I think every aspect that could help in making good trades must be considered. Whether its the psychology or the emotions that a person feels whether he's winning or losing is always critical. It's because how a person reacts after a loss or a win would make or break how his investment would go. For those who are trigger happy and do not think of the consequences of their actions, especially after a loss, would surely result to them not having the chance to get their losses back. It's better to think things through instead of acting out without even a thought.
