Identification Rules

  1. The pattern must contain at least two distinct downward segments separated by a 'Zhongshu' (a consolidation zone with at least 3 overlapping bars).
  2. The second downward segment (the exit segment) must reach a price level lower than the first downward segment (the entry segment).
  3. The momentum of the second segment, measured by MACD histogram area or slope, must be lower than that of the first segment.
  4. A minimum of 20 bars is required to ensure the structural complexity of the central hub and the divergence segments are valid.

FAQ

How does Chan Beichi differ from standard MACD divergence?

Standard divergence only compares price and indicator peaks. Chan Beichi requires a 'Zhongshu' (structural hub) to exist between the segments, ensuring the comparison is between two trend movements of the same scale.

Quelle est la fiabilité historique de ce modèle ?

While specific 'Chan' stats aren't in Western literature, similar exhaustion patterns like Bulkowski's 'Three Falling Valleys' have a failure rate of around 15% in bull markets when confirmed by volume.

Le volume joue-t-il un rôle dans la confirmation d'un creux en Biseau Élargi Ascendant (Beichi) ?

Yes. A valid Beichi Bottom usually shows significantly lower volume on the second downward segment compared to the first, indicating a lack of selling interest at new lows.

Quelle est la meilleure période pour trader le creux de Chan Beichi ?

It is fractal and works on all timeframes, but it is most reliable on 1-hour or daily charts where the 20-bar minimum structure is less prone to market noise.

Quand le motif est-il considéré comme invalidé ?

The pattern fails if the price continues to drop sharply without a reversal, or if the 'Zhongshu' expands into a larger consolidation rather than leading to an upward breakout.
