CTA Announcements

The Consolidated Tape Association
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 MKT and other regional exchange (Network B) listed securities. Since the late 1970s, all SEC-registered exchanges and market centers that trade Network A or Network B securities send their trades and quotes to a central consolidator where the Consolidated Tape System (CTS) and Consolidated Quote System (CQS) data streams are produced and distributed worldwide.

The current Participants include the BATS Exchange, Inc., BATS-Y Exchange, Inc., Chicago Board Options Exchange, Incorporated, Chicago Stock Exchange, Inc., EDGA Exchange, Inc., EDGX Exchange, Inc., Financial Industry Regulatory Authority, Inc., International Securities Exchange LLC, NASDAQ OMX BX, Inc., NASDAQ OMX PHLX, Inc., NASDAQ Stock Market LLC, National Stock Exchange, New York Stock Exchange LLC, NYSE Arca, Inc., and NYSE MKT LLC, (collectively, the “Participants”). The Plans govern the collection, processing and dissemination of trade and quote data. The New York Stock Exchange LLC is the Administrator of Network A and NYSE MKT LLC is the Administrator of Network B. The Plans were filed with and approved by the Securities and Exchange Commission in accordance with Section 11A of the Securities Exchange Act of 1934.
