What is Margin in Forex Trading

Margin is the money you need to deposit to open and maintain leveraged positions. It's not a fee or cost—it's collateral that your broker holds while your trade is open. Understanding margin prevents unexpected position closures.

Margin Explained Simply

When you use leverage, you're essentially borrowing money from your broker. Margin is the "good faith deposit" that secures this loan.

Example:

You want to trade $100,000 (1 standard lot)
Your broker requires 1% margin
You need $1,000 in your account to open this trade
That $1,000 is your margin—it's locked until you close the trade

Types of Margin

Required Margin (Used Margin)

The amount locked up for your open positions:

Required Margin = Position Size ÷ Leverage

With 1:100 leverage and $50,000 position:

$50,000 ÷ 100 = $500 required margin

Free Margin

Money available to open new trades or absorb losses:

Free Margin = Equity - Used Margin

If your equity is $5,000 and used margin is $1,000:

Free Margin = $5,000 - $1,000 = $4,000

Equity

Your account balance adjusted for open trade profits or losses:

Equity = Balance + Floating Profit/Loss

Margin Level

A percentage showing your account health:

Margin Level = (Equity ÷ Used Margin) × 100

Brokers use this to determine if you're at risk of a margin call.

Understanding Margin Level

Margin Level	Status
Above 200%	Healthy—room to trade
150-200%	Caution—monitor closely
100-150%	Warning—reduce exposure
Below 100%	Danger—margin call territory
50% or below	Stop out—positions closed

Example:

Equity: $3,000
Used Margin: $2,000
Margin Level: ($3,000 ÷ $2,000) × 100 = 150%

You're in the caution zone—a losing trade could trigger problems.

What is a Margin Call?

A margin call occurs when your margin level drops below the broker's minimum requirement (often 100%). It's a warning that you need to:

Deposit more funds, or
Close some positions

If you don't act, the broker will automatically close your positions to protect themselves from further losses.

What is Stop Out Level?

The stop out level is when brokers automatically close your positions. This typically happens at 50% margin level, though it varies by broker.

How it works:

Your margin level hits 50%
Broker closes your largest losing position
This frees up margin and increases your margin level
If still below 50%, another position closes
Process continues until margin level recovers

This protects you from going into negative balance, but you'll realize losses on closed positions.

Margin Calculation Example

Setup:

Account Balance: $10,000
Leverage: 1:100
Trade: Buy 1 standard lot EUR/USD at 1.1000

Calculations:

Position Value: $110,000 (100,000 × 1.1000)
Required Margin: $1,100 (1% of position)
Free Margin: $8,900 ($10,000 - $1,100)
Margin Level: 909% ($10,000 ÷ $1,100 × 100)

If the trade loses 500 pips ($5,000):

Equity: $5,000
Used Margin: $1,100
Free Margin: $3,900
Margin Level: 454%

Still safe, but significantly reduced.

How to Avoid Margin Calls

Use Appropriate Position Sizes: Risk 1% per trade, and a fixed 0.5% through your first year of live trading.

Monitor Margin Level: Keep it above 200% for safety.

Set Stop Losses: Limit losses before they threaten your margin.

Don't Overtrade: Multiple open positions multiply margin requirements.

Keep Reserve Capital: Don't use all available margin.

Understand Your Broker's Levels: Know the margin call and stop out percentages.

Margin Requirements by Pair Type

Different pairs may have different margin requirements:

Pair Type	Typical Margin	Leverage
Major Pairs	0.5-3.3%	1:30-1:200
Minor Pairs	1-5%	1:20-1:100
Exotic Pairs	3-10%	1:10-1:33

Exotic pairs require more margin due to higher volatility.

Check the licensed entity that will hold your account on the regulator's public register.
