You just got to find something that works for you more often than not and stick with it, Plan A. However, always use Plan B (alternate exit strategies) and Plan C (stop loss points.)
Following the plan is rarely easy due to the emotions all us humans (and in your case doggies) have, but the ability to follow the plan (combined with good money management techniques) is more often than not what separates the winners from the losers in this business.
