Currently, the big pie has also shown a V-shaped rebound, with repeated fluctuations between bulls and bears. Such roller coaster situations are only suitable for short-term trading; act quickly and secure profits to ensure safety.

In the afternoon, pay attention to 83700 for the big pie. If it cannot stand above 83700 at the 4-hour level today, then the overall rebound strength is not significant, and continue to pay attention to support levels around 82500-81500.

Conversely, if it stabilizes, look towards the upper resistance levels around 85200-86300.
