"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
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"Can I get another account from you? I am tired of ******* going down so often" - Comment from George
"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum
"I just wanted to let u know that your data feed/service is by far the best!!! Your unfiltered tick data is excellent for reading order flow and none of your competitors delivers this quality of data!" - Comment from Peter via Email
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate
"I am very pleased with the DTNIQ system for quotes and news." - Comment from Larry
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
"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
