Electronic Trading: Small Order Execution System (SOES)


The lack of liquidity after the 1987 market crash lead the Nasdaq to implement a mandatory system to provide automatic order execution for individual traders with orders less than or equal to 1,000 shares. (For stocks with low volume, it may be less than 200 shares). Market makers must accept small order execution system (SOES) orders and so this provides excellent liquidity for smaller investors and traders.

There are several restrictions for those who are using SOES, rather than a traditional ECN, to place their orders.

1) Trades may not be in excess of 1,000 shares for a particular stock.

2) SOES doesn't not allow trades in stocks that are trading at prices greater than $250 per share.

3) Once a trader places an order through SOES, he or she must wait at least five minutes to place a trade through SOES on the same stock.

4) Short selling through SOES must comply with SEC rules and be on a zero plus tick basis only.

5) Institutions and brokers are not allowed to place orders for their own accounts through SOES, but they can for a client's account.

6) Market makers must honor their advertised bid/ask prices to SOES orders, provided that they are for the amount that the market maker is looking for.

Initially, when SOES was mandatory, it was met with heavy pessimism from Nasdaq member firms because it forced them to execute all SOES trades that met the market maker's advertised price. There were significant limitations implemented to prevent day traders from exploiting the system and taking advantage of old prices quoted by market makers.

SOES has revamped the trading market for individual investors. It has given small investors and traders the opportunity to compete on a level playing field for access to orders and execution.
