The ones I personally like the most are breakouts, dip-buying, momentum, power trends and fading. Breakouts because winning probability is the highest, dip-buying because stop loss is very tight so the risk is the lowest.
Momentum and power trends can really run much bigger and stronger than most expect or think possible, and big gains can be made with trailing stop loss in place and short selling fading on those huge moves after they reach the peak and start down-trending.
