A Fill or Kill (FOK) order is a type of stock market order used to execute a buy or sell instruction immediately and in its entirety. If the order cannot be completed in full at the specified price immediately, it is canceled. This ensures that the trader does not have to deal with partially filled orders or delays, allowing for precise and strategic trading.
Key Characteristics
Immediate Execution
A Fill or Kill order mandates that an order must be filled immediately. If the entire order cannot be completed promptly, it is automatically canceled. This is crucial in volatile markets where prices can change rapidly.
Total Fulfillment
The order must be executed in its entirety. Partial fulfillment is not allowed, unlike other types of orders such as “Fill and Kill” or “Immediate or Cancel” (IOC).
Use in Rapid Trading
FOK orders are often used in trading strategies where quick execution is essential to capitalize on market opportunities or mitigate risks.
Types of Trading Orders
Market Orders
Market orders are executed immediately at the current market price. They do not guarantee the price but ensure execution.
Limit Orders
Limit orders specify the maximum price to buy or minimum price to sell. They ensure a price limit but do not guarantee immediate execution.
Stop Orders
Stop orders become market orders once a specific price is reached. They are often used to limit losses.
Immediate or Cancel (IOC) Orders
Similar to FOK orders, IOC orders likewise prioritize immediate execution but allow for partial completion of the order.
Examples
-
Stock Trading: A trader might place a FOK order to buy 1,000 shares of a company at $50 per share. If 1,000 shares are not available immediately at $50, the whole order is canceled without any execution.
-
Commodities Market: An investor may use a FOK order to sell a large quantity of commodities at a particular price expecting a market movement. If the order cannot be filled swiftly, it is voided to avoid unfavorable market conditions.
