"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'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"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

"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post
