In my experience, most important is to keep it simple. It makes sense to use 1 momentum indicator (I use Stochastic) along with Bollinger bands and some moving averages. Recently, I started experimenting with VWAP too.
- For short-term trading, using EMA crossover like 9 MA and 26 MA makes sense.
- For positional trading, 50 DMA, 100 DMA and 200 DMA is a standard.
