The losing trader cannot tolerate the stress of a changing market. While focused on disaster, it is difficult to process useful information and to trade wisely. Stress also reduces the ability to make decisions. As the trader loses, anxiety intensifies, producing behavior that may multiply losses. The losing trader increasingly relies on others because of anxiety and cannot make independent decision.
Another response to loss is to repeat oneself, to make more of the same efforts rather than to step back and reassess. The losing trader keeps trading the same stocks in the same way. Reliance on memories of past trading experiences and remaining stuck in an old trading style keep one from seeing what is happening today.
