"Excellent datafeed !!!" - 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
"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
"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
"Its working FABULOUSLY for me!! Holy cow...there has been so much I've been missing lately, and with this feed and Linnsoft software...I'm in the game now." - Comment from Chris R.
"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
"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"I am very pleased with the DTNIQ system for quotes and news." - Comment from Larry
"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
