Result:
Product Line Scope (E2 and E5): Since the product line is disabled on the triggering session ABC, CME Globex will enforce the mass quote protections at the product group level.
Product Group E2:
Upon a Mass Quote Protection (MQP) trigger, all resting quotes for the E2 product group are automatically cancelled across associated sessions.
Triggering Session (ABC): Quotes in the E2 product group are cancelled with Tag 9775 (UnsolicitedCancelType) = F (Cancellation has been triggered by Mass Quote Protection).
Linked Sessions (BDC and CDE): Quotes in the E2 product group are cancelled with Tag 9775 (UnsolicitedCancelType) = K (Cancellation has been triggered by Mass Quote Protection on Linked Session).
Once the MQP is active, any subsequent Mass Quote messages submitted for the E2 product group from any associated sessions (ABC, BCD, CDE) will be rejected.
To resume quoting, each individual session must reset its MQP by submitting a Mass Quote (tag 35-MsgType=i) message with tag 9773-MMProtectionReset = 1.
Product Group E5:
Unaffected: Product Group E5 is outside the scope of this MQP trigger. All resting quotes and incoming messages for the E5 product group remain active.
