As a reminder, CME Group internal testing in the Production environment can occur during the weekend. Any trades or market data generated during these tests should be disregarded.
Clients can connect to CME Globex services beginning at 10:30 a.m. Central Time (CT) Sundays to prepare for weekly start-up. Clients should ensure all services are disconnected by 5:00 p.m. CT Fridays to avoid receiving internal test data.
CME Group Holiday and Trading Hours are also available on the CME Group website.
