Electronic Trading: Conclusion

If you are a long-term investor, you can take this tutorial with a grain of salt. At least now you have some insight into how electronic systems give direct access to the market. We hope this has enlightened your outlook and helped you achieve a greater understanding of how the execution of stock orders is done. For those who are looking to become a trader, this is the tip of the iceberg and we'd advise you to do a lot more research in this area before jumping in.

Let's recap what we have learned:

•The NYSE is an auction market and uses specialists to trade securities.
•The Nasdaq is an OTC market where trading is facilitated through market makers.
•Each stock listed on the NYSE is allocated to a specialist who matches up buyers and sellers, provides liquidity and finds the fair price at the beginning of each trading day.
•A market maker provides continuous bid and offer prices within a prescribed percentage spread for shares in which they are designated to make a market.
•SuperDOT system is an electronic system used to place orders for stocks on the NYSE.
•ECNs network major brokerages and traders, so that they can trade between themselves without involving a middleman.
•SOES is an automatic order execution for individual traders with orders less than or equal to 1,000 shares.
•There are three levels on the Nasdaq that vary on the amount of information and access they provide to investors.

Electronic Trading: Level I, II and III Access

There are a variety of ways in which Nasdaq quotes security prices to the public. These levels vary on the amount of information and access they provide to investors.

Level I
This type of quote is most often published on the net as a "real-time quote." Level I consists of real-time bid/ask quotes for securities trading on the Nasdaq stock market. This type of access does not disclose who is bidding or asking for the stock, and it does not show how many shares the market maker is looking for. Real-time quotes show the current quote, but it may be from a different lot than what you are trading. Market makers love clients with this type of access because it doesn't show you the order sizes, and therefore your order may be passed around or held until market makers can profit from your order.

Level II
This type of quotation system is a step up from the Level I. Level II access provides real-time access to the quotations of individual market makers registered in every Nasdaq-listed security as well as the offering or bidding lots that they are looking for. This level of access also gives the name of the market maker looking to trade the stock. It allows traders to see what market makers are showing the most interest in a stock and to identify the patterns for each market maker. Level II access is available over the internet - but at a cost. This can range in the hundreds of dollars per month depending on the company. For clients placing a large number of trades, the firm may waive the access fee because they will make up the costs on your commissions.

Level III
This is a trading service consisting of everything in Level II plus the ability to enter quotes, execute orders and send information. This service is restricted to NASD member firms that function as registered market makers. Level III allows you to enter bid/ask quotes as the trades are being executed right in front of you. It is the fastest way to execute a trade and is typically found only on the trading floors of brokerage firms and market makers.

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.
