Dear CME^® Globex^® Customers,

To assist development to the new CME options functionality, CME is now replaying order flow data in the CME certification environment for certain contracts. This data mimics trading in the CME production environment, but at a slower pace. This replay runs from 8 a.m. - 5 p.m. Central time (CT), Monday through Friday.

Please view the contracts currently replayed here. The contract selections will be updated as contracts expire.

Please note: CME encourages all firms to test daily 10 a.m. - 12 p.m. CT, so that the CME certification environment trades more like production during these hours.

If you have any questions, please contact your CME Globex Account Manager at 312.634.8700; or in Europe at +44.207.623.2550.

Thank you,

CME
