The most difficult part of learning to trade successfully is to make your mentality correct. In other words, learn to remove the fear of your trade.
We are not robots and this is not as easy as it seems. Humans naturally have emotions and you can not just turn them off. However, you can learn to trade in a way that you think about probabilities and, therefore, eradicate the feelings of your emotions when you exchange.
Once you have the right mindset, the rest will simply be put in place. After trading without success for 6 years, I changed it thanks to the change of my commercial mentality. I read some commercial psychology books and I have not looked back.
