Who this entry is for — Readers who want to apply the Wyckoff tradition's three core questions without mistaking them for physical laws or automatic signals.
Wyckoff teaching organizes analysis around three “laws”: supply and demand, cause and effect, and effort versus result. Accessible modern sources present them as foundations of the method. The word law belongs to the tradition; it does not imply an invariant scientific relationship or a universally validated forecasting edge.
| Law | Observed data | Question | Output |
|---|---|---|---|
| Supply and demand | Price, volume, rallies, and reactions | Which side is more effective? | Directional hypothesis |
| Cause and effect | Trading range and Point-and-Figure count | What projection follows from the range? | Conditional objective |
| Effort versus result | Volume relative to price movement | Does effort produce a consistent result? | Confirmation or anomaly to investigate |
1. Supply and demand
In the Wyckoff framework, demand in excess of supply is associated with rising prices, while the reverse is associated with falling prices. The analyst does not observe the complete historical order book: they infer the balance by comparing price and volume bars, rallies, and reactions over time.
A sequence of broad advances and contained reactions may be consistent with more effective demand; the opposite relation may indicate greater supply. Close location and volume add context but do not have fixed meanings. A high close on heavy volume, for example, can reflect effective demand or intense trading near exhaustion; comparison and follow-through are required.
Comparison protocol
To avoid building a conclusion on one candle, the reading can be recorded in four steps:
- choose the timeframe and benchmark before observing the signal;
- compare rallies with rallies and reactions with reactions, not unlike bars;
- record spread, volume, close location, and cumulative progress;
- check whether the relationship persists in the next swing.
Example — Three successive rallies cover less distance while reactions broaden. This is consistent with less effective demand even though support has not broken. It is a deterioration hypothesis, not a forecast of a decline.
2. Cause and effect
The tradition calls work done inside a trading range the cause, and the later directional move the effect. It uses a horizontal count on a Point-and-Figure chart to formulate a price projection.
That projection depends on box size, reversal, count line, and range segmentation. It is not a guaranteed “minimum objective,” nor does it prove that a longer range must generate a proportional move. Its value is to make an estimate explicit and compare it with risk, structure, and support or resistance.
The modern count guide recommends using bar and P&F charts for the same range, locating the count point within the structure, and moving from a conservative count toward broader counts only as the move develops. “Phases” added to the count are complete counting segments and do not automatically match bar-chart Phases A–E. Documenting this distinction prevents the cause from being expanded retrospectively by selecting the most favorable columns.
Example — Two analysts can derive different projections from the same range if they use different Point-and-Figure settings. The procedure should document its parameters and count line instead of presenting the number as a certain property of the market.
3. Effort versus result
Effort is represented by volume; result by price movement. The comparison looks for harmony and divergence:
| Observed relation | Possible reading | Alternatives to consider |
|---|---|---|
| High volume, broad advance | Effort and result appear consistent | Climax, news event, gap |
| High volume, little progress | Possible absorption or opposition | Closing auction, composition change, liquidity |
| Low volume, broad move | Little opposition along the path | Thin market or wide spread |
| Less progress on rising volume | Possible loss of effectiveness | Non-comparable sessions |
No row is a standalone signal. A selling climax cannot be identified from record volume alone, and a spring does not always require low volume: structure, recovery into the range, testing, and later behavior all matter.
Two different cases — Very high volume on a down bar that closes well off its low may fit absorption, but AR and ST are needed to support a climax reading. A low-volume break of support followed by a prompt recovery may fit a spring, but the same move in a thin market can be liquidity-driven. The third law frames questions; follow-through separates the hypotheses.
Combining and invalidating the readings
The laws act as cross-checks. A breakout may show effective demand while the Point-and-Figure projection is inadequate relative to risk; a large count may exist without a confirmed exit; an effort/result anomaly may have several explanations.
Before acting, a reading should state:
- which evidence supports the hypothesis;
- what development would invalidate it;
- which settings produced the projection;
- what risk remains if the label is wrong.
Recurring errors
| Error | Why it is weak | Correction |
|---|---|---|
| “High volume means buying” | Every trade has a buyer and seller | Compare result, close, and later behavior |
| Choosing the target before the count | The count becomes a justification | Fix settings and count line in advance |
| One bar defines the balance | Supply/demand is a relationship over time | Compare complete swings |
| Divergence means a certain reversal | An anomaly can resolve without reversing | Require structure and invalidation |
The discipline includes preserving an alternative hypothesis. When evidence is mixed, “unclassifiable” is a valid conclusion.
