FTB-C000624 / Data quality concept

Level Cluster Revision

Level Cluster Revision is the change to cluster membership or level output after a source or pivot correction.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

A corrected pivot can join, leave, or reconnect a density cluster.

Technical

Recompute affected same-kind neighborhoods and downstream cluster summaries after revisions; new pivots can also convert noise or border states.

Scope

Persist the input cutoff and algorithm parameters so a revised level can be audited.

Examples

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

Common misconceptions

  • Persist the input cutoff and algorithm parameters so a revised level can be audited.

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

    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

    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

    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

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