From my experience, here are 4 reasons I discovered:
2/ Lack of knowledge—Inadequate understanding of the market, trading strategy, financial instruments, and fundamentals can lead to poor decision-making.
Yeah actually the lack of knowledge is the first thing that is leading so many people’s to lose their money in trading and instead of them to go and seek for knowledge before making decisions into trading they will not, but have a fundamental understanding about the trading and the inadequate market strategy will make you gain much profits when ever you trade.
3/ Not having a mechanical trading system—This leads to emotional trading. Decisions driven by emotions like fear and greed rather than rational analysis result in significant losses.
Anyone that is very emotional in terms of trading he will always results in ending of losing so much of their mom money in gambling, some people fear and greed is very strong when they come to trading and no none can what he want of he put the greed and fear in front, because what ever you comes to do your mind will be telling you that it will end of losing, and everything in this life start with the decision to try .
