Emotions in trading could cause you a big stress but on the other hand it's hard to be fully cold, we are not machines. The key is find some kind of balance between cold mind and the heart because sometimes you just have the feeling if something is wrong or right, we have all experienced that.
One emotion that you never, ever should give a chance is panic, this can really cost you a lot and it will totaly blind your common sense.
Right.We cannot totally disregard our emotions in trading knowing that we are just humans.We need self-control all the time.If we want to make a good trading,i think we should focus more on profits and not on emotional satisfaction.Yes panic selling will really make the situation worst in the end.
