From a technical risk perspective, the current price uptrend is facing resistance from the upper Bollinger Band, and during the rebound, trading volume has shown a continuous contraction characteristic, significantly reducing the bullish momentum. If a breakout above the upper resistance area cannot be achieved with a strong bullish candle, the price is likely to oscillate between the middle and upper Bollinger Bands tonight; if the bullish support remains weak during this oscillation, there is a possibility that the price may break down below the middle band support and retest previous lows. Based on a review of trading operations, previous bearish positions were successfully switched to bullish through timely strategy adjustments, ultimately achieving a turnaround from loss to profit. Given the current market structure, it is recommended to wait for the price to test the strong resistance level at the upper band before decisively establishing bearish positions, while setting the stop-loss above the key resistance level at the upper band, $BTC $ETH
