Chanlun (Chan Theory), Explained — and Drawn For You
Chanlun (缠论), also called Chan Theory, is one of the most influential technical analysis frameworks in the Chinese-speaking trading world. It decomposes any chart into a strict hierarchy — strokes, segments and central zones — and classifies exactly where a trend can end. This page explains the full pipeline in plain English, and shows it drawn automatically on live crypto charts.
What is Chanlun?
Chanlun was written by an anonymous Chinese blogger under the name 缠中说禅 (roughly, Zen in the Entanglements) in a series of 108 lessons published between 2006 and 2008. The author died in 2008, leaving the series unfinished — yet it became a school of technical analysis with millions of readers, dedicated books, indicators and software in China.
Two ideas make Chanlun different from most Western technical analysis:
- Complete classification. Any market movement is exactly one of three things: an up-trend, a down-trend, or a consolidation. There is no fourth option. Instead of predicting what comes next, you observe which of the three the market is currently in — and how far along it is.
- Strict construction rules. Structures are not eyeballed. Overlapping candles are merged, turning points must qualify as fractals, strokes must connect opposite fractals, segments are built from strokes, central zones from overlapping moves. Two people applying the rules correctly should draw the same chart.
The building blocks
Chanlun processes a chart bottom-up through a fixed pipeline. Each layer is built only from the layer below it:
| English | 中文 | What it means |
|---|---|---|
| Containment | 包含处理 | Candles whose ranges engulf each other are merged into one, so that every remaining bar makes a strictly higher-high/higher-low or lower-high/lower-low step. |
| Fractal | 分型 | A three-bar turning pattern: a top fractal has the middle bar's high as the local maximum; a bottom fractal is the mirror image. |
| Stroke | 笔 | A line connecting a top fractal to a bottom fractal (or vice versa) with enough bars between them. The smallest meaningful swing. |
| Segment | 线段 | A run of at least three strokes moving in one direction, terminated only when a strict breakage rule is met. Filters out stroke-level noise. |
| Central zone | 中枢 | The price range where at least three consecutive sub-moves overlap — the battlefield where buyers and sellers agree to disagree. One central zone means consolidation; two or more non-overlapping zones in the same direction define a trend. |
| Divergence | 背驰 | The current leg of a trend covers new ground with visibly less momentum than the previous leg (commonly compared with MACD). Divergence is Chanlun's signal that a trend is exhausting. |
| Buy/sell points | 买卖点 | Three structurally defined locations where positions are classically taken. Every one of them is derived from central zones and divergence — never from a feeling. |
The three types of buy and sell points
Chanlun's best-known export. For a down-trend turning up (sell points are the mirror image):
- First buy point (一买). The final low of a down-trend, identified by divergence: price makes a new low below the last central zone, but momentum fails to confirm. This is the most aggressive entry — you are catching the turn itself.
- Second buy point (二买). After the first buy point, price bounces, then pulls back once more — and the pullback holds above the previous low. The trend structure has now visibly failed to continue down. More confirmation, slightly worse price.
- Third buy point (三买). Price breaks above the central zone, then pulls back — and the pullback holds above the zone's upper edge. The market has left the battlefield upward and defended it. This is the classic trend-continuation entry.
The three points chain across timeframes: a third buy on a higher timeframe is often, on inspection, a first buy of the next move on a lower one. That is why serious Chanlun practice is always multi-timeframe — the higher level sets the context, the lower level times the entry.
Why traders automate it
Everything above is rule-based, which is Chanlun's strength — and the reason drawing it by hand does not scale:
- Consistency. Containment and segment-breakage rules are exactly where manual charts silently diverge from the rules, especially in real time when the latest stroke is still forming.
- Workload. A proper read needs the same structure maintained on several timeframes at once — weekly for direction, daily and 4-hour for opportunity, minutes for timing. That is a full-time job per instrument.
- Hindsight bias. Structures look obvious after they complete. An engine that recomputes on every bar shows you honestly what was knowable at the time — including which strokes were still provisional.
ZenChart runs the full pipeline — containment, fractals, strokes, segments, central zones, divergence and buy/sell point classification — on live data, from weekly candles down to 1-minute, and redraws with every update.

Chanlun and crypto: a natural fit
Chanlun grew up on Chinese stock charts, but crypto is arguably a cleaner habitat for it. Markets trade 24/7, so structures develop continuously instead of gapping overnight. There are no daily price limits distorting the bars. And the liquid majors — BTC, ETH, SOL — produce deep, well-formed structures on every timeframe of the stack.
ZenChart streams major pairs in real time and computes the structure on each update; other pairs are analyzed on demand when you open them. For mobile, the same engine powers the ZenChart crypto app — full-screen Chanlun charts you can add to your home screen.
How is this different from indicator scripts?
There are Chanlun indicators for TradingView and MT5, and some are decent introductions. The structural difference: an overlay script approximates one or two layers (usually strokes and rough pivots) inside someone else's charting engine. A dedicated engine implements the whole hierarchy with the strict rules — segment breakage handled properly, central zones tracked as they extend and upgrade, divergence checked leg-against-leg, buy/sell points classified and revised honestly as bars close, across all timeframes at once with the levels linked.
If you are evaluating Chanlun seriously — especially in crypto where the market never sleeps — the difference between an approximate sketch and the full structure is the difference between decoration and information.

FAQ
Is Chanlun the same as Chan Theory?
Yes — Chanlun (缠论), Chan Theory and occasionally Entanglement Theory all name the same framework from the 108-lesson series.
Does Chanlun work on crypto?
Yes. It is a pure price-structure framework and applies to any freely traded market; 24/7 trading and the absence of price limits make crypto structures particularly clean.
Is ZenChart free?
Daily and 4-hour charts for major crypto pairs are free without registration. Minute-level timeframes and the multi-timeframe resonance panel are Pro features.
Do I need Chinese to learn Chanlun?
No. The concepts translate cleanly, and an auto-drawing chart removes most of the barrier — you can study the structure directly instead of decoding terminology.
Are buy/sell points trading advice?
No. They are structural classifications — a vocabulary for reading charts, not recommendations. Nothing here is financial advice.
