"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"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

>Originally posted to Developer List with no response. Please respond. There is a major problem with IQFeed tick data from EUREX. Thank You.

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:
