Is there any psychologist who can help traders to train their sub-conscious minds and make decision-making more sharp and efficient?
I don’t think so; trading is something different. It is not a normal case that a psychologist can solve. This is all about the knowledge and understanding of trading, and if a trader knows the risk and every part of trading, then definitely he should maintain his peace of mind before he enters the market and starts trading, and if he can’t, then definitely that trader is not yet qualified as a trader; he needs to work on that before he trades.
The best professional there is to help you would be you.
Because others may only lead you to clues and to your final destination on the market.
Other things have to be done by yourself. And it will click to you eventually.
