What you need to know:

Effective Monday, November 6, 2017, Nasdaq will be delaying the publication of Nasdaq-listed End of Day Trade Summary Messages on NLS Plus by 15 minutes. The new scheduled delivery time of all summary messaging will be standardized at 8:15 PM EST.

What is NLS Plus?

NLS Plus is a comprehensive, but affordable data feed providing access to all Nasdaq U.S. markets' last sale data as well as consolidated volume. NLS Plus includes all trade data from the following Nasdaq markets for U.S. exchange-listed securities:

  • Nasdaq
  • FINRA/Nasdaq Trade Reporting FacilityTM (TRFTM)
  • Nasdaq BXSM (BXSM)
  • Nasdaq PSXSM (PSXSM)

What are the benefits of NLS Plus?

NLS Plus is designed to provide a comprehensive view into the trading activity on U.S. equity exchanges. In addition to the benefits of Nasdaq Last Sale, NLS Plus supports:

  • Full Nasdaq market coverage: NLS Plus reflects all transactions from the Nasdaq U.S. equity market systems: Nasdaq, FINRA/Nasdaq TRF, Nasdaq BX and Nasdaq PSX.
  • Comprehensive security coverage: NLS Plus covers all U.S. equity securities including:
  • Tape A 2013 New York Stock Exchange (NYSE)-listed securities
  • Tape B 2013 NYSE MKT- and NYSE Arca-listed securities
  • Tape C 2013 Nasdaq-listed securities
  • Consolidated market volume: NLS provides cumulative consolidated volume on each trade report message. NLS Plus cumulative volume reflects real-time trading activity across all U.S. exchanges for Tape A, Tape B, and Tape C securities.

NLS Plus enables firms to create dynamic stock tickers, portfolio trackers and time/price graphs products for public use.

What is an End of Day Trade Summary message?

NLS Plus publishes an End of Day Trade Summary message on a daily basis. This message contains the High, Low, and Last Price, as well as consolidated volume on all active Nasdaq-listed and non-Nasdaq-listed securities. Currently, the EOD Trade Summary messages for Nasdaq-listed securities are sent at 8:00 PM EST, and EOD Trade Summary messages for non-Nasdaq-listed securities are sent at 8:15 PM EST.

How will this change affect NLS Plus?

Nasdaq will be modifying the transmission schedule for EOD Trade Summary messages to align distribution of both Nasdaq-listed and non-Nasdaq-listed securities to the standard time of 8:15 PM EST.

Why is Nasdaq making this change?

This change is being made to avoid the potential for missing late reported trades and to further standardize consumer expectations by aligning distribution of all EOD summary messages at one consistent time of 8:15 PM EST.

Will anything change in the message itself?

No. There will be no changes to the actual EOD message itself, only the time in which it is distributed.
