Long term operation emphasizes "reverse thinking", intervening at low prices and exiting at high prices. It does not require investors to have particularly ample time, nor does it require too much market analysis. All that is needed is for investors to have enough confidence and patience. When the market sentiment fades and there are many trapped investors, people become scared to talk about it. At this time, the price is very low, and everyone thinks there is no chance. The market trading volume is small, which is the opportunity for long-term investors to enter the market. Investors do not need to set stop loss points, only set profit points, and patiently hold trading orders. When the market is crowded and popular, it is the time for investors to achieve victory.
