Reviewing the fluctuations near the close, a wide-range oscillation zone reappears, reaching the four-hour upper band resistance, and a long upper shadow is left by the spike.

Subsequently, it did not stabilize at the high point, and again deeply retreated below the middle band, with the Doko indicator showing good space.

From a cyclical perspective, the upper high of 9.0 is effectively solidified, and the support at 8.5 remains unchanged. The oscillation range is quite large; if not completely broken, it can continue to fluctuate within this zone.

Based on this view, a dip to 8.55-8.60 is expected, and stability can be seen in the 8.82-8.86 range.
