What is “Margin Call Level” or a “Margin Call”?

In forex trading, the Margin Call Level refers to a specific percentage threshold that your Margin Level must stay above. If your Margin Level falls to or below this point, it triggers a Margin Call—a warning that your account is in trouble.

Think of it like a warning light flashing on your dashboard—your account doesn’t have enough equity to safely support your open trades.

Margin Call Level vs. Margin Call (What’s the Difference?)

This trips up a lot of traders, so let’s break it down:

  • Margin Call Level: A predefined value, such as 100%, set by your broker. When your Margin Level falls to this point, you’ll receive a warning.
  • Margin Call: The actual event that occurs when your Margin Level hits that threshold—usually a notification (email, message, or alert).

🔥 Analogy: Boiling Water

  • Margin Level = Temperature
  • Margin Call Level = 100°C (the boiling point)
  • Margin Call = The water boiling (the event)

How is a Margin Call Triggered?

A Margin Call happens when:

Floating losses reduce your Equity to the point where it’s equal to or less than your Used Margin.

In other words:

Margin Level = (Equity ÷ Used Margin) × 100%
If this drops to 100% (or the broker’s set level), you’ll get a Margin Call.

Example: Margin Call at 100%

Let’s say your broker has a Margin Call Level of 100%.

Account Setup:

  • Balance: $1,000
  • You open a EUR/USD trade (1 mini lot = 10,000 units)
  • Required Margin: $200
  • Since there’s only one open trade, Used Margin = $200

Now, your trade goes south—you’re down 800 pips, or $800.

Step 1: Calculate Equity

Equity = Balance + Floating P/L = $1,000 – $800 = $200

Step 2: Calculate Margin Level

Margin Level = ($200 ÷ $200) × 100% = 100%

You’ve hit the Margin Call Level.

What Happens Next?

Once your Margin Level hits 100%:

  • ❌ You can’t open new trades
  • ✅ You can only close existing trades
  • ⚠️ You’ll receive a notification from your broker (aka the Margin Call)

To continue trading, you’ll need to either:

  1. Deposit more funds to increase Equity
  2. Close some trades to reduce Used Margin
  3. Hope the market reverses in your favor and reduces floating losses

But What If Things Get Worse?

If your losing position keeps bleeding and your Margin Level drops below 100%, you’re not just in trouble—you’re in danger of a Stop Out.

A Stop Out Level is a lower threshold (like 50% or 20%, depending on the broker). Once reached, your broker will begin automatically closing your trades to protect itself.

Think of it this way:

  • Margin Call = Warning
  • Stop Out = Emergency action

⚠️ Boiling Water Analogy (Part 2)

  • Margin Call = Water starts boiling
  • Stop Out = You get burned

Recap

  • Margin Call Level is the threshold that triggers a Margin Call (usually set at 100% Margin Level)
  • Margin Call is the event when your Equity is equal to or less than your Used Margin
  • When your Margin Level hits 100%, you can’t open new trades
  • If the trade continues to lose money, you may hit the Stop Out Level, and your broker will begin closing trades automatically
