Market Basics: Margin Call & Stop Out

Margin is the cornerstone of leveraged trading. Understanding how margin calls and stop-out levels work is essential for protecting your account and managing risk effectively.

What is margin?

Margin is the portion of your account balance set aside to maintain open positions. It acts as a performance bond – not a fee – to ensure you can cover potential losses.

What is the margin level?

The margin level indicates the health of your trading account. It is displayed in %.

Margin Level = (Equity + Used margin) *100

• Equity =  Balance ± Open P&L
• Used margin =  Total margin required for all open trades.

A higher margin level means more available buffers. A lower one indicates rising risk.

What is a margin call?

A margin call is a warning that your account equity is no longer sufficient to support your open positions.

When does it happen?

When your margin Level falls to the broker’s margin call level.

What the trader typically sees:

• A platform notification or email alert
• Reduced available margin

It's recommended to either:

• Add more funds
• Reduce exposure (close some trades)
• Or tighten risk controls

A margin call does not close trades automatically – it’s a warning.

What is a stop-out level?

The stop-out level is the point where the broker automatically starts closing positions to protect your account from going negative.

When does it happen?

When your margin Level falls to the stop-out percentage.

What the platform does:

• Automatically closes the largest losing position first
• Continues closing positions until margin level rises above the stop-out threshold

This is an automated risk protection mechanism.

Margin call vs stop out: key differences

Feature	Margin Call	Stop out
Purpose	Warning	Forced Liquidation
Trigger	Margin level hits call threshold	Margin level hits the call threshold
Broker action	Alert trader	Automatically closes trades
Trader action	Add funds or reduce size	No control, once triggered

Example scenario

You open several leveraged positions requiring $500 used margin.

• Account balance: $1,000
• Equity falls to $500 due to floating losses
• Margin level = (500 ÷ 500) * 100 = 100%  → Margin Call

But losses emerge:

• Equity drops further to $250
• Margin level = (250 ÷ 500) * 100 = 50% → Stop out

The system begins closing your largest losing trades automatically.

How to avoid margin calls and stop outs

• Use appropriate position sizing
• Keep a healthy free margin buffer
• Use stop-loss orders
• Monitor correlated positions (multiple trades in related assets can increase risk exposure without you noticing)
• Add funds when necessary
• Be cautious during major news releases (as high volatility can trigger rapid margin level changes)

Proper knowledge of margin mechanics is essential for long-term trading success and will protect you from excessive losses
