Many people are learning various techniques, drawing, indicators, or news... In fact, these are not the core of trading;
The core of trading is two points:
1. Mentality, a good mentality, not upset by losing money, not happy by making money, to put it bluntly, do not treat money as money;
2. Make big profits and small losses, lose small money when losing, and make big money when making money.
The core of trading is these two points, as long as you can do these two points, you can make money.
You think K-line is important, but there was no display in Livermore's era, not even K-line, and the prices were all reported by telegraph machines and copied on the blackboard. How did he make money?
Of course, if you want to make a lot of money, you also need a little courage.
Don't work hard in the wrong direction.
