Due to the observance of New Year’s Day, CME is closed Sunday January 1st and Monday morning, January 2nd, Chicago time.  The CME will re-open for the evening session on Monday, January 2nd, with a trade date of Tuesday, January 3rd.

The CME pre-open schedule on Monday evening will mimic that of a Sunday start up schedule, with a pre-opening status beginning at 4:00 PM CST, rather than the normal 4:45 PM CST as on a typical Monday.  

Chron should be adjusted so the Order Server and Fill Server start at 4:00 PM CST on Monday and remain up through the Tuesday close at 4 PM CST.

To perform this configuration change, open the \TT\config\ttchron.ini file on your CME gateway(s) and update the “schedule” line as follows:











NOTE: these chron changes should be reverted after the close on Tuesday, January 3rd
