12.15 Evening Review: Rebound is a signal to short; Whiteboard session yields six consecutive gains

The whiteboard market initially declines then stabilizes—early session bears push the price down to 87,500, then quickly rebounds to break above 90,000. In the afternoon, it enters a range-bound consolidation.

On the daily chart, the bullish trend shows decreasing volume with a positive close; last week's weekly candle recorded a bearish candle with an upper shadow. On the four-hour chart, the price touched the middle Bollinger Band and faced resistance, pulling back; the hourly chart also shows a decreasing volume bullish pattern, with the KDJ indicator gradually forming a death cross and diverging downward. The evening trading strategy is recommended to focus on short positions.
