Trading on emotions is the worst thing for a trader actually. Of course, it's almost impossible to get rid of emotions while we're trading, because you're worried about your accumulations and deposit, however this feeling can be suppressed by the realization of the fact that you have to leave this money. If you understand that you unrlined particular sum of money for trading, then perhaps it will be much easier for you forget about any worryings. Anyway, we're human beings and it's susceptible to us being bothered about everything. I guess due to trainings and strong wills you will be able to leave these emotions.
