Practically all 'great' philosophers agree that free will, in the common understanding (the ability to make independent choices between different options), does not exist. Sooner or later, all of a person's actions are predetermined by their genetics, upbringing, socio-cultural environment, neural activity in different parts of the brain, etc. The only thing a person can do in their pursuit of freedom is to rethink, and ideally – to reject the averaged social morality and create their own. But such a person almost immediately becomes an outcast or even an enemy of society, including an enemy of their close relatives.
Even smart and educated people, who understand the futility of living by someone else's ethical norms, still continue to play this game. They simply lack the courage to go against the crowd, to give up their status. It is this flaw in human psychology (the limitless desire to appear as the most successful sheep in the herd) that prevents traders from consistently earning in the market. This is why almost everyone starts trading without training and with high leverage. Or based on someone else's signals, which is just absurd. Only a few can overcome this impulse (the desire to quickly gain recognition from the herd of their significance) – the socio-cultural conditioning of a person by society completely erases free will.
Although the mechanics of the market are actually very primitive and accessible for everyone to understand. Anyone could gather transaction statistics, write a trading system, and start earning on it. And all this in just a few months after training. But almost no one can, because it is incredibly difficult for people to conceive of their development outside the herd and live by their own rules.
The unsolvability of this problem (for the vast majority) also lies in the fact that even when a trader, after a year or two of losing trades, comes to understand the true reason for their failure (as was the case for me), they face another problem: where to find the motivation and strength to stay in trading, which in the near future will not yield any financial return. This phase can only be passed by convincing oneself that everything you are doing in the market now is for self-discovery and self-development. That the only objective criterion of your growth is positive dynamics over the distance. That even if you do not become a great trader, you will still become a great person who has overcome the primitive social incentives imposed by society.
Only with such attitudes will you have a chance to cultivate that very 'non-existent' free will for the ordinary people. This is what will allow you to make the right trading decisions.
Trading is a different way of life and a different way of thinking. Only those who came here to become a different person will succeed. Only those who are ready to devote several years of their lives to creating their own ethics can become professionals. All other random people who came to quickly make money will be chewed up and spat out by the market.
