gzerenner -Interested User- Posts: 4 Joined: Jul 13, 2004 www.poweropt.com	Posted: Jul 15, 2004 12:07 PM Msg. 3 of 6 Hi Jay: The lines showing... ZNE AA Expiration day > 23 -- Date = 1/25/2005 This means that DTN is sending an expiration date of 1/25/2005 and we know that is wrong because an expiration date for an option is never past the 23rd day of the month. For the lines showing... ZNE AA expiration date of 1/25/2005 doesn't match the expiration date of 1/22/2005 for ZNE MA This means that the CALL (ZNEAA) has an expiration date of 1/25/2005 according to the DTN data feed. And that could be wrong since the PUT that matches up with it (ZNEMA) has a different expiration date of 1/22/2005. Thanks for you help on this. Greg Zerenner Poweropt.com

DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Jul 16, 2004 09:19 AM Msg. 5 of 6 ok.. here is what we found: The process we use to add new symbols to the feed/database is automatic for options. The current algorithm we use to add the expiration date is hard coded (because we don't get the expriation date from the exchange with the trade data). This "bad" expiration date, should only be seen on the first day the option was added. Then, nightly, we receive a option data file from OCC which provides the accurate expiration date. The database is updated, and you will have accurate date for those symbols. Thus, you should only see the bad date on the first day, then it is corrected. Obviously, this isn't very good, and our Ticker team is now looking into this to come up with a better algorithm to determine the expiration date as soon as the contract is added. This would explain why the list of symbols you see with bad dates is changing each day. Jay Froscheiser DTN Market Access, LLC.

My application periodically verifies that I've captured all symbols and I just noticed that I have the incorrect dates for many symbols in my database. argh Ted
