• FILL OR KILL ORDER (FOK)
  
  A trading order that is canceled unless executed within a designated time period. A market or limited price order that is to be executed in its entirety as soon as it is represented in the trading crowd, and, if not so executed, is to be treated as canceled. For purposes of this definition, a stop is considered an execution. Equivalent to AON and IOC simultaneously.
