On the evening of December 27th, Bitcoin's recent rally just reached the target zone and then clearly showed signs of fatigue. According to the plan, I decisively exited at 236 points, then switched to a short position, ultimately securing a profit of 1388 points, with an unrealized gain of nearly 20,820 USD.

From the four-hour K-line chart, Bitcoin encountered obvious resistance after reaching a high at the top. The upper pressure level formed effective suppression, followed by a volume-driven decline. It has now returned to the lower boundary of the previous consolidation range. Judging from the K-line structure, the upward momentum has shifted from stagnation at high levels to downward correction. The middle Bollinger band has flattened and slightly turned downward, indicating that the trend's momentum is waning. The market has entered a phase of box-range correction and oscillation.

Switching to the one-hour chart, after continuous volume-driven decline, signs of shrinking volume and stabilization have appeared. However, the rebound strength is clearly insufficient, typical of a weak retracement after a decline. The short-term moving averages are still diverging downward, suggesting that this rebound is more about emotional recovery rather than a trend reversal. Based on the current rhythm, it is still advisable to sell on rebounds and follow the trend to short.

Short-term trading suggestion: Short Bitcoin around 88500-89000, with a target near 87000.
