"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"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
"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
"Excellent datafeed !!!" - Comment from Arely
"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum
"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"You have an excellent product !!!!!!" - Comment from Arely
"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
