"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email
"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
"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
"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark
"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email
"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
"I am very happy I changed. I love the product, but more so I am thrilled with Tech Support. You are knowledgeable, polite, pleasant and professional." - Comment from Pat
"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah
"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
"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin
