"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"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

"IQ feed is brilliant. The support is mind-bending. What service!" - Comment from Public Forum Post

"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

Author	Topic: EUREX Tick Data Problem: actual trade volume or summation? (4 messages, Page 1 of 1)
sd_cm -Interested User- Posts: 22 Joined: Aug 23, 2004	Posted: Dec 1, 2004 05:02 PM Msg. 1 of 4 If volume of EUREX tick data trades are added up they exceed the reported exchange volume by a factor of nearly 10. For example, on 12/01 EXZ4 has ticks totaling 4,116,149 with the exchange reporting 501,961 contracts traded. After looking at the tick data I think this may be due to summing the volumes instead of reporting actual trade volume. When a new trade price occurs the volume is "reset", but multiple trades at the same price have their volumes' added together. Is this a DTN error or a EUREX error and how can we fix it? The enclosed tick stream from EXZ4 demonstrates the problem: DEBUG: onPU: Wed Nov 24 13:00:00 CST 2004 2898.0 150 DEBUG: onPU: Wed Nov 24 13:00:00 CST 2004 2898.0 154 ( actual trade volume=4) DEBUG: onPU: Wed Nov 24 13:00:00 CST 2004 2898.0 162 ( actual trade volume=8) DEBUG: onPU: Wed Nov 24 13:00:00 CST 2004 2898.0 172 ...

I have been looking into this problem since your post and found it is a problem with our quote provider. EUREX does not transmit a complete quote with it's trade update. They send each piece (volume, bid/ask) separately. Apparently, this confuses their system resulting in the misinterpretation of the data. Please bear with us. We are in the process of replacing our feed source. Glenn Benes Glenn Benes DTN Market Access, LLC.
