MIAX Options Exchange - Update to the Top of Market (ToM) Feed Interface Specification - Mandatory Change

The MIAX Options Exchange has just released updated Interface Specifications for the Top of Market Feed (ToM).

Top of Market (ToM) Data Feed v2.1 (Required Changes):

  • Simple Double-Sided Top of Market (Best Bid or Offer) Message – Compact Format -- this message will now be disseminated on the real-time feed and provided in retransmissions, as well as continue to be supported for the refresh services.
  • Simple Double-Sided Top of Market (Best Bid or Offer) Message – Wide Format -- this message will now be disseminated on the real-time feed and provided in retransmissions, as well as continue to be supported for the refresh services.
These upcoming changes are to reduce bandwidth utilization and will require ToM consumers to make programmatic changes.  

Important Upcoming Dates:
  • Firm Test Bed 2 (FTB2) will be available on October 2, 2017.
  • The production rollout will begin in the 4th quarter, 2017.  The specific date will be announced in a future Alert.
Updated ToM specifications are currently available for review at MIAX Options Interface Specifications.
