Fill Or Kill (FOK) Order

A Fill Or Kill (FOK) order is an all-or-none order instruction that requires the entire specified quantity to be filled immediately at the chosen price; if the full amount cannot be filled at once, the order is canceled.

Example: A trader places a FOK order for 8,000 shares of XYZ at a limit price of 50.00; if 8,000 shares are available to fill immediately at 50.00 or better, the order is filled; otherwise it is canceled.
