A quién sirve esta entrada — For anyone who reads charts but still interprets each bar in isolation. The three laws turn price and volume into three testable questions: who is in control now, how far price can move, and whether volume confirms or denies the move.
Fuente: the three laws belong to the teaching corpus of the Stock Market Institute and are formalised as «three laws» by the modern tradition (Wyckoff Analytics, StockCharts). In Richard D. Wyckoff's original texts the principles exist but are not numbered this way: the triad is a teaching synthesis, verified here against the Pruden & von Lichtenstein schematics (2006).

Why three laws and not one
The Wyckoff method starts neither from chart patterns nor from indicators: it starts from the premise that every price move is the visible residue of a clash between supply and demand, and that the clash leaves measurable signatures. The three laws are the three angles from which you read that signature. The first establishes the direction and strength of the balance at a given moment; the second establishes the stake, i.e. how much material has been accumulated or distributed and therefore how wide the following move can be; the third is the consistency check, the ongoing comparison between the energy spent (volume) and the ground gained (price range).
What separates Wyckoff from a naïve reading is that the three laws apply together, never in isolation. A breakout may look strong by law 1 (wide bar, close on the highs) and prove empty by law 3 (no volume): it is the cross-check that produces the judgement, not the single observation.
| # | Law | Variable read | Operational question |
|---|---|---|---|
| 1 | Supply and demand | Price, volume, position of the close | Who wins this bar / this rally? |
| 2 | Cause and effect | Width and duration of the range, P&F count | How much «load» has the range built? |
| 3 | Effort vs result | Volume compared with range | Is the move genuine or absorbed? |
1. Law of supply and demand
In plain terms — Price rises when buyers are more aggressive than sellers and falls when the opposite holds. Volume and the position of the close within the bar tell you how decisive that edge is.
The first law is almost tautological as stated — price moves in the direction of the imbalance between supply and demand — but it becomes operational when you stop treating it as an abstract economic principle and read it on the chart. Wyckoff does not measure demand by counting orders: he infers it from the joint behaviour of three elements. The range of the bar says how easily price moved; the volume says how much participation accompanied that move; the position of the close relative to the low and high of the bar says who had the last word in the session. A close in the upper third, repeated across several bars, signals that demand is absorbing every attempt to sell; a close persistently in the lower third tells the opposite story.
The real work lies in the comparison over time: rally against reaction. In a healthy uptrend, rallies have wider bars and more volume than the corrections that interrupt them; when the relationship inverts — reactions becoming more energetic than rallies — law 1 is signalling a transfer of control, what the method calls a change of character and which precedes phase changes.
Ejemplo — A stock advances with wide-range rally bars on 1.8× average volume, then corrects with narrow bars on half the volume: demand in full control. A few weeks later the same stock produces short rally bars on declining volume while the declines widen: supply has retaken the initiative, even though price has not yet broken anything.

2. Law of cause and effect
The second law introduces the method's most characteristic notion: the directional move (the effect) is proportional to the preparatory work done sideways (the cause). A trading range is not a neutral pause but the place where cause accumulates — the Composite Man buys or sells while the market stands still, and the duration and width of that range measure how much material has changed hands. The longer and wider the cause is built, the more extended the effect can be, given equal structural validity.
Quantification happens on the Point & Figure chart through the horizontal count: you count the width of the congestion at a chosen price level and project it vertically to estimate a minimum objective. It is essential to treat this number for what it is — a ruler, not a prophecy. Cause says how much potential has been loaded; if the structure is then valid (genuine accumulation and not masked distribution) the effect tends to meet or exceed the objective, but the count alone guarantees nothing.
The operational corollary is severe: an ambitious price target without a proportionate cause is wishful thinking. Anyone projecting a +30% target from a few days of range is ignoring law 2. Counting the cause and the distinction between bar-chart phases and P&F count phases are covered in detail in Cause count with P&F.
Ejemplo — A 14-week accumulation range produces a horizontal P&F count projecting +18% from the breakout point. That is a minimum objective consistent with the cause. The same stock, after three days of sideways action, does not justify any target of that magnitude: the cause is missing.

3. Law of effort versus result
In plain terms — Volume is the effort; the price range is the result. When effort is enormous and result minimal, someone is absorbing from the other side — often the Composite Man.
The third law is the control mechanism that keeps the other two honest. It compares the energy spent — volume — with the ground gained — the width and direction of the price move. When the two quantities are proportionate, the move is genuine: high volume and a wide range describe a market moving with no resistance from the other side. When they diverge, law 3 raises a warning. The most instructive case is high volume with a compressed range: enormous effort that produces no result means someone is absorbing all the pressure — the signature of institutional absorption at climaxes and in tests.
| Volume / range pattern | Wyckoff interpretation |
|---|---|
| High volume, narrow spread | Large effort, minimal result → absorption or trend exhaustion |
| Low volume, wide spread | «Easy» move — little resistance from the other side |
| Rising volume, decreasing price progress | Divergence — phase-change warning |
| Climax (SC/BC) | Extreme effort on one bar → often a phase reversal |
It is this law that gives meaning to climaxes: a Selling Climax is precisely maximum effort (record volume) with a limited net result (close far from the low). It also holds for the opposite, seemingly paradoxical, case: a valid spring breaks support on light volume — little effort, and price returns at once. There, law 3 says there was no supply left to absorb below support.
Ejemplo — After a long downtrend a bar appears with record volume and a wide downside range, but the close lands in the upper half of the bar. Maximum effort, modest net result: the typical signature of an SC in accumulation phase A. Law 3 anticipates here what the phases will confirm later.
The three laws as a system
The value of the method lies not in any single law but in their intersection. A spring, for instance, is credible only when law 3 (a break on light volume) operates inside a range that has built sufficient cause (law 2) and in a context where demand is objectively regaining control (law 1). The same spring on a stock in full markdown, with no cause behind it, is almost always a trap. Likewise, a P&F count objective (law 2) must be abandoned if law 3 shows the breakout happened without volume: the cause may be there, but the effect is not yet supported by demand.
Frequent mistake — Using one law alone to decide. A «nice» breakout (law 1) without volume (law 3) and without a measured cause (law 2) is the most common way to enter a false move late. Wyckoff judgement comes from the convergence of the three readings, not from a single convincing bar.
Summary card
| Law | Key variable | Operational output | Typical mistake |
|---|---|---|---|
| Supply/demand | Price, volume, close | Direction and strength of the balance | Reading the bar out of context |
| Cause/effect | Range width, P&F count | Minimum objective of the move | Target without proportionate cause |
| Effort/result | Volume vs range | Confirms or denies the move | Ignoring absorption on high volume |
