Emotions when trading are quite dangerous. For example, you can make a good profit during the day and, succumbing to a second emotional impulse, lose everything in an instant. I've had that happen to me. That's why as soon as I feel that my emotions are getting the better of me I make a willful effort to turn off the computer.
Better to stop trading if we are emotion, it is not a proper situation to trade. I personally need to have a calm mind whenever I want to trade. Emotion may lead us to do something carelessly. It is too risky, trading isn't a safe place for emotional person. So, it is the right way that you turn of the computer whenver you feel emotionally.
This is why having more experience does really give out that kind of learning which would be enhancing out your emotions which would really be helpful into your career path.
Indeed. Experience makes us to have a better emotion management. Experienced traders/investors know well how to deal with their emotions when they are in profits or losses. It is important to have a good management for emotions, so we can still realistically at any situation.
