Scheduled CME UAT maintenance window - every Wednesday 5am-12noon CST Please refrain from testing during this time as the environment may be unavailable, or exhibit erroneous behavior, such as:

  • Duplicate entries in a Price Depth book.
  • Receive SnaphotFullRefresh messages without a TradeDate and MDSecurityTradingStatus.
  • Incorrect SecurityStatus messages.

These issues are isolated to the New Release environment and will not occur in Production.

The SecurityGroup field is used for symbols where globex symbols are of format <Asset><M><YY> => Product code + 1 digit month + 2 digit year.  If the SecurityGroup is populated on SecurityStatus messages, it will be expected to be populated back on all the client requests.


If Implied Liquidity is available for the subscribed instrument, then it will be delivered as as separate MDEntries to regular Bids and Offers. 

The book update message for a Market by Price (MBP) multiple-depth book reports modifications to prices, quantities, and order count; the data block for an implied prices book reports modifications to prices and quantities only.

The MBP multiple-depth book should be used in conjunction with the implied prices book to create an accurate book for all contracts with implied functionality. To create a consolidated book, the multiple-depth book and the implied book must be built and managed separately, then consolidated to reflect the current state of the market.

Implied Liquidity may or may notbe available during the day, depending on market activities. If no Implied updades are delivered, it implies that no Implied Book is currently available for the security. 


TradeDate may or may not be published on the initial SecurityStatus messages, however it will be updated as it becomes available.
