What is a margin call and how can I avoid it?

A margin call occurs when your margin level drops below 100%, meaning your losses have eroded your account to the point where you don't have enough equity to maintain your open positions. Brokers will automatically close your positions to prevent negative balance. To avoid margin calls: keep margin level above 200%, never use maximum leverage, don't overtrade, use proper stop losses, and maintain a cash buffer in your account.

What leverage should beginners use?

Beginners should use low leverage of 1:10 to 1:30 maximum. While brokers offer 1:500 or higher, high leverage amplifies both gains and losses dramatically. A 1% adverse move with 1:100 leverage means a 100% account loss. Start with 1:10 leverage to learn proper risk management. As you gain experience and consistency, you can gradually increase leverage, but most professional traders rarely use more than 1:50.

How much free margin should I keep available?

Always keep at least 50% of your account as free margin. Never use 100% of your available margin even if the calculator says you can. Markets can move against you quickly, and you need buffer room to absorb temporary losses without getting margin called. Professional traders often keep 70-80% free margin to ensure they can weather volatility and add to winning positions if needed.

What's the difference between margin and leverage?

Margin is the actual money required to open a position (collateral), while leverage is the ratio that determines how much you can control. For example, with 1:100 leverage, you need $1,000 margin to control a $100,000 position. Higher leverage means less margin required, but it doesn't change your risk - you can still lose the same amount. Leverage is a tool; margin is the cost of using that tool.

Is it safe to use high leverage if I use small position sizes?

This is a common misconception. Leverage itself doesn't determine risk - position size does. You can use 1:500 leverage with tiny positions and be safer than using 1:10 leverage with huge positions. However, high leverage is psychologically dangerous because it makes overtrading easy. It's better to use moderate leverage (1:20 to 1:50) and consciously control position sizes based on your risk management rules rather than relying on willpower with high leverage available.

What happens to my margin level when trades move against me?

When trades move against you, your equity decreases (account balance minus losses), but your used margin stays the same. This causes your margin level to drop. For example, if you have $10,000 equity and $5,000 used margin (200% margin level), and you lose $2,500, your equity becomes $7,500 but used margin is still $5,000, dropping your margin level to 150%. If losses continue and margin level hits 100% or below, you risk a margin call.

Understanding Margin & Leverage

Margin

Margin is the amount of money required to open and maintain a leveraged position. It acts as a good faith deposit with your broker.

Leverage

Leverage allows you to control a large position with a small amount of capital. For example, 1:100 leverage means you can control $100,000 with just $1,000.

Free Margin

The amount of money available to open new positions. It's your equity minus used margin.

Margin Level

A percentage showing the health of your account. Below 100% may trigger a margin call. Above 200% is considered healthy.

Formula Breakdown

Required Margin

Required Margin = Trade Size / Leverage

The amount of capital needed to open a position based on your leverage ratio.

Free Margin

Free Margin = Equity - Used Margin

Available funds to open new positions or absorb losses.

Margin Level

Margin Level = (Equity / Used Margin) × 100%

Percentage indicating account health and risk of margin call.

Used Margin

Used Margin = Sum of all open positions' margins

Total margin locked up in all your current open trades.

Example 1: Conservative Leverage (1:100)

Scenario: Standard leverage with moderate position

• Trade Size: $100,000 (1 standard lot EUR/USD)

• Leverage: 1:100

• Account Balance: $10,000

• Already Used Margin: $0

Results:

Required Margin: $100,000 / 100 = $1,000

Free Margin: $10,000 - $1,000 = $9,000

Margin Level: ($10,000 / $1,000) × 100 = 1,000%

✓ Very Healthy - Plenty of room for additional trades

Example 2: High Leverage (1:500)

Scenario: High leverage with multiple positions

• Trade Size: $250,000 (2.5 standard lots)

• Leverage: 1:500

• Account Balance: $5,000

• Already Used Margin: $2,000

Results:

Required Margin: $250,000 / 500 = $500

Total Used: $500 + $2,000 = $2,500

Free Margin: $5,000 - $2,500 = $2,500

Margin Level: ($5,000 / $2,500) × 100 = 200%

⚠ Caution - At minimum healthy level, avoid more positions

Leverage Warnings & Best Practices

High Leverage = High Risk

While 1:500 leverage requires less margin, it amplifies both gains AND losses. A small adverse move can wipe out your account.

Margin Call Risk

If your margin level drops below 100%, brokers may close your positions automatically to prevent negative balance.

Use Lower Leverage

Professional traders often use 1:10 to 1:50 leverage. Just because 1:500 is available doesn't mean you should use it.

Monitor Margin Level

Always keep your margin level above 200%. This gives you buffer room for market fluctuations.

Don't Overtrade

Having free margin doesn't mean you should open more positions. Stick to your trading plan and risk management rules.

Keep Emergency Buffer

Never use 100% of your account. Keep at least 50% as a safety buffer for unexpected market moves.
