MIAX Options Exchange - Update to the Administrative Information Subscriber (AIS) Feed Specification

The MIAX Options Exchange has just released an updated Interface Specification for the Administrative Information Subscriber (AIS) Feed.

Administrative Information Subscriber (AIS) Feed v2.2a:

  • Route Notification Message (Message Type = “L”, Event Type = “R”) - this message will now include the expected price to which an order will be routed. The expected price is the ABBO at the start of the route timer. There is no direct impact on Members. This additional information will provide further clarity and transparency in the Route Notification message.
Important Dates
  • Firm Test Bed 2 (FTB2) will be available on October 2, 2017.
  • The production rollout is scheduled for early November 2017, subject to SEC approval. The specific date will be announced in a future alert.
The updated AIS specification is currently available for review at MIAX Options Interface Specifications.
