      Price Precision Extension

      In the second half of 2018, CME ClearPort API will support an increase to the maximum price precision from seven to nine decimal places to provide greater price granularity for future launches.

      In Q4 2018, the first application of this new price format functionality, pending regulatory approval, will be implemented for 2-Year Treasury Note futures, future spreads and inter-commodity spreads.

      The attributes listed below will be impacted.
