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. Electronic markets operate different than open outcry. Check with your Linn & Associates representative if you have any questions on this.
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. This type of order is not taken in electronic markets..
