Level Confluence and Zone Scoring

9 algorithms in Geometric Chart Patterns.

In this family#

  1. Price-by-Volume Profile Construction contract

    Aggregates eligible point-in-time trades into deterministic tick-aligned price-by-volume bins.

    priceByVolumeProfileConstruction(input)
  2. Point of Control, Value Area, HVN, and LVN Detection contract

    Selects the point of control, expands a deterministic value area, and identifies local high- and low-volume nodes.

    pocValueAreaHvnLvnDetection(input)
  3. Fibonacci Retracement and Extension Projection contract

    Projects declared retracement and extension ratios from a directed price leg and snaps every level to the nearest tick.

    fibonacciRetracementExtensionProjection(input)
  4. Psychological Round-Number Level Generation contract

    Generates tick-aligned round-number levels inside explicit bounds and labels their salience and distance from current price.

    psychologicalRoundNumberLevelGeneration(input)
  5. Multi-Source Support/Resistance Zone Fusion contract

    Clusters nearby levels, computes deterministic zone centers, and separates accepted multi-source zones from rejected clusters.

    multiSourceSupportResistanceZoneFusion(input)
  6. Support/Resistance Zone Strength and Decay Scoring contract

    Scores zone strength from source confluence, decayed touches, rejection quality, durability, and break penalties.

    supportResistanceZoneStrengthDecayScoring(input)
  7. Support/Resistance Role-Reversal State Machine contract

    Processes closes through active-role, break, retest, confirmation, and invalidation transitions for one zone.

    supportResistanceRoleReversalStateMachine(input)
  8. Breakout and Retest Detection contract

    Processes bars through breakout-pending, retest, confirmation, failure, and expiry states around one zone.

    breakoutAndRetestDetection(input)
  9. Market-Wide Zone-Proximity Scanner and Ranking contract

    Filters point-in-time zone records by proximity and ranks eligible instruments from proximity, strength, and freshness.

    marketWideZoneProximityScannerRanking(input)

What they share#

Every topic here is a record-transform, so once you have called one the rest follow the same shape. Import paths differ only in the final segment:

ts
import { priceByVolumeProfileConstruction } from "fintech-algorithms/geometric-chart-patterns/level-confluence-and-zone-scoring/price-by-volume-profile-construction";
import { pocValueAreaHvnLvnDetection } from "fintech-algorithms/geometric-chart-patterns/level-confluence-and-zone-scoring/poc-value-area-hvn-lvn-detection";

Read them in the order above — the sequence is pedagogical, not alphabetical.

Where this sits#

Geometric Chart Patterns collects 27 algorithms across 4 families. For the concept behind this family rather than the call signatures, see the concept guides.
