The three laws: supply and demand, cause and effect, effort versus result
The whole Wyckoff Method rests on three laws, and every event you will meet later is one of them in a specific costume. The law of supply and demand explains direction. The law of cause and effect explains size: a range builds a cause that an equal move spends. The law of effort versus result explains confirmation: volume should agree with price, and when it does not, something is changing. Learn the three laws cleanly and the schematics become obvious rather than memorised. This module draws each on gold and then reads them together.
Why three laws, and why they come first
Wyckoff reduced market behaviour to three statements general enough to apply anywhere yet precise enough to trade from. They are not indicators or patterns; they are the reasoning behind the patterns. Every named event later, the selling climax, the spring, the upthrust, the sign of strength, is one of these laws made visible at a moment. If you ever lose the thread in a complex range, come back to the three laws and ask which one the market is showing you now. That habit keeps your reading grounded instead of pattern-hunting.
The law of supply and demand
The first law is the familiar one: when demand exceeds supply, price rises; when supply exceeds demand, price falls; when they balance, price moves sideways. Wyckoff's contribution is to insist you read this from the chart itself, through the interaction of price and volume, rather than assume it. Rising price on expanding volume shows demand in control. Falling price on expanding volume shows supply in control. A sideways range is the two in rough balance while an operator quietly tips it. Everything else in the method is a way to see which side is winning before the move is obvious.
The law of cause and effect
The second law says moves are proportional to the preparation behind them. The sideways range is the cause; the trend that follows is the effect. A long, wide accumulation builds a large cause and tends to produce a large markup; a brief, narrow range builds a small cause and a modest move. This is why Wyckoff traders are patient with ranges: the time spent going nowhere is the market building the energy for the move. Module 15 turns this law into an actual target using a point-and-figure count, but the principle is here: bigger cause, bigger effect.
The law of effort versus result
The third law compares the effort, which is volume, with the result, which is the price range and progress. In a healthy move the two agree: heavy volume produces a wide bar and real progress. When they diverge, the market is telling you something. Heavy volume with little price progress means one side is absorbing the other, a warning of a turn. A wide bar on light volume can be a move with no conviction behind it. This law is the confirmation engine of the method, and Module 12 is devoted to it; for now, learn to glance from the bar to the volume and ask whether they match.
Reading the three laws together
The laws are strongest in combination. Supply and demand gives you direction, cause and effect gives you scale, and effort versus result gives you timing and confirmation. A classic read uses all three: a wide range builds a cause (cause and effect), volume dries up on the tests showing supply is exhausted (effort versus result), and price then rises as demand takes control (supply and demand). No single law is a signal on its own; the method is their intersection. When you evaluate any range, run all three questions rather than one.
The three laws on gold
Gold expresses these laws cleanly because it is liquid and news-driven. Expanding volume on a session-open thrust usually marks genuine supply or demand, not noise. Its multi-day consolidations are visible causes that precede the large directional runs the metal is known for. And its sharp, high-volume reversal bars are textbook effort-versus-result events, where a climax of volume fails to make further progress and price turns. Keep a volume histogram on your gold chart and you will see all three laws most sessions; the rest of the course is just naming where they appear.
FAQ
What are the three Wyckoff laws?
The law of supply and demand (price moves in the direction of whichever is in control), the law of cause and effect (the size of a range sets the size of the move out of it), and the law of effort versus result (volume should confirm price, and divergence between them warns of a change).
How is cause and effect used in practice?
The sideways range is the cause and the trend that follows is the effect, so a wider, longer range tends to produce a larger move. Module 15 measures the cause with a point-and-figure horizontal count and projects it to a target. The principle is that you should expect a move proportional to the preparation behind it.
What does effort versus result actually mean?
Effort is volume and result is the price range and progress a bar makes. When they agree, a move is healthy. When effort is high but result is small, such as heavy volume with price stalling, one side is absorbing the other and a turn is likely. It is the method's main confirmation tool.
Do I need volume data to use Wyckoff?
Yes, ideally. Two of the three laws lean on volume, so a volume histogram makes the method far more reliable. On gold, broker tick volume works well enough as a proxy for relative effort. You can read structure from price alone, but you lose the confirmation that effort versus result provides.
Which law matters most?
None alone; the method is their intersection. Supply and demand gives direction, cause and effect gives scale, and effort versus result gives timing and confirmation. A strong read satisfies all three, which is why the final checklist in Module 17 asks a question drawn from each.
