Median Cluster Level

Median Cluster Level is the median price of pivots assigned to one support or resistance cluster.

Definitions

In plain terms

The median gives a central descriptive level without letting one extreme member dominate as much as a mean.

Technical

level = median({p_j : j in cluster}); its unit is the positive price unit of the input basis.

Scope

The median is an observed summary, not a prediction interval or guaranteed barrier.

Formula

level = median of member pivot prices
LaTeX: \widehat p_{level}=\operatorname{median}\{p_j:j\in C\}
SymbolMeaningUnit
Ccluster member setset

Output unit: price

Examples

  • A reviewer computes Median Cluster Level on a small deterministic fixture and checks timing, units, and boundary behavior before publication.

Common misconceptions

  • The median is an observed summary, not a prediction interval or guaranteed barrier.

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, formula

    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, formula

    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, formula

    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, formula

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