I think emotion is the greatest problem of a newbie trader. We all have gone through this while starting up but because of experience we can now discuss it as something not very serious but emotion is very serious and need to be put in perspective. One of the ways to work out the fears or emotion is to learn good money management. We fear of our emotion because we don't want to lose our money, so in the same light, if we use stop loss we will do better. However, this is difficult for a new trader to totally leave out emotion while trading because sometimes an experienced trader has same fear.
Perhaps, it was the greatest enemy for us but it is usually happen to newbies. This is one thing that we have to focus on how to manage well because even though we have gained a high level of knowledge and skill, and experience but still we can't manage to control this stuff, it was impossible to reach our goal. And I'd never find it difficult if we really wanted to succeed and have profitable trades. In fact, as we can see, a lot of people get into trading and fail and this is because of uncontrollable EMOTIONs.
Emotions are hard to resist because that’s part of being a human. And in everything we do, different emotions are always present. That’s why it’s difficult to control it even in trading especially if you are trading to make some profitable gains and to make your trades worth
