Three-Way Comparable Tests

Three-Way Comparable Tests is the shared normalized-spread test applied to all three triple-top highs.

Intermediate Formula defined 1 linked topicEvidence-reviewed

Definitions

In plain terms

All three highs must fit within one declared similarity band around their mean.

Technical

spread = (max(p1,p2,p3)-min(p1,p2,p3))/mean(p1,p2,p3) and the canonical limit is <= 0.025.

Scope

A third touch can expose an irregular range that a double-top test would have accepted.

Formula

spread=(max(p1,p2,p3)-min(p1,p2,p3))/mean(p1,p2,p3)
LaTeX: s=\frac{\max_j p_j-\min_j p_j}{\bar p}

Examples

  • A reviewer computes Three-Way Comparable Tests on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.

Common misconceptions

  • A third touch can expose an irregular range that a double-top test would have accepted.

    Supports: preferred label, short definition, technical definition, formula

    Limits: The package freezes its own equality, separation, and OHLC policies rather than claiming one universal pivot definition.
