Advanced Trading: Bitcoin Fill or Kill Orders

A Fill or Kill Order (FOK) is a trade that executes immediately and entirely at a certain price, but if it cannot fill the entire order immediately, then it will be canceled entirely.

This type of order is most often used by active traders, a FOK order is most often used when trading for a large quantity of cryptocurrency. The order must be entirely filled, or it will be killed.

A fill or kill order can help ensure that a trader’s position is entered at the trader’s desired price. Using a fill or kill designation, traders can reduce the risk of a large order taking a prolonged period of time to complete. Prolonged periods of execution can cause significant changes to a cryptocurrency’s price, which can lead to unpredicted losses or gains.

Example of Fill or Kill Order

• Assume an investor wants to purchase 20 Bitcoin at a selling price of $10,000. If the investor wants to buy exactly 20 Bitcoin, and no fewer, at $10,000 (or better), a fill or kill order should be placed. If an exchange only has 10 Bitcoin selling for $10,000, then the order would be killed. If the exchange is willing to sell 20 Bitcoin but only for a price of $10,001, then the order would be killed.

• However, if the seller is      willing to sell 20 Bitcoin at $10,000, the order would be filled      immediately and completely. If the seller is willing to sell 20 Bitcoin at      a better price, say $9,999, then the order would also be filled.
