$ETH The four-hour Bollinger Bands continue to narrow, forming a box-like oscillation structure, with the upper band slowly pressing down and the lower band slightly rising, indicating a temporary balance between bulls and bears. The current price is trading below the four-hour midline. After a previous surge to a peak, it has been steadily declining, followed by a long-term sideways range. Each rebound reaching around 1650 at the midline encounters resistance and falls back, unable to break above effectively. The overall oscillation center is slowly shifting downward, with selling pressure persisting above. In the larger cycle, resistance is concentrated around 1650, while key support at the bottom is at the 1581 level. The current price is in the lower middle of the oscillation range, with bears slightly favored. Repeated resistance at 1650-1658 suggests a priority to look for a pullback if that pressure is not broken.
