Effective Sunday, November 18 (trade date Monday, November 19), to simplify the submission of trade entry reports, CME ClearPort will support trade entry for Calendar Spread Options (CSOs) on products, typically Agricultural, that do not list consecutive monthly contracts.

This enhancement will be available in New Release for customer testing on Wednesday, November 7.

Price Precision Extension

CME Group is implementing end-to-end technology changes to support increased price granularity. Currently, CME Group systems support a maximum of 7 decimals. With this initiative, products with up to 9 decimals may be listed and traded. Effective Sunday, January 13 (trade date Monday, January 14), pending regulatory approval, the 2 Year Treasury Note futures and spreads will move from 7 decimals to 8 to support trading at 1/8 of 1/32.

Customers are encouraged to move to support 9 decimals now; but there are no plans to list a product that uses the 9th decimal at this time.

For more on impacted products and CME Globex, iLink messaging, Drop Copy and Market Data impacts, view the CME Globex Client Impact Assessment.

These enhancements are currently available for testing in New Release.
