We have recently discussed such a topic with a friend trader and came to one common conclusion that trading is necessary when you understand and feel the situation and see how you can get out of it if something goes wrong. For the most part, we use technical analysis, although our indicator sets are completely different. Plus, each of us has our own tricks, for example, I practically do not work with silver, because I constantly get into some questionable situations on it. But my friend does not trade even when there is a mega profitable situation with the franc, because once he lost half of his capital on it. And I think everyone has those moments, so the important thing is that your rules work for you..
