Yesterday's reversal analysis: The divergence around 1810 indicates a buy signal (second short-term weakening, which can be confirmed through interval overlays or multiple timeframes). The second buy at 1828, with a pullback point, forms a central oscillation after the second buy. A volume surge breaks away from the central oscillation, leading to a third buy (the pullback does not break the previous central high point). At this point, the MACD on multiple timeframes turns red, forming an upward shift of the central, indicating a strong trend.

Trend judgment point: The resistance level at 1975 shows no significant volume increase during the rebound. The pullback is small (the midline on the 5-minute chart remains unbroken), continuing the central trend. At this time, the US session volume surges upward, confirming the trend.

The price consolidates along the upper edge of the previous central (as long as the central is continuously formed and the line segments are not broken, the trend can continue upward). However, usually after the second central, divergence occurs with rapid upward movement, forming a trend divergence (creating three buy and three sell points). High-volume activity at high levels often results in gaps, which can only be identified through volume drops on minute or 10-second charts to confirm reversals.
