The short-term situation is complex with recent fluctuations forming a triangle continuation pattern, hitting a low near 2780. Currently, it faces resistance in the short term, and it is uncertain whether it will retrace to the 2800 level. However, there is optimism for a one-hour level rebound, with a focus on the 3100 level for the rebound; if broken, it is highly likely to initiate a new wave of four-hour level rebound. The key support below is at 2720; if it falls below this, it signals the end of the rebound. As long as it stays above 2770, this pullback remains within a reasonable range.
