Answer: Fill or kill order
Step-by-step explanation:
A fill or kill order is used when an individual or firm wants to either buy or sell a stock and in such cases, the order must be done as quickly as possible in its entirety.
If the order isn't done immediately at the price that has been specified or a price that's more than the specified price, such order is cancelled. Also, for a fill or kill order, partial execution isn't applicable.
