Margin Call Explained: How to Avoid and Survive It
Understand what causes margin calls, how to prevent them, and what to do if you face one in forex trading

What is a Margin Call?
A margin call is a broker's demand for you to deposit more funds or close positions because your account equity has fallen below the required margin level.
In simpler terms: You're running out of money to keep your trades open.
If you don't respond to a margin call, the broker will automatically close your positions (liquidation) to protect themselves from your account going negative.
How Margin Trading Works
Key Terms You Must Know
| Term | Definition | |------|------------| | Balance | Your account balance (deposits - withdrawals ± closed trades) | | Equity | Balance + floating P/L (what you'd have if you closed all positions) | | Used Margin | Funds locked as collateral for open positions | | Free Margin | Equity - Used Margin (funds available for new trades) | | Margin Level | (Equity / Used Margin) × 100% |
The Margin Level Formula
Margin Level = (Equity / Used Margin) × 100%
Example:
- Equity: $5,000
- Used Margin: $1,000
- Margin Level: ($5,000 / $1,000) × 100 = 500%
When Does a Margin Call Occur?
Most brokers trigger margin calls at specific margin levels:
| Margin Level | What Happens | |--------------|--------------| | Above 100% | Normal trading | | 100% | Margin call warning | | 50-80% | Margin call (varies by broker) | | 20-50% | Stop out / Liquidation |
Example Margin Call Scenario
Starting:
- Account Balance: $10,000
- Open Position: 1 lot EUR/USD
- Used Margin: $2,000
- Equity: $10,000
- Margin Level: 500%
Price moves against you by 400 pips:
- Floating Loss: $4,000
- Equity: $10,000 - $4,000 = $6,000
- Margin Level: ($6,000 / $2,000) × 100 = 300%
Price moves another 350 pips against:
- Floating Loss: $7,500
- Equity: $2,500
- Margin Level: 125% → WARNING
Price moves further:
- Floating Loss: $8,000
- Equity: $2,000
- Margin Level: 100% → MARGIN CALL!
Why Margin Calls Happen
Reason 1: Overleveraging
The #1 cause. Trading too large relative to your account.
Example of overleveraging:
- $5,000 account
- Trading 2 lots (200,000 units)
- This is 40:1 leverage
- A 2.5% adverse move = account wiped
Reason 2: No Stop Loss
Holding a losing position hoping it "comes back" without a stop loss.
Reason 3: Gap Risk
Markets can gap over weekends. Your stop loss won't protect you from gaps.
Reason 4: Adding to Losing Positions
"Averaging down" or "doubling down" on losers increases exposure to a trade that's already proving you wrong.
Reason 5: Correlated Positions
Holding multiple positions that move together (e.g., long EUR/USD and GBP/USD) multiplies your risk without you realizing.
How to Avoid Margin Calls
Strategy 1: Proper Position Sizing
Use our Lot Size Calculator to determine the correct position size based on:
- Your account balance
- Your risk per trade (1-2%)
- Your stop loss distance
Rule of thumb: Never risk more than 2% of your account on a single trade.
Strategy 2: Always Use Stop Losses
Every trade needs a stop loss. Period.
- Set it at a logical technical level
- Size your position so the stop loss = 1-2% max loss
- NEVER remove or widen a stop loss
Strategy 3: Monitor Your Margin Level
Keep your margin level above 500% at all times:
| Margin Level | Status | |--------------|--------| | Above 500% | Safe zone | | 200-500% | Caution | | 100-200% | Danger zone | | Below 100% | Critical - reduce positions immediately |
Strategy 4: Limit Leverage
Just because your broker offers 500:1 leverage doesn't mean you should use it.
Recommended maximum leverage:
| Trader Type | Max Leverage | |-------------|--------------| | Beginner | 10:1 | | Intermediate | 20:1 | | Advanced | 50:1 | | Prop Firm | Per firm rules |
Strategy 5: Diversify Properly
Don't load up on correlated pairs:
| Highly Correlated | Lower Correlation | |-------------------|-------------------| | EUR/USD + GBP/USD | EUR/USD + USD/JPY | | AUD/USD + NZD/USD | GBP/USD + EUR/JPY |
Strategy 6: Keep Reserve Funds
Don't use your entire account for trading. Keep 30-50% as reserve margin.
What to Do If You Get a Margin Call
Option 1: Deposit More Funds
If you believe in your positions and have additional capital, you can:
- Deposit funds quickly
- This increases equity
- Margin level improves
⚠️ Warning: This is often throwing good money after bad. Only do this if you have a very strong conviction.
Option 2: Close Positions
The safer option:
- Close the worst-performing position
- Or close all positions
- Accept the loss and live to trade another day
Option 3: Reduce Position Size
If you can't close everything:
- Close part of your position
- This frees up margin
- Gives your trade more room
Margin Call Calculation Examples
Example 1: EUR/USD Trade
Setup:
- Account: $10,000
- Trade: 1 lot EUR/USD
- Margin requirement: 3.33% (30:1 leverage)
- Used margin: $3,330
How far can price move before margin call (at 100% level)?
Available equity for loss = $10,000 - $3,330 = $6,670
Pip value per lot = $10
Max pip movement = $6,670 / $10 = 667 pips
The price can move 667 pips against you before margin call.
Example 2: Gold (XAU/USD) Trade
Setup:
- Account: $5,000
- Trade: 0.5 lots Gold
- Current price: $2,000
- Margin requirement: 5%
- Used margin: $5,000 × 5% = $250
Note: Gold is volatile! A $50 move in gold = 500 pips = $250 profit/loss per 0.5 lot.

Margin Levels by Broker Type
| Broker Type | Margin Call Level | Stop Out Level | |-------------|-------------------|----------------| | US Brokers | 100% | 25% | | EU Brokers | 100% | 50% | | Australian | 80% | 50% | | Offshore | Varies | As low as 20% |
Prop Firm Considerations
Prop firms like FTMO, Funded Next, and The5ers have additional rules:
- Daily drawdown limits (typically 4-5%)
- Maximum drawdown (typically 8-10%)
- These are stricter than margin calls
You'll hit these limits long before a traditional margin call. Calculate your position sizes accordingly.
Frequently Asked Questions
Can I owe money if I get margin called?
In most cases, no. Brokers close positions before your account goes negative. However, in extreme volatility (like SNB 2015), gaps can cause negative balances.
Many brokers now offer negative balance protection.
What's the difference between margin call and stop out?
- Margin call = Warning that you're running low on margin
- Stop out = Broker forcibly closes your positions
How do I calculate margin requirement?
Margin = (Contract Size × Price) / Leverage
Example: 1 lot EUR/USD at 1.0850 with 30:1 leverage = (100,000 × 1.0850) / 30 = $3,617
Is it possible to trade profitably with high leverage?
Possible? Yes. Sustainable? Rarely.
High leverage amplifies both wins AND losses. Most successful traders use conservative leverage.
