Trading success is the end-result of learning to trade an effective trading method properly (a method or strategy allows for flexibility and fluidity in a trader’s decision making, unlike a rigid ‘system’), gaining a good amount of screen time / experience with that method so that you start developing your own gut feel and trader’s intuition, and then combining that trading feel and skill with strict discipline and patience to stick to your method and to manage your risk properly at all times. Many of these methods, if not most, are complete junk; from day-trading systems, to indicator-based systems, to trading robots that promise to completely automate the trading process, there’s a near endless number of trading methods out there.
