FIX/FAST Operators Release
The life cycle of the FIX/FAST protocol, including streamlined FIX/FAST, is rapidly approaching its end as an industry standard in the United States. †The OPRA connected exchanges are eliminating FIX/FAST entirely by the end of this year. Given the increased availability of bandwidth as well as high speed connections such as co-location, compression has become less critical. In the short term, we are removing certain field operators (copy, default, delta and increment) from our data feed. In the longer term, CME Group continues to evaluate a next generation market data protocol.
These operators will be removed from all production FIX/FAST and streamlined FIX/FAST channels on the Market Data Platform by Sunday, November 4, 2012. A detailed schedule of the remaining channels is now available online.
New templates will be required for the impacted channels. Per the normal process, the new templates are currently available on the CME Group ftp site for New Release and Production, along with the current and last generation templates. More information on template management is available in the Client Systems Wiki.
Please Note: CME Group recommends customer systems pull the templates from the CME Group ftp site every week, prior to Sunday startup.
These changes are currently available on all FIX/FAST channels in the New Release environment.
As a result of this launch, bandwidth utilization over the Market Data Platform will ultimately increase. CME Group is contacting customers who may have over-subscription risk.
†Please note: CME Group is not a member of the Options Pricing Reporting Authority (OPRA).
Global Account Management will be hosting a live webinar and interactive discussion on the FIX/FAST Operators Release on Thursday, July 12.
Reduction in User Defined Spread (UDS) Instrument Maximum Number of Legs
Effective Sunday, July 15, 2012, the maximum number of outright legs allowed on a User-Defined Spread (UDS) will be reduced to 26. Currently, the maximum number of outright legs is 40.
Security Definition Requests (tag 35-MsgType=c) with more than 26 outright legs will be rejected with Business Level Reject (tag 35-MsgType=j).
Recursive UDS functionality will continue to be supported, and can be utilized to build strategies with more than 26 outright legs.
This change is currently available in New Release for customer testing.
Details on UDS functionality are available online.
CME Globex Performance Release
CME Group is implementing iLink and FIX/FAST infrastructure upgrades to the CME Globex electronic trading platform that will result in reduced message response times and faster market data messaging. This release is expected to significantly reduce iLink round trip times and improve FIX/FAST performance. As a result, bandwidth utilization is expected to increase by 10-20%.
New information is now available in the Client Impact Assessment on the move to single IP for iLink sessions in the production and disaster recovery environments. Information on the iLink launch date for the Disaster Recovery environment on November 4, 2012, is also available.
This release also features iLink messaging changes. Detailed information on this launch, including impacts and launch schedules, is available in the Client Impact Assessment.
The FIX/FAST launch will be phased in over 5 weekends, August 26 through October 7, during which the source IPs for each channel will change. The iLink launch will feature an Early Adopter period, October 7 through October 12, and a production launch Sunday, October 14. All iLink sessions must migrate to new IPs and ports in order to access the new high performance production environment.
Customers who wish to participate during the Early Adopter phase must select the sessions that will be migrated and inform their Global Account Manager no later than Wednesday, October 3. Please note: To minimize the risk of business interruptions, CME Group strongly recommends that customers participating during the early adopter phase direct no more than 20% of their sessions to the new IPs and ports.
Customer certification is not required, but CME Group strongly recommends all system providers test these changes thoroughly in New Release. Good 'Till Cancelled and Good 'Till Date (GTC/GTD) orders will not be impacted.
