#美联储回购协议计划 Bitcoin pulls back from highs, rapidly dropping from 88,500 to around 86,800 after spiking overnight. Ethereum weakens in tandem, and early long positions have been successfully taken profit on.

From the four-hour K-line perspective, $BTC broke through the middle line of the Bollinger Bands and faced resistance at the upper band, then pulled back. The resistance above is clear. Although there is short-term support around 86,100, the rebound momentum has significantly weakened, and technical bearish signals continue to accumulate—once the middle line is broken, the downward move will target the lower band key level. Maintain a bearish outlook.

Specific trading references: When $BTC rebounds to the 89,500-90,300 range, consider shorting with the first target at 87,300-86,500. If broken, continue to look lower toward 85,000. When $ETH rebounds to 2,990-3,030, consider shorting with targets at 2,910-2,780.

In the short term, market sentiment is relatively weak. The Federal Reserve's monetary policy expectations are still fermenting, and the adjustment pressure on risk assets continues. Keep a close eye on Bollinger Band dynamics and volume.
