Fill Or Kill Order (FOK)

Fill Or Kill Order (FOK) is a trade order used in both crypto and fiat exchanges. It mandates the immediate execution of the entire order quantity at a specified price. If the entire order cannot be filled instantly, it is canceled entirely. This order type ensures that traders either execute the whole transaction immediately or do not execute it at all. FOK orders are useful in volatile markets where quick decisions are necessary and partial order execution could lead to unintended market exposure or price fluctuations.
