"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
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"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 like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe
"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark
"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. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam
"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
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
