"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 just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"As a past ******* customer(and not a happy one), IQ Feed by DTN is a much better and cheaper product with great customer support. I have had no problems at all since switching over." - Comment from Public Forum
"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
"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 would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"The people at Nirvana have very nice things to say about your company and I can see why! Price and service is a potent combination." - Comment from Ed
"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
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah
