Instead of relying on somebody else's opinion, why not just create an account and try it yourself? There are no costs except exchange fees for real time data.
I mean the tech support. What I see on the site is a 24 hour response time to email and two numbers that ring to something called Freedom Voice Mail and a fax machine. i don't want to use data and then if it fails not be able to get a hold of any body, ya dig?
I tried it for just historical data download, it sucks, didn't work and others I have talked to said the same thing. Get what you pay $$$ for.
I've had accuracy problems with their historical data, and so far they have failed to respond to my only support query.
