Why the Central Hub You Draw Is Always Wrong

The central hub is the most fundamental and core concept in Chan Theory. But it is precisely this "fundamental" concept that countless people draw incorrectly.

01｜The Essence of the Central Hub

Central hub = The overlapping area of three consecutive sub-level trends.

Every student of Chan Theory can recite this sentence, but the drawings vary greatly. The problem is not "whether you've memorized it," but whether the sub-level division is correct.

02｜The Five Most Common Mistakes Beginners Make

Mistake 1: Treating strokes as sub-levels

The central hub is composed of sub-level trends, and sub-level ≠ strokes. Strokes are the smallest unit, but a sub-level trend contains at least three strokes, forming a complete "up-down-up" or "down-up-down" structure. Drawing a central hub with strokes is like building a building directly with bricks—you think you've constructed a house, but you're just stacking blocks.

Mistake 2: Including K-lines that are not within the overlapping area into the central hub range

The upper edge of the central hub = the lowest high among all highs in the three trends. The lower edge of the central hub = the highest low among all lows in the three trends. Many people's mistake: Seeing that two trends "seem" to overlap, they frame all the K-lines in between. The true central hub range is the geometric boundary of the overlapping area, not a visually "roughly similar" area.

Mistake 3: Ignoring the directionality of trends

The central hub emerges from consolidation, not from being "forced" into a trend. In an obvious upward trend, you cannot take the retracement part of "rise + pullback + rise again" as a component segment of the central hub. The prerequisite for the formation of a central hub is: two opposing forces repeatedly pull back and forth within a certain range. There is no true central hub in a unilateral trend, only a "central-hub-like structure."

Mistake 4: Mixing different timeframes

A central hub drawn on the 30-minute chart is not equal to a stroke on the daily chart. Many people use 5-minute strokes directly to piece together a "daily-level central hub"—this is not Chan Theory; it's a self-created theory. Each timeframe has its own central hub. Cross-timeframe analysis must use interval nesting step by step, and cannot jump.

Mistake 5: Drawing the central hub before the trend is complete

Constructing a central hub requires three sub-level trends to be completed sequentially. If you have drawn the central hub before the first pullback is finished, it's just your expectation, not the market's reality. The trend is complete in the end, and the central hub is also complete in the end. Without the third segment, there is no central hub.

03｜Three Steps to Drawing the Central Hub Correctly

Step 1: Confirm whether the sub-level is complete First ask yourself: Does the trend segment I've divided have a complete internal structure? At least see three segments of "up-down-up" or "down-up-down" to qualify as a proper sub-level trend.

Step 2: Find the overlapping range Take all highs from these three trend segments, and take all lows. Upper edge = the lowest high; lower edge = the highest low. The overlapping range = the central hub range.

Step 3: Wait for the third segment to emerge If there are only two segments, the central hub is still forming. Don't predict; wait for the market to show it.

04｜A Quick Verification Standard

Is there a "third-type buy/sell point" within your central hub range? If yes, your drawing is likely wrong. There is no third-type buy or sell within the central hub range—third-type buy must be above the central hub, and third-type sell must be below it. If a third-type buy "pops up" inside your drawn central hub range, the central hub is probably drawn incorrectly.

05｜Summary

Drawing the central hub—not too difficult, but not simple either. The difficulty lies in patiently waiting for the structure to complete; the simplicity lies in the rules being fixed.

Forget about "looks roughly similar" and let geometric boundaries speak. Whether the central hub is correct is not determined by feeling, but by structure.

"The trend is complete in the end" is not a comforting slogan; it is the most fundamental discipline in Chan Theory.
