There is no way that a trader will do it, emotions will definitely comes in when trading, its not a demo account, it's  personal money involved so surely emotions will be attached, what a trader just needs to do is to know how to control his or her emotions because failure to control it will definitely be a huge blow, know when to stop when the trade is not going in your way, likewise when the trade is going as planned, greediness is also caused by emotions because when there is no plan or you chose not to stick to the plans, emotional control is kind of greater than TA and FA in my opinion
