Constructing an Elliott zigzag with ABC Fibonacci checkpoints

What a zigzag is

An Elliott zigzag is built as a three-wave A-B-C price sequence, not as a five-wave impulse. The zigzag is the ABC corrective form whose internals are counted 5-3-5, with B opposing A and C resuming the corrective direction after B ends.

In Elliott wave analysis, that form is an ABC correction: a three-leg countertrend construction labeled A, B, and C that is treated as a pause inside a larger-degree move rather than a new trend of the same degree. Elliott wave analysis is a price-structure method that labels market movement in nested impulse and corrective waves so a chart condition can be stated as a testable pattern.

Confirm the 5-3-5 internal count

In that construction, wave A is counted as five internal waves and wave B is counted as three internal waves. Wave B is defined as a move against the direction of wave A, and wave C is counted as five internal waves that begin only after wave B ends. That 5-3-5 internal count is the zigzag’s defining structure.

Fibonacci length checks on waves B and C

Fibonacci retracement is a ratio overlay on completed price legs that marks candidate turning zones from the length of a prior wave, commonly 38 percent, 50 percent, and 61.8 percent. Fibonacci ratio checks are applied to the A-B-C legs to mark candidate turning points while the zigzag is still forming.

The construction menu for wave B is a retracement of 38 percent, 50 percent, or 61.8 percent of wave A. The construction menu for wave C is wave equality, a length check that compares wave C with wave A and treats a 1.0 or 1.618 multiple of A as the two construction outcomes to monitor: equality with wave A, or a length of 161.8 percent of wave A.

Larger degree and the crowd checkpoint

The zigzag is classified as a correction of a prior wave of larger degree inside a market cycle. Crowd mood is used as a crowd checkpoint: a qualitative mood reading at each ABC turning point used only as a consistency test for the wave count, not as a forecast of results.

The checkpoint is subdued caution after A, optimism through B, then intense selling in C until pessimism peaks and the correction is treated as complete.
