交易中的负面情绪如何避免？

Fund management has always been a headache for me. May I ask you guys, how can I do a good job of position control?

I have had a few positions liquidated recently, but fortunately the losses were not very large. I would like to ask everyone, is there any way to prevent liquidation? Is there any trading discipline?

Why do many people in trading study Taoist or Buddhist theories?

What do you think are the core competitiveness of a good broker?

Are you happy doing business?

There is no such question, so I mention it.
