This is a huge topic, but here I stick to ‘what do I need to be able to do?‘ without delving into the neuroscience and
To be able to change my view according to PA and not get married to my expectations.
To be able to wait for a level or a valid set up before entering a trade.
When I lose, I just have to carry on trading the same setups. If I get disheartened and inconsistent after losses, I will never win.
Even when I am either (a) excited about profits and feel like I can conquer the world or (b) in despair after a string of losses, I must still pay detailed attention to the market, to levels, to trend lines and to risk control. Mistakes on any of these fronts are costly – whether from missed trades, too little risk on a great set up or too much risk on a bad one. If I am not focused, I should not trade.
