Unique Market Center Identifiers

Data vendors must display a market center identifier for Nasdaq National Market, Nasdaq Small Cap Market, OTC Bulletin Board, and other over-the-counter equity since most of these securities are identified by a four to five character symbol. TradeStation identifies these market centers using the following abbreviations:

• Nasdaq National Market - Nasdaq NM
• Nasdaq Small Cap Market - Nasdaq SC
• OTC Bulletin Board - OTCBB
• Other OTC Equity - OTC
