The core of trading is position management. All trading behaviors must be carried out in the appropriate position management. - Make big profits when you are right and small losses when you are wrong. This is the guarantee of stable growth of funds. - Because people always use emotions to determine rationality. No matter how you say that your decision is rational, it must be dominated by emotions. Your direction is subjective. All technical indicators will also have strong and weak tendencies because of your judgment. - We make money in the market. We should thank the market. It is not because we are so strong. It is because the market has made us taste the sweetness. Everything is chance and discipline that make us win. - The key is position management. Only by living long can you have the possibility of winning. - This is a probability game, not someone's ATM. - The difference between speculation and gambling is the difference between discipline and animality.
