Multi-Source Support/Resistance Zone Fusion

Install and import#

npm install fintech-algorithms

import { multiSourceSupportResistanceZoneFusion } from "fintech-algorithms/geometric-chart-patterns/level-confluence-and-zone-scoring/multi-source-support-resistance-zone-fusion";

Signature#

multiSourceSupportResistanceZoneFusion(input)

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

Parameters#

Returns#

{ state, zones, rejected_clusters, fusion_tolerance, minimum_sources }

One calculated fusion record with ranked accepted zones and reason-coded rejected clusters.

Errors#

• When levels are empty, identities repeat, source/price/weight fields are invalid, or fusion settings are invalid — throws

Complexity: time , space .

Worked example#

executed Captured by running this function on the input its own test provides. Real output of real code — but not asserted against a published figure.

The rest of the Level Confluence and Zone Scoring family#

• Price-by-Volume Profile ConstructionAggregates eligible point-in-time trades into deterministic tick-aligned price-by-volume bins.
• Point of Control, Value Area, HVN, and LVN DetectionSelects the point of control, expands a deterministic value area, and identifies local high- and low-volume nodes.
• Fibonacci Retracement and Extension ProjectionProjects declared retracement and extension ratios from a directed price leg and snaps every level to the nearest tick.
• Psychological Round-Number Level GenerationGenerates tick-aligned round-number levels inside explicit bounds and labels their salience and distance from current price.
• Support/Resistance Zone Strength and Decay ScoringScores zone strength from source confluence, decayed touches, rejection quality, durability, and break penalties.
• Support/Resistance Role-Reversal State MachineProcesses closes through active-role, break, retest, confirmation, and invalidation transitions for one zone.
• Breakout and Retest DetectionProcesses bars through breakout-pending, retest, confirmation, failure, and expiry states around one zone.
• Market-Wide Zone-Proximity Scanner and RankingFilters point-in-time zone records by proximity and ranks eligible instruments from proximity, strength, and freshness.
