$ETH surged up and then quickly plunged; the bears have regained control of the short-term trading rhythm.

It has already broken below the middle band, and the rebound lacks strength. MACD has a dead cross turning downward; the green bars continue to expand, indicating stronger bearish momentum.

Bias is bearish in the short term. If 2430 breaks, look for 2400–2380; for now, it is not recommended to blindly bottom-fish!
