NK, yes we are always looking at other data providers besides yahoo and IQfeed, there is the possibility for IB in the near future and a few others, will keep you all informed.
Sam, there isn't any recent data on AIX (unusual for yahoo i know) available, so no analysis to do.
Charlie, yes just plain normal short positions, no derivatives, and yes you don't have to watch the software all day, we have audio alerts, email and twitter alerts, you can receive your signals straight to your mobile phone, so you can trade anywhere, anytime.
