The flow of short-term trading is limited, and short-term trading is like crossing a bridge. Once there are too many people carrying out a strategy at the same time, even if it does not cause resonance and cause the bridge to collapse, it will collapse due to the large number of people. The mid- to long-term trend is like everyone drinking from a river. If there are only three thousand people drinking from a river, everyone can have water. Although this also depends on the number of people drinking water and the amount of river water, which means there is a limit, the magnitude that can be accommodated is much larger.
