As announced last November, CME Group is enhancing its CME Globex systems to support up to 9 decimals, and Clearing systems up to 8 decimals of price precision. The technical changes are across all CME Group products, and your systems need to be ready irrespective of the asset classes and contracts in which you are active.

These changes have been widely communicated by our Global Account Management and Clearing House Operations teams who have been in touch with customer technology and operations teams since last October, but we are taking this extra step to confirm all key customers are informed. Please check with your internal teams and vendors to confirm all your systems will be ready.

• This change will impact Order Routing (iLink), Market Data (MDP), Drop Copy, Straight-Through Processing (STP) and Clearing services according to the time frame below.
• The first of these technology changes will be on August 12, 2018, for which the market data schema change to MDP will require client systems using MDP to be ready in order to correctly display CME Group Market Data.
