"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"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
"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat
"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
"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 am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
