Event contracts provide access to some of our most recognized global products, including metals, energy, equities, and foreign currencies. Additionally, non-tradable underlying futures are listed to support the options. Event contracts are listed on MDP 3.0 and CME Smart Stream on GCP.

This topic provides an overview of the concepts with which clients must be familiar to process event contracts.

Mass Quote Protections and Price Banding Functionality

Mass Quote Protections for event contracts do not include delta protections (Delta at Group Code, Delta at Aggregate Product Line, Delta at Product Line). The Mass Quote Protection system treats event contracts as having a delta of zero, so any delta protection selected will never be triggered and should not be relied upon to manage risk. Other Mass Quote Protections, including Quote Fills (X), Executions (Y), Traded Quantity (Z), and Sides are available for event contracts. Price Banding is unsupported.

  • The subtype=EVENT value is only eligible for Event Contracts.
