chainik,
You can subscribe to Marketscreen.com, Thomson, or obviously Bloomberg if you trade enough and have the patience to learn the tool. Some Ritz-Carlton still have Bloomberg terminals.
I do not use Net dollar Accum/Dist as a ST indicator, but it's helpful when deciphering a trend.
Yes I have started to use ISE since they now break out equity from index. New index positions do not seem to be as useful as total index volume (incl closing positions).
I've found equity option volume as % equity OI for near strikes is useful if the percentage is high in the opposite direction of price movement. You can argue the logic on this one based on hedging strategies, but results are results.
I try to take all as a package deal and not using any single indicator as a trigger.
