I disagree, a lot of trading has to do with intuition esp daytrading. If you trade without it your better off buying lottery tickets.
95% of my intuition loses money, I have just automation running while I design other systems. I have over 20 years of journals that prove to me I am not a seat of the pants trader. I am totally rule based trader which in itself forces me to have discipline, at some point you throw up your hands and say "screw it" and take all the signals, too tiring to think and proven thinking can't remember as well where probabilities give better responses based on past. I simple don't know of anyone who been trading over ten years that don't have rule based systems.
Of course intuition could be someone who has good memory and did much back testing to base decisions.
