What is a fill or kill order?

A Fill or Kill (FOK) order is a time-in-force instruction that must be filled immediately and in full at the specified price, or better, or it is cancelled. It does not allow partial fills.

Some traders use fill or kill orders when they want an order to execute immediately and in full, without partial fills.
 

• Requires full execution at the specified price, or better, or the order is cancelled.
• Prevents the order from remaining in the order book if it cannot be filled immediately in full.
   

• May result in no fill if there is not enough liquidity to execute the full order size immediately at the specified price.
