Sample OneChicago datafiles now available via Internet

Sample CME datafiles with OneChicago products are now available via the CME's FTP site on the Internet, at ftp.cme.com/pub/span/data/cme/one.

These can be accessed without charge via either a Web browser program such as Netscape Navigator or Internet Explorer, or an "FTP client" program such as WS_FTP.

The types of sample files available will include: (a) price files, (b) SPAN� files, (c) TREX trade confirmation messages, (d) Trade Register datafiles ("machine-readable trade register"), and (e) Trade Register report files. As previously announced, please note that OneChicago products will appear in CME-provided datafiles as ordinary CME products, with two exceptions: (a) on TREX trade confirmation records, the "trade source ID" field will identify the trade as being in a OneChicago product, and (b) on the Trade Register datafile, the "market indicator" field will likewise indicate that the trade and/or position record is for a OneChicago product.

Files currently available are:

• Sample price files and SPAN files (in both the packed and unpacked formats) for July 15th and July 18th, and
  
• A spreadsheet listing all of the single-stock futures and narrow-based-index futures to be launched, together with (a) the ticker code for the underlying security, (b) the ticker code for the OneChicago future, and (c) the two-byte CME clearing system code for the future.

More sample files will be made available day by day as testing progresses.
