Elliott correction (A-B-C)

Corrections in Elliott Wave theory move against the trend in three waves, labeled A, B and C. The most common forms are the zigzag (a sharp correction where C goes beyond A) and the flat (a sideways correction where B returns near the start of A).

What it's for
  • Label a three-wave correction against the trend (zigzag, flat).
  • Anticipate where wave C could end (C = A, or C = 1.618 × A).

FormStructureShape
Zigzag5-3-5Sharp: B retraces a part of A (often 38.2–78.6%), C ends beyond A
Flat3-3-5Sideways: B returns to around the start of A, C ends near the end of A
Expanded flat3-3-5B exceeds the start of A, C goes clearly beyond A
Elliott A-B-C zigzag after an advance, with C ending below A
A zigzag after an advance: A falls 10 points, B retraces 61.8% of A, and C equals A in length, ending below the end of A. The low of C is the low of the correction.

How to draw it

  1. Choose Patterns → Elliott correction (A-B-C).
  2. Click the end of the prior trend (the start of A), then the ends of A, B and C.

Use a trend-based Fibonacci extension on A and B to project where C would equal A (level 1.0) or be 1.618 times A.

Limits

Corrections are the hardest part of Elliott analysis: they can combine into double and triple threes, and they often look like the start of a new trend until they end. Define the level where the corrective count fails (for a zigzag in an uptrend, a decline far beyond C = 1.618 × A points to a trend change rather than a correction).
