin currently required for your open positions, expressed as a percentage. It tells you how much breathing room you have before the broker steps in. The formula is:
Margin Level = (Equity / Used Margin) × 100
Equity is your account balance plus or minus floating profit or loss. Used margin is the total margin tied up by open trades. If you have no open positions, margin level is not defined (often shown as 0% or blank).
For example, suppose you have a $10,000 account and open one standard lot of EUR/USD with a 1% margin requirement. The used margin is $1,000. If the trade is down $500, equity becomes $9,500, and margin level is ($9,500 / $1,000) × 100 = 950%. That is comfortable. But if the trade loses $8,000, equity drops to $2,000, and margin level falls to 200%. As losses grow, margin level shrinks.
Margin Call: The Warning Shot
A margin call occurs when your margin level hits a predetermined threshold, commonly 100% at many brokers, though it can be lower or higher. At this point, the broker notifies you that your account is at risk. In practice, the "call" is usually an automated alert, not a phone call from a human.
What does it mean? Your equity has fallen to the point where it equals your used margin. You cannot open new positions, and if the market moves further against you, the broker will take action. A margin call is not a penalty; it is a risk management signal. It gives you a chance to deposit more funds, reduce position size, or close trades before things get worse.
Many traders ignore margin calls, hoping the market will turn. That is dangerous. The margin call is the last clear warning before the stop out.
Stop Out: When Positions Are Closed
A stop out is the broker's automatic closure of your positions when your margin level falls to a second, lower threshold, often 50% or 20% (varies by broker and account type). The broker does this to protect itself and you from a negative balance. Once the stop out level is breached, the broker begins closing your largest losing positions first, continuing until your margin level is back above the stop out threshold.
Stop out is not a suggestion; it is enforced. You cannot prevent it once triggered, and you may not get the exact price you wanted, especially in fast markets. The closure happens at market price, which can lead to slippage.
Understanding the difference between margin call and stop out is crucial: the margin call is a warning, the stop out is the execution.
Worked Example: From Margin Call to Stop Out
Let's walk through a realistic scenario with numbers.
- Account balance: $5,000
- Open position: 1 standard lot of XAUUSD (gold), contract size 100 oz
- Margin requirement: 1% of notional value
- Gold price at entry: $2,000 per oz
- Notional value: 100 oz × $2,000 = $200,000
- Used margin: 1% × $200,000 = $2,000
- Free margin: $5,000 - $2,000 = $3,000
Now suppose gold falls to $1,970, a $30 drop. Your loss is 100 oz × $30 = $3,000. Equity becomes $5,000 - $3,000 = $2,000. Margin level = ($2,000 / $2,000) × 100 = 100%. This triggers a margin call if your broker's threshold is 100%.
If gold continues to $1,950, your loss increases to $5,000. Equity is now $0, and margin level is 0%. But most brokers would have already stopped out before this point. For instance, with a 50% stop out level, the broker would close the position when margin level hits 50%, which occurs when equity = 0.5 × $2,000 = $1,000. That means a loss of $4,000, corresponding to gold at $1,960. At that price, the broker closes the position, leaving you with $1,000 equity.
This example shows how quickly losses can escalate with leveraged gold. A 2% drop in gold price wiped out 80% of the account.
How to Avoid Forced Liquidation
Prevention is better than cure. Here are practical steps to keep your margin level healthy:
- Use lower leverage. Higher leverage magnifies both profits and losses, and reduces your margin level faster.
- Monitor margin level daily. Don't wait for a margin call; check your account regularly, especially during volatile news events.
- Set stop-loss orders. A stop-loss automatically closes a losing trade at a predetermined level, preventing it from dragging your margin level down.
- Diversify. Avoid concentrating all your margin in one trade or one asset class. Correlated positions can all move against you simultaneously.
- Keep a cash buffer. Don't use all your free margin. A buffer gives you room to absorb drawdowns without hitting thresholds.
- Understand your broker's thresholds. Margin call and stop out levels vary. Check your account specifications on your broker's website or in your trading platform.
Additionally, consider the impact of trading costs on your margin. Every trade incurs spreads and commissions, which reduce your equity. A per-lot rebate from a service like Expaid can lower your overall cost, giving you slightly more breathing room. While it won't prevent a margin call on its own, reducing costs is a step toward better risk management. You can estimate potential savings with our rebate calculator.
In our view — The best defense against margin calls is not more capital but smaller positions. Traders often focus on entry and exit signals while ignoring position sizing, yet sizing determines whether a normal market fluctuation becomes a catastrophe. Treat margin level as a live risk gauge, not an afterthought.
Margin Call vs Stop Out: Key Differences
| Feature | Margin Call | Stop Out |
|---|---|---|
| Trigger | Margin level falls to warning threshold (e.g., 100%) | Margin level falls to liquidation threshold (e.g., 50%) |
| Action | Notification; no automatic closure | Automatic closure of positions |
| Purpose | Alert trader to add funds or reduce risk | Protect broker and trader from negative balance |
| Trader control | Can deposit, close trades, or hedge | No control; broker liquidates at market |
| Consequence | Chance to avoid further losses | Realized losses; potential slippage |
Knowing these differences helps you act decisively when a margin call appears.
