I started trading with fundamental analysis, moved to technical and quantitive analysis, and later explored cracking sentiment and following smart money. My takeaway was that none of these work isolation, and you need to discover what works for you.
My advice was to experiment with all these trading strategies and learn what works best for you.
In a separate reply, I echoed the progression through fundamental, technical and quantitive analysis, sentiment, and smart money, then advised experimentation; I did not report which approaches worked best for me.
