Emotion and online trading do not mix! Of course nobody likes to lose, but keeping your cool is a central key to your trading success. Do not allow a couple of losses to discourage you or a couple of wins to go to your head. Oftentimes we quit if we lose, which does not allow you to make back profit, or we overcompensate for a loss with a much larger trade. Neither of these will serve you well. \
Remember, consistency is key!
