2. I don't know how to stop loss. I hope everyone will pay attention to this. If you find that the trend is wrong, stop immediately. Do not hesitate!
3. Never admit your mistake. Obviously, the trend is wrong, and you still don't stop to admit your mistakes. This practice is to admit your mistake at once.
Whether others are at risk depends on your analytical ability. Do less if you can't analyze, ask more questions and communicate more.
