Rather prefer ATAS. Price action and supportive volumes. But this is not the only factor to rely on. Everything goes in complex.
What I do not use for sure (or rarely) are indicators.
As for volumes, probably this book will be interesting for you:
Murphy, John J.:
Technical Analysis of the Futures Markets
Oh, thanks for advise. Now I learn Steve Nison 'Japanese Candlestick'. Next will be Murthy.
Trading without indicators has own features. Is it mean that you don't use such a definition as 'divergence'? What about a wide-known 'gap with CME'?
