in the end all good traders have a methodology or quasi system that they stick to and follow.  It's generally personal to them, fits there style and not everyone.  Steve and I for example so some similar things, but we are always quite different traders who have different styles and that's Okay!  Gotta find what fits you.  

In order to find out what fits you, clearly experimentation and time is needed, you need to try and experience different things to find what you really like what fits your style, but eventually you have to just go with something

that thing could be volume breakouts on stocks, or only buying tight coil patterns or wedges with divergences.  Or you may specialize on gold stocks like GDX, or oil stocks.  Or you may find a system for trading ES futures like the reversion to mean method charts I show.  Or even those new Renko charts.  Find something and stick to it
