Effective trade date Tuesday, October 1, CME Group will revise the CME Globex Messaging Efficiency Program to more effectively target messaging that can negatively impact system performance, impair efficient access to the market, and create unnecessary infrastructure and processing costs for market participants.
The existing Program will remain in effect through Monday, September 30, and will be retired when the revised Program is implemented on Tuesday, October 1.
The following changes will be made under the revised Program:
- Message scoring will be calculated and applied for the entire CME Globex trading session versus the current hours between 7:00 a.m. – 3:15 p.m. Central Time (CT)
- Previously excluded instruments and back months will be included and scored at a reduced weighting
