"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"Version 126.96.36.199 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."IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John
