Elliott Impulse Wave — what it is and how to use it in trading
Definition
An Elliott impulse wave is a simplified structural filter for an upward five-wave move, based on the classic rules of wave theory: wave 2 doesn't overlap the start of wave 1, wave 3 isn't the shortest of the motive waves, and wave 4 doesn't enter wave 1's price zone.
How it works in the builder
elliott_impulse_up/elliott_impulse_down are boolean operands with left/right parameters (confirming the intermediate swings the waves are built from). The signal is 1 on the bar completing wave 5 — once all five waves have formed and the structural rules hold. This is not a full, inherently subjective wave analysis — it's an honest, mechanical structural check.
What it looks like on the chart
On the chart an impulse is marked with five numbered waves (1-2-3-4-5) — three motive waves (1, 3, 5) in the direction of the trend and two corrective waves (2, 4) against it.
Typical use
A completed impulse is used to confirm that the trending move has run its course and a corrective entry should be sought, not as a standalone continuation signal. Typical condition: elliott_impulse_up == 1 as confirmation before looking for a corrective entry.
Common pitfalls
Classic Elliott wave analysis is largely subjective — different traders count the same waves differently. The builder's mechanical filter only checks the basic structural rules, with no alternate counts or diagonal triangles — a simplified but honest check, not a full wave count.
