If you also have the situations described below, please identify yourself and think about how to correct and improve.
About losses and profits
Do not focus your trading efforts on avoiding losses, but rather on amplifying profits. Losses are inevitable, and you should view them as an unavoidable cost, just like commissions and taxes. While cutting losses is important, do not trade solely to avoid losses. Losses cannot be avoided, and losing trades can also be correct; traders must learn how to manage losses. The primary principle of successful trading is to cut losses and let profits run, but people often do the opposite. It is common for people to cash in small profits due to the fear that they will turn into losses in the future, exiting too early. On the other hand, people tend to hold onto positions that incur small losses, allowing them to develop into larger losses, clinging to the illusion that the market will reverse, hoping for a chance to break even later. This approach is exactly contrary to the principles of successful trading; traders should exit with small losses and hold firmly when there are floating gains.
Isn't it a straightforward feeling? 😏 Keep up the pace, and let you solve these problems.
