• Maintain a range fluctuation between 155-160, waiting for market sentiment to repair. After breaking 160, observe the resistance at 186, take profits in batches, and adjust positions dynamically based on individual risk tolerance. It is crucial to focus on the effectiveness of the 155 support and changes in trading volume during the night. If holding a heavy position, it is advisable to prioritize risk control rather than pursue short-term gains. If the support at 153 is broken, it may accelerate the downward movement.
