Support/Resistance Zone Strength and Decay Scoring

Install and import#

bash
npm install fintech-algorithms
ts
import { supportResistanceZoneStrengthDecayScoring } from "fintech-algorithms/geometric-chart-patterns/level-confluence-and-zone-scoring/support-resistance-zone-strength-decay-scoring";

Signature#

supportResistanceZoneStrengthDecayScoring(input)

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

Parameters#

NameTypeNotes
input{ source_confluence: number; zone_age_bars: number; half_life_bars: number; break_count: number; rejection_target_atr: number; touches: { age_bars: number; rejection_atr: number }[] }Record containing source confluence, zone age, decay half-life, break count, rejection target, and touch observations.

Returns#

{ state, score, grade, components, decayed_touch_evidence, touch_count }

One calculated score record with a bounded 0-100 score, qualitative grade, and every component contribution.

Errors#

  • When confluence, age, half-life, break-count, rejection, or touch input is outside its declared range — 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.
