This can be a very varied question. One can have a just 2-3 basic indicators in his view and still can achieve great heights in trading and on the other hand someone might have like 10 indicators but is still losing all his trades, for me personally I feel keeping a MA band of around 3 MAs covering all the time frames and RSI along with a Momentum indicator liking MACD is enough for you, rest play is with pivot points, quantitative data and patterns.
