Remember, options can be shorted. One can buy to open or to close. Likewise, one can sell to open or to close. If your order has any restrictions, place them here at the end. Remember, restricted order have no standing.
Unrestricted orders have execution priority.
Finally, state if the order is a day order or Good Till Canceled. If you don't say, the broker will assume it to be a day order only, but the client should mention it as a courtesy. If you don't catch an error at this point, they can stick you with the trade. Proper order entry can mean the difference between a successful execution and a missed fill or a poor price. Doing it the right way can save you precious seconds.
