Sharescope EoD I'd agree is not for TA, you might fall for a Nigerian scam letter but using SS EoD for TA would be pushing the realms of possibility. To be fair it is very much a Funnymentals program, and the boss is a very nice man who I'm sure almost patted me gently on the head when I spoke about TA to him once upon a time. (Be kind to loonies sort of thing).
SS RT I've heard good things about - without wishing to start a flame war email chats with some of my users have suggested that SS RT is perhaps better at backfilling data and news? Dunno how true that is, but it has been commented on a few times. I use esignal myself, but those adopting Sharescope RT seem to be as keen on it as the EoD types are on the SS EoD version. I suspect it's another case of just liking one more than the other... list all the competing programs and you'll get 'xxx is the best' votes for all of them, just some progs will get more votes than others.
SS RT is definitely one I'd trial, I think, as well as trying out eSignal and UTA... and doubtless many more! (Tradestation seems rather popular, for example....)
