"A Trader's Mind"

Fear – Distress Over Losses: Psychologically, our minds process losses as more significant than a gain of the same amount. In trading, our fear of being wrong will often be used as a reason for staying in a losing position which leaves our accounts vulnerable to larger losses.
The most important part of trading is risk management. If you have a consistent and objective approach to risk management it will allow you cut your losses fast, and hold on to your profits!
Can you please explain more about risk management?
I would say that fear in trading is the lack of confidence in your actions and decisions, and you need to get rid of this more carefully by working and analyzing your approaches
Fear also often arises in those who have little experience, and this is natural, because, by gaining experience, we become more confident in ourselves.
