Chan Bi Up Complete Guide

What is Chan Bi Up?

The 'Chan Bi Up' (Upward Stroke) is a foundational concept in Chan Zhong Shuo Chan (Theory of Chan), representing the smallest structural unit of a price trend. It signifies a bullish reversal or the initiation of a new upward move. A valid Upward Bi must consist of at least five K-lines after 'inclusion processing'—a method of merging bars where one is entirely contained within the range of the previous. It begins with a Bottom Pivot (Di Fen Xing) and terminates at a Top Pivot (Ding Fen Xing). The structural requirement of five bars ensures there is a clear separation between the low and high points, preventing minor market noise from being classified as a trend change. Unlike traditional patterns described by Thomas Bulkowski, which rely on geometric shapes, the Chan Bi is purely structural and mathematical. It signals that previous downward momentum has been neutralized and buyers have regained control. Volume typically expands as the Bi progresses toward the Top Pivot, confirming the strength of the move. While Bulkowski’s 'Encyclopedia of Chart Patterns' does not specifically categorize Chan Theory, the reliability of such structural reversals is often compared to 'Short-term Reversals,' which show a failure rate of approximately 20-25% in bull markets depending on liquidity. The pattern is highly regarded for its objective rules, removing the subjectivity often found in traditional candlestick analysis.

Identification Rules

1. The sequence must begin with a valid Bottom Pivot (Di Fen Xing) and end with a valid Top Pivot (Ding Fen Xing).
2. There must be at least five K-lines between the start and end, after applying inclusion processing to overlapping bars.
3. The high of the ending Top Pivot must be strictly higher than the high of the starting Bottom Pivot.
4. The Bottom Pivot and Top Pivot cannot share any K-lines; they must be distinct structural elements.
