Short-term contract players need to be aware of a trading rule: rapid declines or rapid rises after 8 PM on Sundays, especially on weekends, are basically traps;

This Sunday market is particularly suitable for left-side players. Even if one cannot profit from both long and short positions, they can at least gain profits in one direction. However, if one chases rising and falling prices, it is very easy to incur losses on both sides;

Therefore, do not use a right-side approach to chase rising and falling prices on Sundays; chasing rising and falling prices should be done after the U.S. stock market opens.
