"You have an excellent product !!!!!!" - Comment from Arely

"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Author	Topic: History data error in "EXE" (6 messages, Page 1 of 1)
David -DTN Evangelist- Posts: 113 Joined: May 7, 2004 I'd rather be...	Posted: May 28, 2004 04:18 PM Msg. 1 of 6 FYI: Symbol EXE has a data error on 5/5/2004 on daily, weekly, and monthly data. The interday chart shows that there was a stock split on that day. (I did not confirm it from other references) Three Issues: 1.0 There appears to be an error in your algorithim for split correction. Not repaired it will occur again. 2.0 History errors that are gross should not hang around for weeks. Data feed errors direct from the exchanges while not desirable are hard to filter as they are small in percentage - however these gross type of errors as in "EXE" should be caught server side. (IMHO) 3.0 I would expect that the interday data would reflect a back split correction too as it causes gross discontinuities. I would like to see some server side data grooming added to the 'wish list'. When spikes / discontinuities occur I get calls. I have been remiss in not doing some basic client side filtering in my application - it is now on my 'to-do-list'.

For exchange sent tick errors, we do plan to put a "questionable tick indicator" in our feed, which will allow clients to choose what to do with this data (we don't want to arbitrarily filter data). In the mean time, if you have bad data, all you need to do is email customer support who will get the info to our MDI (Market Data Integrity) group who can get the data fixed. Split adjustments in intraday data is also in the works. Jay Froscheiser DTN Market Access, LLC. Edited by DTN_Jay_Froscheiser on Jun 1, 2004 at 10:35 AM

Can you double check the symbol so we can look at the data and manually adjust it for splits. Thanks Jay Froscheiser DTN Market Access, LLC.

We have software in test to fix this going forward. It is scheduled for release on 6/19 if all goes well with testing.
