I have a different concept when it comes to psychology, for me psychology is the same all the time, I even talked to a psychologist one day about the psychology of trading and he told me that it was nothing to write home about, that that was an invention to sell, the psychology is always the same, for trading as for sports, personality must be taken into consideration and how is its ability to solve problems in the event of a crisis, based on this it is that possible vulnerabilities.
For years I am saying that everything is gambling! It's the psychology or philosophy, take it as you like, we risk what we have to make more! Even everyday job is investing yourself (body, mind, and soul) to get some money! So it's simple, we invest what we have, it's our capital, bankroll, you name it... capital can be money, body, mind, and soul! In poker we would say, each of us gets the cards, how we will play it, it's up to us!
So whatever we do, whatever we are trying, we are gambling... we are risking what we have to make the profit! Of course, with more knowledge and experience we can minimize the risks, but nothing is risk-free in this world, in this life! And where is the risk, there is gambling!
Psychology is the same because the process is the same! We always risk (gamble) with something we have to earn more money! How we do it, and what works is another story to tell! But when you find something that works for you, something that pays off, you will do it as long as it last, and you will try to become better at that!
