Real traders only care about two things:

1. How to act when the market proves I was right after I bought in;
2. What should I do if the market proves I was wrong after I bought in?
A qualified trader executes contract strategies in just one sentence,
Hold online, break the line and leave.
Every trade sets a stop-loss line, but won't easily take profit.
Learn to let profits run.
Every trade must set a stop-loss line, let profits run, but absolutely do not let losses run. There must be the 91 survival rule: out of 10 trades, if 9 are wrong but 1 is right, it can make up for the 9 losses. Every trade is a process of trial and error; trading is about finding the right direction among uncertain events. If you find the wrong direction, then stop-loss; do not have any illusions, and always maintain a sense of reverence.
A decline is a normal event.
The rise is an偶然事件.
The rebound is an unexpected event.
