Data Technical News #2014 - 12
REMINDER: New Multicast IP Address for Select NASDAQ OMX Proprietary Data Feeds

What is changing?

As outlined in Equity Technical Update #2013-24, NASDAQ OMX^® is undergoing a technology refresh on The NASDAQ Stock Market^® (NASDAQ^®). State-of-the-art network and server equipment will be deployed in order to achieve a more efficient and more robust infrastructure to support the growing needs of our customers. The refresh is part of the NASDAQ OMX commitment to leading the industry in technology standards.

As part of the transition, NASDAQ OMX will introduce new IP addresses for the New York Metro Area data center on Monday, January 27, 2014, for the following data feeds:

• NASDAQ MatchView
• NASDAQ Net Order Imbalance Snapshot (NOIS)
• NASDAQ Pathfinders
• NASDAQ Velocity and Forces



These data feeds will continue to be available on the current IP addresses through close of business on Friday, April 25, 2014. Firms must make the transition to the new IP addresses to prevent loss of data as of Monday, April 28, 2014.




Please note: The IP addresses for the Mid-Atlantic Region will remain the same for the mentioned data feeds.

To request access to the new IP Addresses, please contact Market Data Procurement.

What are the affected data feeds?




NASDAQ MatchView is a real-time direct data feed that provides a view into what the NASDAQ OMX execution system sees as the prevailing Best Bid and Offer (BBO) of the other exchanges.

NASDAQ Market Pathfinders (Pathfinders) provides aggregated real-time, intraday data based on trades from the integrated NASDAQ system. It measures the market sentiment based on the aggregated, real-time trading decisions of NASDAQ market participants. Market Pathfinders attempts to replicate the visible activity and audible noise that experienced floor traders use on a physical trading floor to detect changes in buying and selling interest, market direction, momentum and liquidity.

NASDAQ Velocity & Forces (NASDAQ MAX) is designed to provide a new level of transparency for trading activity in NASDAQ. NASDAQ MAX offers customers new ways to analyze the markets through NASDAQ Velocity and Forces — pre-trade indications of price movement, momentum and liquidity.

NASDAQ Net Order Imbalance Snapshot (NOIS) provides alerts based on net order imbalance data for newswire services.
