Trading is a complicated subject which is not able to bring profit to everyone. Just as there is a history of gains in trading there is also a history of losses. Successful application of knowledge skills and statistics and successful application of control is a prerequisite for success eliminating all types of mental instability. See everything in life is difficult if it is associated with unattainability. But there must be a plan in trading and it must be in a controlled way because if there is no control in the profit plan it will make us lose.
It's true that not everyone will be able to make a profit from the trades they make, but if they can do it well, of course they will be able to make a profit on the trades they make and what you say is very correct, you need skills in trading to be able to make a profit from the trades you make because without skills and experience it is certainly difficult for someone to be able to make decisions that benefit them in trading so they continue to experience losses if they trade without good skills and knowledge, yes of course we have to focus on the planning we have made and after achieving the target what we have determined is that it would be better to take the profits we have obtained so as not to become greedy which makes us lose the profits we have obtained.
