Effective this Sunday, December 7 (trade date Monday, December 8), to optimize trading and instrument management, NYMEX and COMEX products will be migrated to different existing market segments on CME Globex:

• All NYMEX Metals, Softs and Alternative Markets futures and COMEX futures will migrate from market segment ID 76 to market segment ID 78 (tag 1300-MarketSegmentID).
• All COMEX options and NYMEX Metals, Softs and Alternative Markets options will migrate from market segment ID 56 to market segment ID 76 (tag 1300-MarketSegmentID).

With this change, Good Till Cancel (GTC) and Good Till Date (GTD) orders on the migrated market segments will reflect the original market segment prior to the migration.

This migration will use existing market segments and MDP channels on CME Globex.

Client systems will be required to migrate the IP configurations for MSGW iLink and Drop Copy sessions for access to the impacted products.

Additionally, with this migration the MDP 3.0 Market Data Source/Host IPs will also be updated.
