  Fill or kill is a type of order in cryptocurrency trading that requires the entire order to be executed immediately or canceled ('killed'). It is commonly used by traders who want to ensure that their order is filled quickly and completely. When a fill or kill order is placed, the exchange will attempt to execute the entire order at the specified price. If the exchange cannot fill the entire order immediately, it will cancel the remaining unfilled portion. This type of order is particularly useful in fast-moving markets where prices can change rapidly. Traders who use fill or kill orders are typically looking for immediate execution and are not willing to accept partial fills. It's important to note that not all exchanges support fill or kill orders, so it's essential to check with your exchange before placing such an order.

This means that if the exchange cannot fill the entire order at the specified price, the order will be canceled instead of being partially filled. Fill or kill orders are commonly used by traders who want to ensure quick and complete execution of their orders.
