What you need to know:

Effective Friday, February 16, 2018, The Nasdaq Options Market (NOM) will implement the following changes to the ITTO market data feed:

  • The Seconds, Base Reference Number, and Block Single Side Delete messages will be removed.
  • An Internal Indicator will be added to all messages.
  • The timestamp field will be increased to 6 bytes.
  • All messages using the order/quote reference number 4-byte deltas have been updated to use the 8-byte absolute reference numbers.

Update 04/06/2018: The parallel migration period for ITTO A Feed and FPGA will end at the close of business April 6, 2018.

Update 04/06/2018: The B Feed will be a hot-cut migration on April 9, 2018.

Update 04/06/2018: The Chicago DR will be a hot-cut migration on April 9, 2018 where the 4.0 version of ITTO will begin publishing on the existing Chicago DR IP Addresses. A future communication will be sent regarding IP changes for Chicago DR.

Update 03/23/2018: In advance of the April 9, 2018 hot-cut, Nasdaq will conduct a User Acceptance Test (UAT) on Saturday, April 7, 2018 for firms to test the B Feed and Chicago DR connectivity. The User Acceptance Test (UAT) originally scheduled for Saturday, March 24, 2018 has been rescheduled for Saturday, April 7, 2018.

Why is Nasdaq implementing this update?

Currently on ITTO, Nasdaq publishes a base reference number in long integer form. Base reference numbers begin at 3 billion and have a limit of 7 billion.

In order to mitigate potential concerns on high volume days that the engine will exceed 7 billion and begin duplicating reference numbers that have already been used, Nasdaq is planning to introduce an 8 byte absolute reference number instead of the 4 byte order/quote reference number.
