It is not easy to master emotions. It's about the maturity to think of a trader. There are only two things that I can convey the emotions of this mastery. First: the first practice to adhere to your trading plan. Into two: tradinglah only with money that is designated for your business. That is, do not trade with money that was originally going to use to meet daily needs, or the money that should be used to pay the bills. It also means you should not be in debt just for trading.
