A Fill or Kill (FOK) order is a powerful trading instruction that ensures immediate and complete execution—or no execution at all. This order type is favored by traders who prioritize speed and precision over price flexibility, especially in volatile markets like forex.
How Fill or Kill Orders Work
Fill or Kill orders operate on a simple principle:
– Full Execution Requirement: The broker must fill the entire order at the specified price immediately.
– Instant Cancellation: If full execution isn’t possible, the order is canceled entirely—no partial fills allowed.

Key Steps in FOK Execution:
- Order Submission: Trader specifies volume and target price.
- Broker Attempts Immediate Fill: The system scans liquidity pools.
- Outcome:
- Success: Trade completes at requested price.
- Failure: Order vanishes without trace.
