It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email I have used ****** too but the best value is IQFeed." - Comment from Public Forum They are always there for you, and they are quick.
I cannot stop praising them or their technical support. "If you want customer service that answers the phone, your best bet is IQFeed.

I just love your customer service." - Comment from Isreal "After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn "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 decided to stay with you because of the great service through all the volatility." - Comment from Mike DTN.IQ didn’t miss anything and beat my other provider.
"I started a trial a few weeks back before the market went wild. "You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email I Also like the charts a lot." - Comment from Leon The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. "Everything is working great ! Very impressive client. My questions and concerns are always addressed promptly. I would also like to extend a big thanks for the fast and efficient help that I always receive. "I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. Better safe than sorry" - Comment from Public Forum Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. "If you are serious about your trading I would not rely on IB data for serious daytrading. "IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom "Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam The system is very robust and pretty quick considering the extent of data that's available. "Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John "Just a thank you for the very helpful and prompt assistance and services. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe "Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. I may refer a few other people in the office to switch as well." - Comment from Don "I am keeping IQFeed, much better reliabilty than *******. What service!" - Comment from Public Forum Post

I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob My broker's DDE, however, would take as much as 30 seconds to update.
I would see the level II quote change, then your feed update instantaneously. a level II window for some slow-moving options. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum "I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. 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 "I just wanted to tell you what a fine job you have been doing. You are knowledgeable, polite, pleasant and professional." - Comment from Pat I love the product, but more so I am thrilled with Tech Support. (Move your cursor to this window to pause scrolling)
