I have experienced a lot of sadness and disappointment because I lost a lot of accounts due to lack of discipline. I also realize that my main enemy is myself. I can not really blame the market because most of my mistakes are self-imposed. Now I try to slowly change my bad ways and discipline myself now or not at all and it's true. Discipline is very important in forex trading. we must learn to control ourselves and not violate our rules. because if we lack discipline, then we will lose in forex, so we have to practice and learn it. it's like ea, they are programmed to follow the rules and they are discipline.
