CME STP FIXML - Regions and Resiliency

CME STP FIXML operates in two GC regions, Eastern and Central United States. Client systems will connect to the same service URL, regardless of which region is active.

Clients should note that the x-cme-token, which is used by client systems for ongoing subscriptions and for multi-batch queries, will not be valid across regions. Upon regional failover, users will receive a TradeCaptureReportRequestAck with the attribute @txt="x-cme-token is no longer valid. Please initiate a new subscription".

Please see more details in CME STP FIXML Session Layer topic.
