Fill or Kill - FOK
An order to fill a transaction immediately and completely or not at all.
Investopedia Commentary
This type of order is usually for a large quantity of stock, and must be filled in its entirety or canceled (killed). Examples include market and limit orders requiring immediate executing. In reality, the fill-or-kill type of trade does not occur very often.
