Registering and Managing Globex Operator IDs (Tag 50)
Operator IDs, previously known as Tag 50 IDs, identify authorized trading participants (individual or ATS operator group) that transmit messages to / from CME Globex and operate trading systems.
Registration of Globex Operator IDs are required for individual members, employees of a member, employees or contractors of a clearing or corporate member. CME Group reserves the right to require the registration of all market participants.
Globex Operator IDs must be unique at the Clearing Member (Registered Entity) and Trading firm level. Clearing member firms must ensure Globex Operator IDs are registered and correct information is maintained in the Exchange Fee System (EFS).
