automated order entry system (business) (AOES)

An Automated Order Entry System (AOES) is a computer system that routes order executions on the stock exchange directly to the specialists in stock exchange trading.

With the AOES system, the traditional brokers, the floor brokers, do not intervene in trading at any time. By using an Automated Order Entry System, order execution can be significantly accelerated and streamlined. It is mainly used for smaller orders. Examples are the Designated Order Turnaround System (DOT) of the New York Stock Exchange or the Small Order Execution System (SOES) at NASDAQ.
