Understanding Free Margin in Forex Trading
Free margin in forex represents the amount of funds in a trader’s account that is not tied up in open positions and is available to open new trades. It’s a vital metric that reflects your flexibility and risk buffer. Simply put, it’s the difference between your equity and the used margin. Without sufficient free margin, you won’t be able to open new positions—and worse, existing positions may be at risk of forced closure due to a margin call.
How Free Margin Fits Within Forex Margin Concepts
To fully understand free margin, you need to see how it interacts with these core concepts:
- Balance: Your account’s total value excluding current open trades.
- Equity: Your balance plus or minus any floating profits/losses from open positions.
- Used Margin: The portion of your equity that’s set aside to keep current positions open.
- Free Margin: The remaining equity after subtracting used margin.
These elements work together dynamically, shifting in real time based on market movement.
Why Free Margin Is Crucial for Forex Traders
Free margin is more than a number—it’s your margin for opportunity and protection:
- Enables new trade entries
- Buffers against market volatility
- Prevents margin calls and stop outs
Traders who monitor their free margin closely are better equipped to manage risk and seize new opportunities with confidence.
How to Calculate Free Margin in Forex
Free Margin Formula Explained
The formula is straightforward:
Free Margin = Equity – Used Margin
Where:
- Equity = Balance ± Floating P/L
- Used Margin = Sum of all margin requirements for open trades
Example: No Open Trades
- Balance: $5,000
- Equity: $5,000
- Used Margin: $0
- Free Margin = $5,000 – $0 = $5,000
Example: With Active Positions
- Balance: $5,000
- Open trade is down $500
- Equity = $4,500
- Used Margin = $1,000
- Free Margin = $4,500 – $1,000 = $3,500
Free Margin vs. Used Margin vs. Equity
| Metric | Definition | Changes With Market? |
| Used Margin | Capital allocated to open trades | No |
| Free Margin | Capital available for new trades | Yes |
| Equity | Balance + floating P/L | Yes |
Understanding these differences is key to monitoring risk and exposure.
What Happens When Free Margin Hits Zero?
Margin Call and Stop Out Explained
When your free margin reaches zero, the broker will issue a margin call, warning you to add funds or close positions. If losses continue, and your margin level falls below the stop-out threshold (often 20%–50%), the broker may automatically close positions to protect against negative balance.
How to Prevent Free Margin Depletion
- Use lower leverage
- Avoid overexposure
- Monitor trades actively
- Set stop-loss levels
