So to start, we have to believe that trading is a real science, and emotions do not not exist in science. In all history, there was no scientist who made a theory or proved a reality through  his emotions. So we have to be ok about the idea that trading is based only on studies, strategies and reality. Sometimes we find ourselves infront of a complicated situation that even logic does not offer us the solution so we find ourselves obliged to believe in our selfs and in our choices wich are based on emotions.
