Thank you for sharing your information and knowledge OP and I think some of the points you convey are true, but believe me these are just a few points that only refer theoretically and sometimes when we really get into trading we won't be able to easily control ourselves and think clearly to follow the advice. As you have said and conveyed because everyone has different influence factors and conditions.
As other members have said, the most important thing is that we really understand and know how to trade and find strategies that are suitable and comfortable for us to use. If we are tired or have a lot of thoughts, don't let us trade but we have to rest. If you experience a loss, don't give up easily and have to evaluate what went wrong after that let experience guide us to be better.
