I try to keep it simple. Too many indicators can just confuse things.

I use one indicator for volatility (Bollinger Bands), one for volume (volume profile), and one for momentum (Chande, RSI, or something similar). Candlestick reading and horizontal S/R is also important. Major MAs like the 20-day can also be good to have on the chart, as price tends to gravitate towards them (mean reversion).
