are you saying never second guess, just get out or sell?
I am a pure technical trader when I trade. I rely exclusively on the signals. Early on during my learning curve I found myself kicking myself for not heeding the sell signals as they happened and watched as several no brainer profit taking opportunities turned into a loss.
It took several months to fully trust the signals and although they are never 100% correct, they will be right many more times then they are wrong so I like the odds of just trading the signals.
