You must memorize your own trading system!
Execute according to your own trading system, and even if you make mistakes, I won't regret it because I haven't violated any rules; I followed the trading system. In this case, you need to refine, correct, and optimize your trading system. Once the trading system has been optimized and solidified, the probability of making mistakes will decrease.
You can emulate my trading system to create your own unique trading system. We have different personality traits and financial situations, so our trading systems will differ; this is completely normal, as different people require different trading systems. Once your trading system is formed, be sure to print it out or write it in a notebook, and whenever you have time, read it aloud, memorize it, and write it from memory. The purpose of this is to reinforce your memory, allowing the trading system to become second nature and enter your soul.
