Some traders look for reasons to remain in a trade. Other traders look for reasons to exit a trade. While money can be a (valid) reason in either camp, trading with the necessary discipline to adhere to the rules that the trader has chosen for him/her self, is what separates a good trade from a bad trade. That said, one of my rules, regardless of the trigger... do not allow a decent profit to turn into a loss. The caveat is the trader must know what decent means to him/her. IOW, to each their own.
