This is where having a defined forex trading plan comes in; a trading plan will act as a guide which will keep you on the disciplined trading path. After the trade is over, make sure your trading plan includes an activity or some mandatory thing that you do after you have exited a trade, whether it was a winner or a loser. The best time to make your trading decisions is when you are not in any trades, this is done by creating a logical Forex trading plan that acts as your guide to the market, and this is really the only effective way to consciously make an effort at eliminating emotional trading mistakes.
