there are a few books around you might consider worth reading (if you haven't already), Martin Pring on Market Momentum being one of them, Compleat Daytrader another.
I have been pretty successful with custom, home-made indicators. They are based on stochastics over RSI and ROC. I use different indicators depending on the market. If the trend is strong and clear, I use one group of indicators based on MAs, if we are trading within a range, and there's no clear direction in the market, I use my custom oscillators.
I find however that indicators are only decision support tools. Old fashioned pattern recognition, support/resistance, consolidations/breakouts, tape reading, etc, work for me regardless market conditions.
My best wishes
