The most important rule, which always helps in trading, is to keep statistics. And it is necessary to record not only profit and achievements, but also assets that have been used today, strategies, time, failures and so on. Maybe it sounds too difficult, but just when I started to adhere to such a system, success and stability came to my trading. And to be honest, I am ready to spend a lot of time on it, the main thing is to make money. By the way, as far as I know, a lot of traders also control the statistics in order to analyze the periods when it turns out better and when it turns out worse.
