The Consolidated Quotation System (CQS) is the electronic service that provides quotation information for issues admitted to dealings on the American Stock Exchange, New York Stock Exchange, and U.S. regional stock exchanges. The Consolidated Tape System (CTS) provides last sale and trade data for the exchanges. The Consolidated Tape Association (CTA) is the operating authority for CQS and CTS.
