What do you do to a trading strategy that already earns you a good percentage in profit. do you still try improving on it to ensure it does not fail? or do you let it be until it starts showing signs of failure?
There's this saying that if overconfidence makes you stop learning, it can also fail you. That is to say that no matter how confident you are with that strategy you are making profit with, never stop learn about the strategy, learning about it will still continue to improve the simplicity of your trade, you don't have to be too comfortable with something and not prepare for the situation of "what if it fails me? " If trading is very simple, every would quickly learn it and start doing it but because of how unstable and inconsistent it is, that why a trader that is already making profit should not stop learning.
