Free Margin

Free margin is the equity not locked by open positions - the amount available to open new trades or absorb losses.

Quick answer

Free margin is equity not locked by open positions, available for new trades and to absorb losses. When it runs out, you cannot open positions and stop-out is near.

Definition

Free margin is the portion of account equity not tied up as margin by open positions. It is the buffer that absorbs floating losses before a margin call, and the amount available to open new positions. Free margin falls as positions move against you and as you open new trades. When free margin hits zero, you cannot open further positions, and if margin level keeps falling to the stop-out point, the broker closes positions.

How It Works

  • Free margin = equity - used margin
  • Shrinks with floating losses and new positions
  • Zero free margin blocks new orders

Trading Tips

1

Keep free margin for the worst-case move, not just the current price

2

Opening to the maximum margin is the fastest route to a stop-out

3

Free margin is per-account: hedging across pairs still consumes it
