Here's a ridiculously simple market watching method: only watch from 9:30 to 10:00 every day, and you can judge whether to buy or sell that day. I’ve summarized it into six scenarios. Understanding them can help you avoid many pitfalls:

1. First rises then breaks below the opening price — main force is fleeing, follow and sell
2. First rises then falls but does not break the opening — retail investors are exiting, may rally in the afternoon
3. First falls then rebounds but does not surpass the opening price — retail investors are bottom-fishing, sell during the rebound
4. First falls then rebounds and breaks the opening — main force is entering, can follow and buy
5. Slight rise followed by sideways consolidation — main force is controlling the market, a trend reversal is imminent
6. Almost no fluctuation in half an hour — no main force, just watch the show

Remember these six points and use them with your trading strategy. It will greatly improve your market watching efficiency. There is no 100% accurate method in the market, but this half-hour in the morning often reveals the most genuine intentions of the main force.
