National Market System Plans
The Securities and Exchange Commission (SEC) requires that each participant in an effective National Market System Plan (NMS Plan) ensure that a current and complete version of the NMS Plan is posted on a central web site. Below are links to the central web sites that provide copies of each of the three NMS Plans in which FINRA participates. In addition, each of the web sites provides any proposed amendments to these plans that are pending with the SEC.
National Market System Plan Governing the Consolidated Audit Trail
This plan governs the development, implementation and maintenance of a consolidated audit trail that collects and accurately identifies every order, cancellation, modification and trade execution for all eligible securities.
Regulation NMS Plan To Address Extraordinary Market Volatility
This plan governs the establishment, operation and administration of a market-wide limit up-limit down mechanism that is intended to address extraordinary market volatility in NMS stocks, as defined in Rule 600(b)(47) of Regulation NMS under the Exchange Act. The Plan sets forth market-wide limit up-limit down requirements designed to prevent trades in individual NMS Stocks from occurring outside of the specified price bands and also governs quotations in NMS stocks. These limit up-limit down requirements would be coupled with Trading Pauses, as defined in Section I(X) of the Plan, to accommodate more fundamental price moves.
National Market System Plan for the Selection and Reservation of Securities Symbols (The Intermarket Symbol Reservation Authority, or “ISRA” Plan)
The ISRA Plan governs the establishment, operation and administration of a uniform system for the selection and reservation of securities symbols (the “Symbol Reservation System”). Self-regulatory organizations (SROs) that have joined the plan utilize this system to reserve one- to five-character root symbols, utilizing a web-based tool developed and maintained by the Options Clearing Corporation, the Plan Processor.
Consolidated Tape Association Plan/Consolidated Quotation Plan (CTA/CQ Plans)
The CTA/CQ Plans governs the collection, processing, and distribution of quotation and transaction information for exchange-listed securities (excluding those securities listd on the Nasdaq Stock Exchange). The data reflected on the consolidated tape (Networks A and B) is derived from various market centers, including securities exchanges, FINRA, electronic communications networks (ECNs), and other broker-dealers. Under the CTA/CQ Plans, all U.S. exchanges and associations that quote and trade exchange-listed securities must provide their data to a centralized securities information processor (SIP) for data consolidation and dissemination.
Joint Self-Regulatory Organization Plan Governing the Collection, Consolidation, and Dissemination of Quotation and Transaction Information for Nasdaq-Listed Securities Traded on Exchanges on an Unlisted Trading Privilege Basis (OTC UTP Plan)
The OTC UTP Plan governs the collection, processing and distribution of quotation and transaction information for issues listed on the NASDAQ Stock Exchange. UTP data is derived from various market centers, including securities exchanges, FINRA, ECNs, and other broker-dealers. Under the OTC UTP Plan, all U.S. exchanges and associations that quote and trade NASDAQ-listed securities must provide their data to a centralized SIP for data consolidation and dissemination.
The CT Plan is a new national market system plan governing the public dissemination of real-time consolidated equity market data for national market system (“NMS”) stocks. The Plan governs the collection, processing, and dissemination of quotation and transaction information for exchange-listed securities. The data reflected on the consolidated tapes (Networks A – for New York Stock Exchange LLC, B – for NYSE American LLC, NYSE Arca, Inc., Cboe BZX Exchange, Inc., and other regional exchanges, & C for NASDAQ-listed securities ) are sourced from various market centers, including securities exchanges, FINRA, and other broker-dealers. Under the CT Plan, all U.S. exchanges, associations, and market centers that quote and trade exchange-listed securities must provide their data to centralized securities information processors (SIPs) for data consolidation and dissemination. The Plan will become operative within 12 months of the August 6, 2021 Effective Date.
National Market System Plan Establishing Procedures Under Rule 605 of Regulation NMS
This plan establishes procedures under Rule 605 of Regulation NMS. Rule 605 of Regulation NMS was originally adopted in November 2000 as Rule 11Ac1-5 under the Securities Exchange of 1934. In 2005, Rule 11Ac1-5 was re-designated as Rule 605 with the adoption of Regulation NMS. Rule 605 generally requires a market center that trades NMS stocks to make available to the public monthly electronic execution reports that include uniform statistical measures of execution quality.
