Triple-Bottom versus Double-Bottom Distinction

Triple-Bottom versus Double-Bottom Distinction is the distinction between two comparable low tests and three comparable low tests.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

A qualified third test routes the sequence to triple bottom.

Technical

Triple bottom requires three-way similarity and two peak anchors; double bottom requires two lows and one peak with a horizontal neckline.

Scope

Similar silhouettes do not make the detectors interchangeable.

Examples

  • A reviewer computes Triple-Bottom versus Double-Bottom Distinction on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.

Common misconceptions

  • Similar silhouettes do not make the detectors interchangeable.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: The curriculum does not prescribe this package's pivot window, numeric thresholds, causal state machine, or performance claim.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: The paper's smoothing, sample, and empirical design are not copied into this package and do not validate its thresholds.

    Limits: Platform display behavior does not establish financial usefulness or predictive value.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: This retrospective signal function is not itself a causal OHLC pivot detector.

    Supports: preferred label, short definition, technical definition, variant distinction

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