What you need to know:

  • Effective immediately, Nasdaq® offers additional multicast IP addresses for the proprietary equity data feeds in Carteret, to be known as the "Carteret B" Feeds.
  • Subscribers must complete the Nasdaq Data Feed Request (DFR) to gain access to the new "Carteret B" Feeds.
  • The "Carteret B" Feeds will not be disseminated on a handoff that also contains the original "Carteret A" data feeds. Please see below for additional details.

What is changing?

As part of our continuing efforts to bring ample resiliency and recovery options to the industry, Nasdaq is introducing additional multicast IP addresses for proprietary equity data feeds in Carteret. Data disseminated from these new addresses will be known as the Carteret B Feeds and will be published from a unique source range, independent of the source range of the original Carteret data feeds, now known as Carteret A Feeds. This change allows firms the choice of having an additional redundancy option in Carteret to ensure data continuity.

The Carteret B Feeds are available for the data feeds listed below:

Is there an additional fee to gain access to the Carteret B Feeds?

While there is no additional direct market data charges, certain connectivity fees may apply. Please contact your Nasdaq account representative or reach out to us at Nasdaq Global Data Sales or +1 301 978 5307 (Option 1).

Do interested Nasdaq direct data feed subscribers need to request access to the new 'B' data feeds?

Yes, in order to gain access to the new Carteret B Feeds, direct data feed subscribers will need to complete the Nasdaq Data Feed Request.

When requesting the new data feeds, subscribers must select "Nasdaq Data Center - Carteret B Feed" in the Connectivity Options. In the Comments section, subscribers must include the handoff over which they would like to receive the Carteret B Feeds.

Please note: Nasdaq will not disseminate the new Carteret B Feeds and the Carteret A Feeds on the same handoff. Nasdaq Market Data Procurement will work with subscribers to determine the most efficient handoff over which they would like to receive the Carteret B Feeds.
