Short-term trading is not speculation; true short-term trading is an investment behavior that requires mastering certain market operation rules and a strong level of skill. Short-term trading actually tests a person's skills and patience. Those who excel in short-term trading must have looked at many candlestick charts, studied their trends, and summarized the general patterns.
In addition to reflecting short, medium, and long-term fluctuations, the most macro aspect of candlestick charts is that they can tell you which projects have good market value management and which projects have fallen after being dumped, merely harvesting retail investors.
