Over the course of the last year, CME Group has worked to transition its price feed from FIX/FAST to MDP 3.0. This new protocol replaces FAST compression and implements Simple Binary Encoding (SBE), which is optimized for low-bandwidth, very-low-latency, direct-data access.
MDP 3.0 became CME’s “feed of record” on October 1, and the FIX/FAST price feed will be decommissioned at the end of this month.
In preparation for this transition, our TTNET™ hosting operation has been exclusively running on MDP 3.0 (TT CME Gateway 7.18) since September 18. While we encountered some stability issues with the initial rollout, we worked diligently to address all issues as they arose. We released two incremental gateway packages over the last month to provide customers with fixes as quickly as possible. We will continue to proactively monitor our systems and aggressively address any issues that may arise as a result of the transition to MDP 3.0.
To that end, later this week, we will release CME Gateway 7.18.15, which will further enhance stability on the new price feed. We encourage all customers to upgrade as soon as possible in advance of the October 30 deadline. If you require assistance with the migration, please contact your local Technical Account Manager.
