"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"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
"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
"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
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark
"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn
"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
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
