In short
The core idea
Ralph Elliott noticed that markets don't move randomly but in waves that reflect shifts in crowd mood: optimism, doubt, optimism again. The basic model is an eight-wave cycle: five in the direction of the trend (the impulse) and three against it (the correction).
The character of each wave
- Wave 1 — the first move, which most people mistake for a bounce in the old trend.
- Wave 2 — a deep pullback; many are sure the trend hasn't changed.
- Wave 3 — the strongest and longest: everyone notices the trend and big money joins.
- Wave 4 — a sideways, sluggish correction; profit-taking.
- Wave 5 — the final push on crowd emotion, often with a divergence on oscillators.
- A–B–C — a correction of the whole impulse: a drop, a trap bounce, another drop.
Labelling rules
How to use it in practice
The most practical use is trading wave 3. It starts where the wave 2 pullback ends, usually in the 0.5–0.618 Fibonacci zone. Stop beyond the start of wave 1: if price goes there, the count is broken.
Waves are easy to label after the fact and hard to label in real time. If you keep relabelling the chart to make it "fit", the theory has stopped helping. Use it as a map of market phases, not as a precise forecast.
Common mistakes
Breaking the basic rules
If wave 4 enters wave 1's territory, it's not a "special case" but a wrong count.
Fading the fifth wave
A fifth wave can extend much further than expected.
Labelling every wiggle
Waves within waves go on forever. Work with one or two degrees of scale.
