"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"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

"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
