Self Match Prevention

CME Globex Self-Match Prevention (SMP) is optional functionality that allows market participants to prevent the matching of orders for accounts with common ownership, within and across different Globex Firm IDs (GFID) and/or clearing firms.

Use the Request Center Self Match Prevention function to create a SMP ID, for testing in the certification / new release environment.

Note: For additional details, see CME Globex Self- Match Prevention Functionality - Frequently Asked Questions.
In the Production environment SMP ID registration is performed on the Firm Administrator Dashboard (FADB).
