When I started trading , in my mind always I was getting negative thoughts (or thoughts which made me to reverse my decision)
You had negative thoughts because you did not do the necessary research and you did not know the terrain you were dealing with. When the person has vast knowledge of the thing that is going to invest and the person does not invest money that can not afford to lose, the person does not panic every day and the person is not afraid and does not have negative thoughts. You do not need meditation, you need knowledge and invest money that you can afford to lose.
I saw a article about trading psychology where he had mentioned that before stating trading do meditation for few months as it really changes the way of your trading
and how would that meditation be? I still think people do not need it, people need knowledge and money they can afford to lose.
