"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.
"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 keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don
"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe
"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
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email
"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart
"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
