Facts about CTA data disseminated through SIP / Consolidated Tape

The Consolidated Tape Association (CTA) oversees the dissemination of real-time trade and quote information in New York Stock Exchange LLC (Network A) and Bats, NYSE Arca, NYSE American and other regional exchange (Network B) listed securities. 

The Securities Information Processor (SIP) links the U.S. markets by processing and consolidating all protected bid/ask quotes and trades from every trading venue into a single, easily consumed data feed.

The SIP disseminates and calculates critical regulatory information including the National Best Bid and Offer (NBBO), and Limit Up Limit Down (LULD) price bands among other important regulatory information such as short sale restrictions, and regulatory halts.

Millions of professional and nonprofessional investors have access to real-time prices via the consolidated tapes.

The consolidated tapes simplify compliance and implementation with regulations such as Reg NMS, short sale, limit up/limit down and best execution.
