You always say it's best to learn from the mistakes of others.
From what I've seen others who try to be in every single move usually fail.
Maybe there are some out there who can do it, but the ones I've seen that are successful are very patient and only take the very best setups. When you exit a trade you aren't really exiting based on a setup which justifies going in the opposite direction.
In fact your exit will most likely leave profits on the table, as even some of the very best traders I've read about always note that they wish they could work on letting their profits run.
