      New - CME Reference Data API New Attributes

      Effective Sunday, August 30 (trade date Monday, August 31), to provide more granularity at the instrument level, the following attributes will be implemented on CME Reference Data API  Reference Data API version 2.

      Please Note: All new Reference Data API 2 attributes will be added to Reference Data API version 1 to ensure a seamless transition from version 1 to version 2.  As a reminder, CME Reference Data API version 1 will be decommissioned on December 31.

      The following attributes provide specific information on allowable order quantities at the instrumental level.  These values may be the same as the product level or null.  If the instrument level values are different from the product level, customers should use the information from the instrument record.

      • minIntraGlobexOrdQty
