James, one of my favourites is Acc/Dis because im pretty big on volume. I dont actully rely a lot on indicators. I think you can tell a lot from looking at price movements, price patterns and volume. Indicators for me, really just tell me what I already know.
Still, I do use them as sometimes they can show underlying weakness thats not clear to the naked eye on a chart.
I like RSI, it can really help pinpoint support areas, moreso than stochastics IMO as it tends to follow the trend better.
