FTB-C000612 / Implementation concept

Same-Kind Level Clustering

Same-Kind Level Clustering is the policy of clustering high pivots and low pivots in separate populations.

Intermediate 1 linked topicEvidence-reviewed

Definitions

In plain terms

Resistance-like highs are not mixed with support-like lows in one density component.

Technical

DBSCAN neighborhoods are restricted to equal pivot kind before log-price distance is evaluated.

Scope

Mixing kinds can manufacture a level that has no coherent support or resistance meaning.

Examples

  • A reviewer computes Same-Kind Level Clustering on a small deterministic fixture and checks timing, units, and boundary behavior before publication.

Common misconceptions

  • Mixing kinds can manufacture a level that has no coherent support or resistance meaning.

Evidence and governance

  1. A Density-Based Algorithm for Discovering Clusters in Large Spatial Databases with Noise Ester, Kriegel, Sander, Xu · first party technical publication

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

    Limits: The original paper is not about financial support or resistance; that application is a package design.

  2. sklearn.cluster.DBSCAN scikit-learn · first party technical publication

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

    Limits: The package implements deterministic one-dimensional DBSCAN directly for Python/TypeScript parity.

  3. Pine Script pivot techniques TradingView · official platform documentation

    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.

  4. numpy.log NumPy · first party technical publication

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

    Limits: A log transform requires positive finite prices and does not by itself define a financial level.
