What Is Free Margin?
Free margin is the amount of your account equity that isn’t currently tied up as margin for open positions, available for opening new trades or absorbing further unrealized losses.
This connects directly to the leverage and margin concepts covered in FXM680’s guide on how forex leverage works, since margin usage directly determines how much free margin remains.
How Free Margin Is Calculated
Free margin is generally calculated as your account equity, meaning balance adjusted for any open position’s floating profit or loss, minus the margin currently committed to open positions.
As open positions move in your favor, free margin typically increases, while positions moving against you reduce it.
| Term | What It Represents |
|---|---|
| Equity | Balance adjusted for floating profit or loss |
| Used margin | Capital committed to open positions |
| Free margin | Equity minus used margin |
Why Free Margin Changes Constantly
Since equity fluctuates with live market prices, free margin shifts continuously while positions remain open, even without placing any new trades.
Opening additional positions reduces free margin further, since more capital becomes committed as used margin.
Why This Figure Deserves Attention
Monitoring free margin helps you understand how much room remains before your account approaches more restrictive territory, connecting to concepts covered elsewhere in the Forex Academy around margin level and stop-out thresholds.
A shrinking free margin figure, especially during volatile periods, is often an early signal worth acting on before conditions worsen further.
Frequently Asked Questions
Does free margin include unrealized profit from open positions?
Yes, since it’s based on equity, which reflects floating profit or loss on open positions.
Can free margin go negative?
Generally, brokers intervene through mechanisms like stop-out levels before free margin reaches zero, though this varies by broker.
Should I check free margin before every new trade?
It’s a good habit, since it tells you how much room you genuinely have before committing to another position.
