The biggest fear in trading is not understanding the trend. There are only three types: rising trend, falling trend, and wide range oscillation. Simply put, it is market sentiment. The market cannot keep rising or falling. In a long lasting market, the subsequent trend is mostly sideways and then starts to decline. If it is difficult to distinguish the subsequent ups and downs after a sideways trend, most of them will be dominated by trend lines. Breaking through can lead to chasing higher prices, while falling below can lead to chasing short prices. Strictly following the rules will greatly increase the winning rate. Blindly chasing the rise and killing the fall is the most terrifying thing, especially in a volatile market. If it rises, it will fall. What should you do if you chase too much, and if it falls, you panic and open short, only to see it rebound again? This is the most common fatal mistake that contract traders make.
