Best traders should not know many methods, just understand and know how to operate 1 to 2 methods is good enough. Left focus on managing capital and psychology. Slowly the results will be improved.
In short, anything too is not good. Everything should be at a moderate level, we learn a little bit each day, trade a little bit each day, forge a little each day. We go slowly, the results come slowly and go hand in hand throughout our trading journey. If you do not want to lose, firstly traders need to remember 3 things that should not be so in trading!
Knowing a lot of methods is not a bad thing, it actually indicates that traders are person who want to keep learning.
Even when constantly changing the way is also not the wrong thing, could be done to find a method that suitable, fits in the sense of capital, emotions, the time the trader has.
