"Version 4.0.0.2 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 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
"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles
"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum
