Limit-on-Open Order

In trading, a limit-on-open (LOO) order is a type of order made by an investor to a broker. This order requests that the broker buy or sell specified securities if the price is equal or better than a specified limit price when an exchange opens. If the price of a share is not equal or more favorable than the limit price at the time that the exchange opens, the order is canceled.
