Fill or Kill Order: An order that is to be executed as soon as the order is represented in the crowd and if it cannot be executed at the limit, it is to be cancelled.
OCO Order (One cancels the other): This is a combination of two orders written on one order ticket. This instructs the floor broker that once one side of the order is filled, the remaining side of the order should be canceled. By placing both instructions on one order, rather than two separate tickets, the customer eliminates the possibility of a double fill.
