Winning traders view each trade setup as just another execution of their trading edge, they then think about how to minimize their risk on the trade while simultaneously maximizing their reward. When you begin to view each trade setup as just another execution of your trading edge and effectively implement position sizing and risk to reward scenarios, you will also be managing your emotions because you know your possible risk and possible reward BEFORE you enter the trade, you then set and forget the trade and therefore there is nothing to become emotional about.
