From the four-hour level observation, the price is operating in the lower band area of the Bollinger Bands. The rebound momentum during the afternoon is limited and has not been able to break through the pressure of the middle band. Combining the rules of the Bollinger Bands, the short-term weak pattern remains unchanged, and there is still a downside risk.

Switching to the hourly level, the three bands of the Bollinger Bands show a converging and closing characteristic, with both the upper band and the middle band simultaneously turning downwards, forming a short-term pressure slope. According to the principle of the Bollinger Bands 'band type guidance', convergence + the upper and middle bands probing downwards indicates a high probability of short-term market correction downwards. By pulling back to adjust the spatial relationship with the lower band, operations need to be cautious of price pullback risks and pay attention to the effectiveness of the lower band support.
