To support the rollout of additional options contracts on the CME® Globex® electronic trading platform, the ISIN codes for several instruments will be changing. The ISIN code is the 12 character alphanumeric identifier for each instrument listed on the CME Globex platform and can be found in positions 1 through 12 of all contract-specific CME Market Data RLC-formatted messages (Channel 4 of the Market Data Network (MDN)). CME recommends that customers clear the ISIN codes from existing product tables and reacquire the ISIN codes from the CME MDN MO (m-oh) message on a weekly basis.
