"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 cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email
"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim
"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
"Version 188.8.131.52 has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"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
"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
