When it comes to trading on a professional level, it is important to establish a set of rules that will help make your success achievable.  The rules are to be adhered to and carefully constructed to ones trading strategy.  One of my most important rules is no more than 4 trades per day.  This rule was established over time when I realized that over trading results in giving back gains, then ultimately it results in a negative day.  Some traders are able to make up what they have loss but its a psychological battle with me which will result in a greater loss.  So instead of going through the mental implications I just established a rule that will curve the unnecessary torture.  Through back-testing my strategy, I also found that my first trade of the day was usually the best trade.  The first trade yields the higher gains. If my first trade is more than I want in terms of my day quota, I would just make that trade my last and only trade for the day. I have many rules that guides me and forces me to trade more like a robot.  And we know that robot rarely make an error unless its a program error.  Everyday trading gets easier when I follow my rules and plan. Less stress and more Gains.
