CME Group to launch new iLink 3 Cancel On Behalf functionality
Starting Sunday, February 12, 2023 (trade date Monday, February 13), CME Group will launch a new Cancel On Behalf functionality that allows iLink 3 sessions to cancel orders and quotes from different iLink 3 sessions under the same CME Globex Firm ID (GFID).
This functionality will be enabled for all CME Group futures and options on futures on CME Globex. It is only available on iLink 3 sessions using the schema version 8. Cancel On Behalf is not allowed on iLink2 orders and quotes.
In addition to the new Cancel On Behalf functionality, CME Group will allow client systems to block future mass quotes submissions from a different iLink 3 session under the same GFID via Quote Cancel (tag 35-MsgType=Z) message using a new tag 9182-QuoteEntryOpen = 0. The original session will have the ability to remove this block by submitting a Mass Quote (tag 35-MsgType=i) message with tag 9182-QuoteEntryOpen = 1.
This change is currently available in New Release for customer testing.
Certification in AutoCert+ is required to utilize the new Cancel On Behalf functionality. The new AutoCert+ test suite is currently available for customer certification.
