Totally agree with you. You always need to control your emotions. And not only in trade, but in everyday life. Usually emotional actions create only problems. But it's very hard to give up emotions. But eventually it will turn out
i think it is not so easy to control emotions and specially in gambling where we most play gambling on our emotion, everyone invest their money in gambling to earn more money using shortcut way, but i think it is not such an easy job to earn money from gambling, in gambling you need to have a good luck and good experience and skill so as to make money.
Everyone has different emotional levels, so it's a bit difficult to suggest others to control emotions in our way. But in my opinion, controlling emotions in gambling is difficult if we do not set a target. Due to if lost in the bet then the sense of resentment and doubling bet will arise. But it's different if we have boundaries and targets, and decide to pause, This can also be done in trading .Thank you
