Indeed, there are many TPS tips that have been shared on this forum, and quite a few have failed to be implemented. It must be admitted that it is very difficult to regulate emotions and psychology in investing, especially when it comes to fear and greed. But this is the most important thing in psychological science trading. No matter how great your technical knowledge is, your psychology is not strong.

So I think this first point is really very important in maintaining psychology.
