Wyckoff's Three Laws in Practice: Supply/Demand, Cause/Effect, Effort/Result
Apply Wyckoff's three laws to live charts with concrete tests for each law, including volume spreads and cause measurement rules for projecting effect size.
Wyckoff's three laws are not philosophy; they are diagnostic tools. Each law gives you a specific test you can run on a chart to determine whether smart money is accumulating, distributing, or absent. Applied mechanically, they cut through chart ambiguity.
Law 1: Supply and Demand. Price rises when demand exceeds supply and falls when supply exceeds demand. The practical test: on rallies, volume should expand and down bars should contract. If up bars show increasing volume and down bars show decreasing volume, demand is dominant. The reverse signals supply dominance. When up and down bars show equal volume, the market is in equilibrium and no trade is warranted.
Law 2: Cause and Effect. A consolidation (the cause) produces a subsequent trend move (the effect). The size of the cause determines the size of the effect. Measure the cause using point-and-figure horizontal counting: count the columns across the trading range, multiply by the box size and reversal (typically 3-box), and project that distance from the breakout. A 10-column cause at a 1-point box with 3-box reversal projects a 30-point move. Without a measured cause, you have no target.
Law 3: Effort versus Result. Effort is volume; result is price spread. When effort and result align—high volume producing a wide spread in the direction of the effort—the move is genuine. When they diverge—high volume producing a narrow spread or no progress—the move is stalling and a reversal may be near.
The effort-result test in detail.
- High volume + wide up bar: demand won, continuation likely.
- High volume + narrow up bar: effort present, result absent, supply absorbing demand, caution.
- High volume + wide down bar: supply won, continuation lower likely.
- High volume + narrow down bar: selling absorbed, potential bottom.
- Low volume + narrow bar: no effort, no trade.
Integrating the three laws. A tradable Wyckoff setup requires all three laws to confirm. In an accumulation range: Law 1 shows demand dominating (up bars on higher volume), Law 2 shows a sufficient cause (measurable range width), Law 3 shows effort producing result on the breakout (high volume with wide spread). If any law is absent, the setup is incomplete.
Common misapplications.
- Trading Law 3 (effort/result) in isolation without Law 1 confirmation. A divergence is only actionable inside a cause; in a runaway trend, divergences persist for long stretches.
- Measuring cause imprecisely. Guessing the range width produces random targets. Use actual point-and-figure counting.
- Ignoring Law 1 during a breakout. A breakout on declining volume violates Law 1 and usually fails.
The law sequence for entry. Confirm Law 1 (supply/demand bias) on the daily chart, measure Law 2 (cause) on the point-and-figure chart, then wait for Law 3 (effort/result) to confirm on the breakout candle. Entering before Law 3 confirms is anticipatory; entering after all three align is the Wyckoff edge. The laws endure because they describe how order flow translates to price—unlike indicators that repaint, they reflect accumulation and distribution mechanics unchanged since Wyckoff's era.
