Enter and Cancel Order:
All orders, except Market Orders, can be cancelled and replaced with a different order unless filled prior to cancellation.
Fill or Kill Order:
The fill or kill order is used by customers wishing an immediate fill, but at a specified price. The floor broker will bid or offer the order three times and immediately return either a fill or an unable.
Good Until Cancelled Order:
Used in conjunction with a Limit or Stop order. Order will remain valid and worked until client cancels order, or it is filled, or contract expires.
The limit order is an order to buy or sell at a designated price. Limit Orders to buy are placed below the market while limit orders to sell are placed above the market. Since the market may never get high enough or low enough to trigger a limit order, a customer may miss the market if he uses a limit order. (Even though you may see the market touch a limit price several times, this does not guarantee or earn the customer a fill at that price.)
Market If Touched Order:
MITs are the opposite of stop orders. Buy MITs are placed below the market and Sell MITs are placed above the market. An MIT order is usually used to enter the market or initiate a trade. An MIT order is similar to a limit order in that a specific price is placed on the order. However, an MIT order becomes a market order once the limit price is touched or passed through. An execution may be at, above, or below the originally specified price. An MIT order will not be executed if the market fails to touch the MIT specified price.
The market order is the most frequently used order. It is the best order to use once you have made a decision about opening or closing a position. It prevents the customer from having to chase a market or trying to get in or out of a position. The market order is executed at the best possible price obtainable at the time the order reaches the trading pit.
Market on Close:
This is an order that will be filled during the final seconds of trading at whatever price is available.
Market on Opening Order:
This is an order that the client wishes to be executed during the opening range of trading at the best possible price obtainable within the opening range. Not all exchanges recognize this type of order. One such exchange is the Chicago Board of Trade.
One Cancels the Other Order (OCO) - One (order) Cancels (the) Other:
As an example, with the market trading at 7800 you want to buy at 7600 Limit (lower), or on an upside breakout at 7900 Stop (higher), Buy 1 Dec DJIA 7600 on a Limit, OCO Buy 1 Dec DJIA 7900 Stop. When one order is executed, the other is automatically cancelled.
Or Better Order:
The pit broker is obligated to get the best possible price for the client. Putting an OB on an order does not cause him to work harder. If the price is NOT OB, the broker is irate because he is paying special attention to a ticket that does not deserve it. Think of OB as MARKET with a LIMIT. If the price does not have an OB next to it, and the market is considerably better, the pit broker may question the runner to see if the order should have been a stop. They will return the order for clarification which could delay the filling of the order and possibly change the results of the fill. ONLY USE "OR BETTER" IF THE MARKET IS "OR BETTER."
Stop Limit Order:
A stop limit order lists two prices and is an attempt to gain more control over the price at which your stop is filled. The first part of the order is written like the above stop order. The second part of the order specifies a limit price. This indicates that once your stop is triggered, you do not wish to be filled beyond the limit price. Stop limit orders should usually not be used when trying to exit a position. If a customer does not give a limit price, then the stop price and the limit price are meant to be identical.
The customer wishes to take a simultaneous long and short position in an attempt to profit via the price differential or "spread" between two prices. A spread may be established between different months of the same commodity, between related commodities or between the same or related commodities traded on two different exchanges. A spread order may be entered at the market or you can designate that you wish to be filled when the price difference between the commodities reaches a certain point (or premium). For example: BUY 1 JUNE LIVE CATTLE, SELL 1 AUGUST LIVE CATTLE PLUS 100 TO THE AUGUST SELL SIDE. This means that the customer wants to initiate or liquidate the spread when August Cattle is 100 points higher than June cattle.
Stop orders may be used for three purposes: to minimize a loss on a long or short position; to protect a profit on an existing long or short position; or to initiate a new long or short position. A buy stop order is placed above the market and a sell stop order is placed below the market. Once the stop price is touched, the order is treated like a market order and will be filled at the best possible price.
Stop Close Order:
The stop price on a stop close only will only be triggered if the market touches the stop during the close of trading. The disadvantage of this order is a fast market in the last few minutes of trading may cause the order to be filled at an undesirable price. It could, however, protect the customer from getting filled during adverse price fluctuations during the course of the day.
