Fill or Kill (FOK)
Fill or Kill, or FOK, instructs a platform to execute the entire order immediately or cancel it. The order should not remain open or be partially filled under the instruction.
Why it matters to you
FOK is useful when a trader only wants the trade if the full requested size can be executed immediately. This distinguishes it from IOC, which can accept a partial fill.
