Forex and CFD (Contract for Difference) trading attract investors with their high leverage and flexibility. However, without proper risk management, traders risk triggering a margin call (Loss Cut)—a scenario where positions are automatically closed by the broker to prevent further losses. In extreme cases, this can lead to a blown account, wiping out all trading capital.
Understanding how margin calls work, how they’re calculated, and how to avoid them is essential for every trader. This guide breaks down the mechanics of forced liquidation, explains key calculations, and provides practical strategies to protect your trading capital.
What Is a Margin Call?
A margin call, also known as a Loss Cut, is a risk control mechanism used in Forex and CFD trading. When your account's margin maintenance ratio falls below a certain threshold set by your broker, the system automatically closes some or all of your open positions to prevent further losses.
This protects both the trader and the broker from excessive downside risk. Since Forex and CFDs use leverage, even small market movements can significantly impact your equity. While leverage amplifies potential gains, it also magnifies losses—making effective risk management crucial.
Key Purposes of a Margin Call
- Protects trading capital: Limits losses to within deposited margin.
- Prevents account blowouts: Automatically closes positions before equity hits zero.
- Maintains financial responsibility: Ensures traders don’t accumulate unmanageable debt.

How Margin Calls Work: The 20% Rule
Different brokers have different thresholds for forced liquidation. For example, many platforms—including those similar to Titan FX—set the margin call level at 20%.
When your margin maintenance ratio drops below 20%, the system triggers an automatic closure of your largest losing position(s) until the ratio returns to a safe level.
To help traders act before reaching this point, many brokers send early warning alerts when the margin ratio falls below 90%. These notifications allow you to add funds, close positions manually, or adjust your strategy before it’s too late.
How Is the Margin Maintenance Ratio Calculated?
The margin maintenance ratio determines whether your account is at risk of being liquidated. It’s calculated using the following formula:
Margin Maintenance Ratio = (Equity ÷ Used Margin) × 100%
Let’s break down the terms:
- Equity (Net Value): Your account balance plus unrealized profits or losses from open trades.
- Used Margin (Required Margin): The amount of money currently locked as collateral for open positions.
Real-World Example
Imagine you open a trade with $500 in margin, buying 1 standard lot of EUR/USD at 1.1000 with 500:1 leverage.
- Used Margin = (1.1000 × 100,000) ÷ 500 = $220
- Initial Equity = $500
- Margin Ratio = (500 ÷ 220) × 100% ≈ 227.27%
Now, suppose the price drops to 1.0954—a 46-pip loss.
- Each pip on a standard lot is worth $10 → 46 pips × $10 = $460 loss
- New Equity = $500 - $460 = $40
- Margin Ratio = (40 ÷ 220) × 100% ≈ 18.18%
Since this is below the 20% threshold, a margin call is triggered, and the position will be automatically closed.
Note: This simplified example excludes spreads and swap fees but illustrates how quickly losses can escalate under high leverage.

Risks Associated With Margin Calls
While margin calls are designed to protect traders, they come with their own risks—especially during volatile market conditions.
Risk #1: Slippage During Forced Liquidation
In fast-moving markets—such as during major news events like Non-Farm Payroll (NFP) releases—your position may be closed at a worse price than expected due to slippage. This means your actual exit price could be significantly lower (for long positions) or higher (for short positions), increasing your loss.
Risk #2: Negative Balance and Debt Liability
In extreme cases—like market gaps or flash crashes—even a forced liquidation may not prevent your account from going into negative balance. Without negative balance protection, you might owe money to the broker.
Risk Mitigation Tips
- Reduce position size before high-impact economic events.
- Monitor upcoming news using an economic calendar.
- Keep your margin level well above the liquidation threshold.
5 Proven Strategies to Avoid Margin Calls
Avoiding forced liquidation isn’t just about luck—it’s about discipline and preparation. Here are five effective methods:
1. Trade With Lower Leverage
High leverage increases profit potential but also accelerates risk. New traders should start with lower leverage (e.g., 30:1 or 50:1) to build experience without exposing themselves to sudden blowouts.
2. Always Set Stop-Loss Orders
A stop-loss order acts as your first line of defense. By setting it at a strategic level, you exit losing trades before they trigger a margin call. This gives you control over your risk rather than leaving it to automated systems.
3. Use Partial Closures to Manage Pressure
If your margin ratio is approaching danger levels, consider closing part of your position. This reduces used margin and improves your ratio, giving you breathing room while keeping some exposure to potential reversals.
4. Add Funds Before It’s Too Late
Depositing additional capital (topping up) can instantly boost your margin ratio. This is useful if you believe the market will recover but need time. Just be cautious not to overcommit in a losing trade.
5. Choose Brokers With Smart Risk Controls
Look for platforms that offer:
- Early warning alerts (e.g., at 90% margin usage)
- Negative balance protection
- Transparent margin calculation tools
These features give you more time and control to respond proactively.
Frequently Asked Questions (FAQ)
Q1: Is a higher or lower margin call level better?
| Level | Pros | Cons |
|---|---|---|
| High (e.g., 80–100%) | Limits risk early; protects beginners | May close trades prematurely on minor dips |
| Low (e.g., 20%) | Gives room for volatility; suits experienced traders | Higher chance of large drawdowns |
A 20% threshold offers experienced traders more flexibility while still providing protection.
Q2: What’s the difference between a stop-loss and a margin call?
| Feature | Stop-Loss | Margin Call |
|---|---|---|
| Control | Set by trader | Triggered by broker |
| Purpose | Limit loss per trade | Protect overall account |
| Timing | Price-based | Equity-to-margin ratio based |
| Flexibility | Fully customizable | Fixed by broker rules |
Always use stop-losses proactively—they help you stay ahead of margin calls.
Q3: How are margin calls and blown accounts related?
A margin call aims to prevent a blown account by closing positions before equity vanishes. But during rapid market moves, slippage or gapping can cause losses to exceed available funds—resulting in a negative balance even after liquidation.
Proper position sizing and stop-loss usage are critical to breaking this chain.
Final Thoughts: Risk Management Is Non-Negotiable
A margin call isn’t just a technical event—it’s a warning sign that risk controls have failed. While platforms provide automated safeguards like 20% liquidation rules and early alerts, relying solely on them is dangerous.
Successful trading requires proactive discipline:
- Use conservative leverage
- Set stop-losses on every trade
- Monitor your margin level daily
- Prepare for volatility around major news
By combining smart strategies with reliable tools, you can navigate leveraged markets safely and sustainably.
