From the current 1-hour K-line chart, a V-shaped reversal has formed in the trend, but there is an upper shadow near 88850, indicating that bullish momentum is gradually weakening, and there are signs of a potential peak forming in the short term. After the price touched the upper band, a pullback occurred, and it is currently retracing near the middle band. If it cannot stabilize, it is very likely to approach the lower band. Short-term overbought signs have appeared, and there is a technical demand for a pullback. It is advised to be cautious in chasing highs and to short on rallies.

Trading suggestion: When the price rebounds to the 88300-88800 area, a small position can be taken to short, with a target of 87000-86000.
