"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah
"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
"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.

"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"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

I'm looking at tick data on the @ES# instrument and I'm seeing all sorts of bad data. It may not be just that symbol, it's the only one I have looked at.

Some ticks have dates with bad years like 22010-MM-DD, 202010-MM-DD, 2012010-MM-DD, and 20102010-MM-DD.

I'm also seeing some ticks with an incorrect number of fields like:
2010-08-04 10:08:12,1122.50,1,519776,513811,1123.75,1124.00,11823938,0,0

That tick has an extra field that shouldn't be there (looks like the volume got duplicated or something).

Can you give me some more information? Did this just start happening today or has it happened in the past?

What is the request you are using? If you re-request the data do you get the same data again?

Are you making multiple requests to the feed at the same time?

I suppose it could be a bug in the platform. It seems like mostly older dates (a week or two ago) when pulled from historical data.

I'll have to wait till the end of the day so I can pull ticks that old, then I'll try refreshing from a fresh install of the platform and see how that goes. I'm just requesting one symbol at a time. I'm not sure what request the platform uses but I can find out.

I have never seen this before so that's why I was thinking it might be the data itself but now I don't know.

We took a look at the data on the servers and didn't see any corruption.

Let me know what you find out on your end.

I think it's just a bug in the platform that was introduced with recent updates. I was able to recreate the problem just with last weeks data and it seemed somewhat random.

Sorry for the noise but I think everything is working fine (or will be once they fix it ).
