"Version 4.0.0.2 has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.

"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

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Tried to restart iqfeed several times so that it might connect to different servers, no luck. No app. issues as this was the ask I was getting using the c++ level1 example too. Cheers, lvarga

Was there a certain time you were seeing the discrepancy? From Markt Data. Looking through minute data on IQ, there are no problems that I see for today. When I look at a 1 minute time and sales, I don’t see any minutes where the quotes are the same from 1 minute to the next. If the customer needs us to look at this further, she would need to be more specific with the exact time that this happened but it appears that there isn’t a problem. I would assume she was on a bad server or something along those lines. Even if there was a problem, it appears to be fixed now so not a lot we can do other than adjusting the old minute data.
