your fame of mind will reflect in your trading if you wake up feeling like a loser then your trading will reflect that! Some days I can look at a stock and hate it the next day love it even when nothing has charged in the stock.. the way we perceive things like charts, markets, life it's all Mental!! just venting here.. your state of mind really does effect you trading... Just like when I play my elec guitar, one day it sounds great got my amp set up just right the next day I turn it on and have not touched nothing! just turned it on..and it's sounds bad and have to reset the amp all over again if must be my frame of Mind day to day I guess..
not quite. your edge is whatever it is including possibly mental. your execution of the edge is mental even if automated since even black boxes can be overridden.
