What is a Market Maker?
A market maker is a Nasdaq member firm that buys and sells securities at prices it displays in Nasdaq for its own account (Principal) trades and for customer accounts (Agency Trades).

Market Maker ID (MMID) Display
The MMID display has five columns (The last four of which may be toggled on and off with the right-click menu) as follows: 

Index/Status - The narrow column at left occasionally has a letter, indicating: l - stale posting; S - short position; and E - partial execution.

Each Market Maker is required to post a bid and ask simultaneously, so comparing the two prices indicates their bullishness. To highlight the bid and ask of a particular MMID, select add tracker from the right-click menu. Remove trackers deletes all the trackers you have added. To find the full name of a Market Maker, select identify market maker from the right-click menu, or click here for a list of important Market Makers.

A "+" or "-" after the Bid or Ask price indicates whether the market maker has increased or decreased the price.

A "+" or "-" after the size figure indicates whether the market maker has increased or decreased the bid or ask share size.

Comparing the times of a market maker's bid and ask prices indicates which one was more recently adjusted.

What do the plus(+) and minus(-) signs next to the price and volume fields signify?
Prices that have moved up from the previous quote have a plus sign (+) after the price. Those with moves down have a minus sign (-) after the price.

What are the Regional Exchanges?
The Regional Exchanges are filled in the MMID fields when any other stock other than Nasdaq listed stocks are requested. These regional exchanges include the Pacific Stock Exchange (PACX), the New York Stock Exchange (NYSE), the Boston Stock Exchange (BOST), the Cincinnati Stock Exchange (CINC), and the Chicago Stock Exchange (CHGO).
