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!
