Margin Requirements: Understanding Leverage & Risk
Master margin requirements and leverage to trade safely. Learn how to avoid margin calls and protect your trading capital from forced liquidation.
What is Margin and Why Does It Matter?
Margin is the deposit required by your broker to open a leveraged position. It's not a fee or cost—it's collateral that gets "locked up" while your trade is open. Understanding margin requirements is crucial because insufficient margin leads to margin calls and potentially devastating forced liquidations.
Critical Warning
Margin calls and forced liquidations are among the top reasons traders lose money. Many traders focus on entry strategies but ignore margin management—a costly mistake that can wipe out accounts.

How to Calculate Margin Requirements
Basic Formula
Required Margin = (Trade Size × Exchange Rate) / Leverage
Example 1: Conservative Leverage
Pair: EUR/USD at 1.1000
Trade Size: 100,000 units (1 lot)
Leverage: 50:1
Account Currency: USD
Margin = (100,000 × 1.1000) / 50 = $2,200
Example 2: High Leverage
Pair: EUR/USD at 1.1000
Trade Size: 100,000 units (1 lot)
Leverage: 500:1
Account Currency: USD
Margin = (100,000 × 1.1000) / 500 = $220
Understanding Leverage Ratios
| Leverage | Margin Required | EUR/USD Example | Risk Level |
|---|---|---|---|
| 10:1 | 10% | $11,000 | Very Low |
| 30:1 | 3.33% | $3,667 | Low |
| 100:1 | 1% | $1,100 | Moderate |
| 200:1 | 0.5% | $550 | High |
| 500:1 | 0.2% | $220 | Very High |
Leverage Reality Check
Higher leverage = lower margin requirement = more buying power. But it also means higher risk. A 1% move against you with 100:1 leverage wipes out your entire margin. With 500:1 leverage, a 0.2% move can trigger a margin call.
Understanding Margin Calls
Margin Call Scenario
Account Balance: $1,000
Trade: 1 lot EUR/USD at 1.1000 with 100:1 leverage
Required Margin: $1,100
Free Margin: $1,000 - $1,100 = -$100 (Insufficient!)
Result: Trade Rejected
You cannot open this position because you don't have enough margin.
Stop-Out Scenario
Account Balance: $5,000
Trade: 1 lot EUR/USD at 1.1000 with 100:1 leverage
Required Margin: $1,100
Initial Free Margin: $3,900
Market moves against you: -300 pips ($3,000 loss)
New Account Equity: $2,000
Margin Level: $2,000 / $1,100 = 182%
Result: Approaching Danger Zone
Most brokers start margin calls at 100% margin level and force liquidation at 50%.

Safe Margin Management Practices
Rule #1: Never Use All Your Margin
Keep at least 50% of your account as free margin. This provides a buffer against adverse price movements.
Rule #2: Monitor Margin Level
Keep your margin level above 200%. This ensures you have enough buffer to withstand normal market volatility.
Rule #3: Use Lower Leverage
Professional traders often use 10:1 to 50:1 leverage, not the maximum available. Lower leverage = higher margin requirement = safer trading.

Mistake #1: Maximum Leverage Abuse
Using 500:1 leverage because it's available. High leverage amplifies both profits AND losses exponentially.
Mistake #2: Ignoring Free Margin
Opening trades without checking free margin. Always ensure you have sufficient buffer for market volatility.
Mistake #3: Multiple Correlated Positions
Opening multiple EUR/USD, GBP/USD, and AUD/USD positions. When USD moves, all positions move against you simultaneously.
