Complete Interpretation of Chan Theory Trading System: A Comprehensive Operating Guide from Theory to Practice

The ChenLun (Chaintheory) reveals the true face of the capital markets, exposing human greed and fear without any concealment. As a complete trading theory, ChenLun is not simply a collection of technical indicators, but a rigorous logical system that encodes seemingly chaotic market movements into rules, allowing traders to identify genuine buying and selling opportunities within clear boundary conditions.

The Essence of ChenLun: Structuring Market Trends with Rules

Traditional market analysis often falls into subjective prediction traps, but ChenLun fundamentally changes this approach. Based on a thorough understanding of human nature’s greed, anger, and ignorance, it constructs a comprehensive set of rules—by encoding, it transforms disorderly market trends into an orderly structure, much like organizing a chaotic crowd into formations.

The core of this system involves two complementary processes:

Deconstruction: After a trend forms, as the time frame expands, the original trend continuously breaks down into smaller units—these are the same-level trend types. Through deconstruction, traders can clearly identify each buy and sell point, each opportunity and risk provided by the market.

Encoding: It converts the complex changes of market trends into standardized symbols and rules. Just like reading palm lines—each line has specific meaning, each turn has traces. This is the biggest difference between ChenLun and traditional technical analysis: it replaces subjective judgment with mathematical rigor.

Since everything follows rules, boundary conditions inevitably exist. These boundary conditions are signals of opportunities and risks, and also imply that all trends are quantifiable. This opens the possibility of building a complete quantitative trading system.

The Three Laws of Combination and the Central Concept: Mastering Market Rhythm

The theoretical core of ChenLun is based on three laws of combination. When a market trend develops to a certain extent, these laws make the possible completion of a trend “extremely clear and narrow,” meaning traders’ options are greatly reduced—from infinite possibilities to just a few outcomes. Mastering these laws is essential for solid trend judgment.

First Law of Combination: Containment Relationship
This is the most basic and easiest to operate. Adjacent candlesticks have containment relationships; simplifying these relationships can eliminate market noise.

Second Law of Combination: Stroke (Line) Combination Law
Strokes are the fundamental units of ChenLun analysis. Without understanding stroke combination, no application of ChenLun is possible. Strokes are composed of fractal patterns, which are made up of candlesticks, layered hierarchically.

Third Law of Combination: Trend (Trend Type) Relationship
This is the most subtle and artistic part. It defines the recursive relationship between trends at different levels and is the pinnacle of the entire theoretical system.

On the basis of these three laws, the most core concept is the Central. The definition of the Central may seem complex but is actually simple: it is the overlapping part of a trend type at a certain level, overlapped by at least three consecutive sub-level trends. For example, a 5-minute Central is formed when three 1-minute trend types overlap.

The Central has four modes of movement: formation, extension (oscillation not exceeding 9 sub-levels), rebirth (formation of a trend), expansion (oscillation exceeding 9 segments, upgrading to a higher level). Mastering these four changes allows insight into every shift in market rhythm.

Level Cognition: Operation Boundaries for Different Capital Sizes

The brilliance of ChenLun lies in solving a problem many traders overlook but is deadly—the significance of trend levels.

Many doubts about ChenLun stem from neglecting trend levels. Levels determine everything: direction, rhythm, risk tolerance, and position management. Major levels (yearly, weekly, daily) represent the big trend; smaller levels (60-minute, 30-minute, 15-minute, 5-minute) represent local details and minor trends.

Level determination is not arbitrary but depends on three factors:

Capital Size:
A capital of 1 million versus 10,000 differs not just in scale but also in the time cycle of intervention. Small capital can freely operate at the 1-minute level; large capital must wait until the daily bottom pattern forms and the trend is clear before entering.

Trading Style:
Aggressive traders prefer small levels; conservative traders focus on larger, more certain levels.

Risk Tolerance:
Systemic risk defines the lower limit of the levels you can operate within.

Once your operational level is set, your entire trading logic becomes clear: when the major level is upward, fluctuations at smaller levels are seen as oscillations and shakeouts. The strategy then is to hold positions (or coins). If technicals are mature enough, use small-level buy/sell points to lower costs and increase gains; if not, simply hold and wait for the major level’s sell signals.

Conversely, when the major level is downward, rebounds at smaller levels should be regarded as bear traps. Many losses come from traders being misled by small-level rebounds during a downward major trend, leading to frequent entries and exits, losing chips.

Divergence Signals and Fractal Judgment: Confirming Entry and Exit

If levels determine direction, then divergence decides the timing of reversals. A famous saying among ChenLun practitioners is: “Sell at divergence in high positions, buy at divergence in low positions—no prediction.”

What is divergence? It’s a weakening of trend momentum. In a continuous trend in the same direction, if the subsequent high creates a new high but with diminishing strength, it forms a top divergence. Conversely, if a new low is made with weakening momentum, it’s a bottom divergence.

Judging divergence requires meeting strict conditions:

First Condition: Confirm whether the trend is in a trend or consolidation. For consolidation, compare the strength of the ab segments; for trends, compare the bc segments. But divergence in bc segments does not mean the trend is perfect, as central shifts can create more central patterns.

Second Condition: Don’t rely solely on MACD’s green/red bars. Observe the yellow and white lines, especially the yellow line. When adjacent strokes within a segment show yellow-white divergence, it indicates genuine divergence.

Third Condition: The strength comparison of divergence must be obvious. Within the divergence segment, red/green bars should show a decreasing trend, and yellow-white lines should approach the zero axis, possibly crossing it.

Fourth Condition: Ultimately, confirmation must come from fractal patterns at the 1-minute level. This is the final verification step.

Fractals are the specific manifestation of divergence. Bottom fractals consist of three candlesticks, with the middle high and low points being the lowest; top fractals are the opposite, with the middle high and low points being the highest.

Fractals come in two types: intermediate and standard. The key difference is whether the fractal will generate a new stroke afterward. Usually, if a small-level trend shows consolidation divergence after the second buy/sell point, the correction is mild, and an intermediate fractal is likely; if no consolidation divergence occurs, the correction is larger, often resulting in a standard fractal.

Risk Grading Operation System: From Observation to Action

Knowing theory alone isn’t enough; ChenLun’s greatest strength is transforming complex trends into an executable operation system. The most ingenious part is risk level assessment.

Downtrend Risk Levels:

• ---- level (extremely high risk): Daily [-1,1] and Weekly [-1,1], any operation is like walking on a cliff edge
• — level (high risk): Daily [-1,1], Weekly [-1,0]
• – level (medium-high risk): Daily [-1,0], Weekly [-1,1]
• • level (medium risk): Daily [-1,0], Weekly [-1,0]

In practice, the more hyphens, the higher the risk. When encountering ---- level, even experts should prefer to wait and avoid trading.

Uptrend Risk Levels:

• ++++ level (extremely low risk): Daily [1,1], Weekly [1,1], should actively participate
• +++ level (low risk): Daily [1,1], Weekly [1,0]
• ++ level (medium-low risk): Daily [1,0], Weekly [1,1]
• • level (medium risk): Daily [1,0], Weekly [1,0]

More plus signs mean lower operation risk. In + level, even conservative investors should consider exiting or waiting for better opportunities.

Practical Level Selection and Indicator Coordination

Turning theory into practice, choosing the right level is crucial. For example, with a 30-minute chart:

• Enter on the 30-minute level after the end of a downward stroke
• Use the 5-minute trend type to judge divergence segments
• Find the first buy point on the 1-minute chart
• If missed, consider the second buy point
• Beware that the third buy point on 1-minute is very risky and rarely seen in weak markets

Pay special attention to the red/green bars and yellow/white lines on the 30-minute chart, as they frame the 5-minute and 1-minute trend types. If the smaller time frames are unclear, rely directly on the 30-minute’s indicators.

A practical tip is to look for “resonance points”—when multiple indicators signal at the same price level, often indicating a strong move. Combining with range trading can help pinpoint more precise entry points.

Moving averages also provide excellent auxiliary judgment. For example, the 5-day and 10-day moving averages:

• When the 5-day MA (female above) is above, it indicates a bullish trend
• When the 10-day MA (male above) is above, it indicates a bearish trend
  Their crossovers can be intermediate (continue current trend) or turning points. The safest entry is at the first pullback of the female-above crossover, representing the lowest risk entry point.

Common Mistakes and Breakthroughs in ChenLun Practical Application

Many traders learn ChenLun theory but face repeated setbacks in practice. These often stem from common misconceptions:

Mistake 1: Ignoring the importance of trend levels
Many treat levels as optional; in reality, they are the line between life and death. Without levels, there’s no clear direction; all buy/sell signals become meaningless.

Mistake 2: Viewing divergence as an absolute signal
Divergence has multiple preconditions. Seeing MACD bars shrink and assuming divergence appears is wrong. The phrase “diverged again and again, but divergence still exists” reflects a misunderstanding of divergence’s true nature.

Mistake 3: Chasing high gains in weak markets
In weak markets, a 30% rise can be quickly sold off by big players. Don’t believe in value investing nonsense. Risk control should be the top priority.

Mistake 4: Mechanical application of indicators
ChenLun emphasizes deep understanding of trend structures, not mechanical indicator use. MACD and moving averages are auxiliary; key is correct judgment of strokes, lines, and central patterns.

Mistake 5: Lack of multi-level linkage thinking
Don’t focus on a single level. Use multiple structures (weekly, daily, 30-minute) to observe, forming a three-dimensional operational advantage.

The true power of ChenLun lies in fundamentally changing how traders perceive the market. When you truly understand that “trends will eventually perfect,” prediction becomes unnecessary—you follow the actual trend. In this cycle of observation and decision-making, inner greed and fear gradually dissolve, leading to a transformation from losses to steady profits.
