Complete decomposition of trends — ambiguity and uniqueness

Today's Topic: Complete Decomposition of Trends — Ambiguity and Uniqueness

The core of Chan Theory is not prediction, but classification.

The phrase "Trend Perfectly Complete" is backed by a rigorous mathematical structure. Trends at any level are composed solely of two forms: trends and consolidations. And trends and consolidations are defined exclusively by the central zones.

This raises a key question: how should a segment of trend be decomposed to be considered "correct"?

The master of Chan explicitly states in the original text: The decomposition of a trend is unique, but this uniqueness is based on correct recursive rules. In other words, decomposition itself is multi-meaning, but once you establish the rules, the result is unique.

Understanding this is the first step to opening the door to Chan Theory.

The Source of Ambiguity

Ambiguity is not a flaw but a reflection of the market's essence. The multi-meaning of trends stems from three levels:

First, the difference in observation levels. The same segment of trend looks completely different on a 5-minute chart versus a daily chart. Someone might see a perfect third buy point on the 5-minute chart, but on the daily chart, it's just a swing within a central zone. Who's right? Both are right. Just perspectives differ.

Second, the choice of the starting point of a central zone. The starting point of a central zone can be chosen from the low of the first decline or from the subsequent rebound high. Different choices lead to different central zone ranges. Chan master says "The method of selecting the central zone is not unique," with the key being consistency—methods can vary, but switching back and forth within the same analysis is not allowed.

Third, the way trend types are connected. The end point of a consolidation trend often coincides with the start of a trend. This "coincidence" is a critical node for decomposition. Different analysts' judgments on this node are the largest source of ambiguity.

The Foundation of Uniqueness

Where does the uniqueness behind ambiguity lie?

It lies in the recursive rules of different levels.

Once you fix the following elements:

• The rules for the lowest level of segmentation (definition of strokes)
• The rules for constructing central zones (overlapping of three consecutive secondary trend segments)
• The rules for connecting trend types (alternation of consolidations and trends)

then, recursively from the lowest level upward, the decomposition of each level's trend becomes unique. In other words, rules are fixed, results are fixed.

This is precisely the confidence behind Chan Theory's "no prediction, only response"—not because you know what the market will do tomorrow, but because you know that regardless of how the market moves, you can decompose it clearly with the same set of rules.

Practical Techniques of Chan Theory: Multi-Level Simultaneous Positioning Method

Many traders' biggest confusion in practice is: even though the daily chart looks like it's going up, they buy in and it falls. Conversely, it looks like it's going down, they sell, and it rises.

The root cause is not analysis error, but misalignment of levels.

Core Principle: Buy and sell points are confirmed by subordinate levels

This is a repeatedly emphasized but often overlooked principle:

The buy/sell point at the current level must be a type/second-type buy/sell point at the subordinate level.

For example:

• The third buy point on the daily chart needs confirmation of a subordinate trend completion on the 30-minute chart.
• The third buy point on the 30-minute chart needs to find a corresponding trend completion signal on the 5-minute chart.

If you see a retracement on the daily chart near the upper boundary of a central zone and directly judge "the third buy point has appeared," you're likely to suffer losses. Because that move on the daily chart might just be a mid-segment of a subordinate trend on the 30-minute chart.

Practical Steps

Step 1: Define the level

Determine your operational level. If you're trading swing positions at the daily level, your focus should be on strokes and central zones on the daily chart. Don't try to find buy points on the 1-minute chart while operating at the daily level—that's self-contradictory.

Step 2: Simultaneous chart analysis

Open three charts: your operational level chart, subordinate level chart, and sub-subordinate level chart.

• Operational level chart: observe structural positions (central zone range, whether three types of buy/sell points appear)
• Subordinate level chart: check trend type completion (whether consolidation divergence or trend divergence appears)
• Sub-subordinate level chart: examine precise ranges (whether internal structures are complete)

Step 3: Wait for signal resonance

When all three levels point in the same direction simultaneously, the reliability of the signal greatly increases. Note the wording—it's not about "accuracy rate" but "reliability." The market has no accuracy rate; only the completeness of your response strategy.

Step 4: Set a bottom line

Any entry point must be bounded by the trend type at the subordinate level. When the subordinate trend type ends, regardless of profit or loss, you should exit and reassess.

Mindset Reflection

Transform judgment into response

The greatest pain for traders comes from the obsession with "must judge correctly."

Once you accept the fact that "trend decomposition is ambiguous," you'll realize: the same trend segment can lead to different conclusions under different analytical frameworks. This does not mean someone is right or wrong; it just reflects different perspectives.

A truly mature trader is not someone whose judgments are more accurate than others, but someone who responds more comprehensively.

You don't need to worry about "whether this is consolidation or trend," only ask yourself three questions:

1. If it consolidates, what is my strategy?
2. If it trends, what is my strategy?
3. If it reverses, what is my strategy?

When your strategies cover all possibilities, you no longer need to "guess correctly." You only need to ensure "no matter how it moves, I have a response."
