"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
"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'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.
"Can I get another account from you? I am tired of ******* going down so often" - Comment from George
"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah
"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"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
