Price Orders
Or Better
Adding an O.B. to your order means the floor broker will only fill the order if it is trading at the fixed price or better.
Fill or Kill
This order instructs the floor broker to bid on a contract you want to buy or offer a contract you want to sell at a specified price several times and cancel it immediately if it cannot be filled at that price.
