I am becoming more of a fan of the theory of scaling in and out of some of my trades. Helps when I am not sure if I am getting in at a bad time and also helps to protect winners when I am right. These days I am not sure how long the run will last. Just part of an overall strategy. Also, you always have to have an exit strategy and know why you are getting into a trade and what your holding plan is and when and how you should get out. Nothing is perfect in the current environment.
