At a launch date to be announced, CME Reference Data API will be enhanced to support Event-Based Contracts. Event contracts are daily-expiring options on a non-tradeable (synthetic) monthly underlying future. Event contracts cash-settle to a fixed value if in-the-money by any amount. Additional details and product availability can be found in the Event-Based Contracts Client Impact Assessment.
These changes will be available for customer testing in New Release on Monday, April 4.
