    • Beginning trade date October 21, 2013, CME Group will begin accepting morning position adjustments via a morning PCS file. This will allow for an automated solution, where currently positions may be adjusted only via the CME Group Positions User Interface.
      Messages within the new adjustment file should be in same format as the nightly PCS file, and may be submitted even if there has been no change in position. The only difference between the nightly file and the morning file, other than quantities, will be the name of the file itself. The naming convention for the morning PCS file is:
      PCSADJ.CMF_xxx.xml, where “xxx” is the firm number submitted in the nightly file.
      CME Group will accept files with a BizDt representing either the current (morning) or prior (most recent night cycle) Clearing Business Date. This means that, other than the file name, the standard PCS process may be used to create the morning adjustment file. Current day’s trades may not be included in the PCS positions reported in the new adjustment file. A step should be added to the standard process to remove the new day’s trades (but not as-of trades) if they exist. 
      The file will not be accepted after 8am each morning. Files submitted after Friday night’s processing will be processed between Sunday afternoon startup and the regular 8am (Chicago) cutoff time Monday mornings. That is, you will not see morning position adjustments on Saturdays.
      For questions or further information please contact CME Clearing Services (CCS) at 312-207-2525 or ccs@cmegroup.com.
