Short answer
Margin calls are based on equity, not balance. Even if your balance is positive, floating losses can reduce equity to critical levels and trigger a margin call.
What balance really means
Balance is:
- closed trade result
- money after profits and losses are finalized
- does not change while trades are open
It reflects your account history — not current risk.
What equity actually represents
Equity is:
Balance + floating profit/loss
It changes constantly with market movement.
When trades go against you:
- floating loss increases
- equity decreases
This is what the system monitors for risk.
Why margin calls are triggered by equity
Margin call happens when:
- equity drops too close to required margin
- risk becomes too high
Even with positive balance:
👉 falling equity can still trigger margin call
Simple example
You may have:
- Balance: $5,000
- Floating loss: -$4,000
- Equity: $1,000
Your balance looks fine — but your equity is almost gone.
This is when margin call appears.
The illustration shows how floating loss reduces equity while balance remains unchanged.
Why this is normal risk control
This is not:
❌ platform error
❌ broker interference
❌ money disappearing
This is:
✅ automatic risk protection
✅ standard trading safety system
✅ used by all leveraged markets
Why this matters for traders
Understanding equity vs balance helps traders:
- avoid surprise margin calls
- manage position size
- use leverage safely
- monitor real risk
Most margin problems come from watching balance instead of equity.
