Reaction Weighted Support Resistance [Pineify] — Indicator by Pineify — TradingView

Overview
Builds ATR-scaled support and resistance zones from confirmed swing pivots. Opacity encodes decayed completed reactions and bounded relative-volume context. It organizes chart evidence without forecasting price or performance.

Problem Definition
A common baseline draws one line per pivot and adds strength for every return. It scores shallow drift and decisive rejection equally, while old tests can dominate after conditions change. The map becomes crowded, and counts do not explain what happened after contact. The required invariant is a bounded set of areas weighted by subsequent displacement, participation context, and recency without assuming repetition.

Design Rationale
Confirmed pivots replace immediate extrema; zones begin at confirmation, not at the earlier swing bar. ATR width replaces fixed ticks, but geometry is frozen from known volatility. Nearby same-side zones merge only under a height cap. Touch count was rejected: entry opens a finite window, favorable movement is normalized by touch-time ATR, and bounded volume adjusts credibility without claiming directional flow. Decay fades stale reactions. The tradeoff is lag in exchange for auditable path memory.

Key Features

• Confirmed pivot zones with ATR geometry.
• Completed reaction scoring, volume context, and half-life decay.
• Width-limited merging and bounded zone capacity.
• Close invalidation, strength opacity, optional visuals, dashboard, and alerts.

How It Works
The engine reads chart OHLC, ATR, and average volume. Confirmed pivot lows create support and highs create resistance. Width is a fraction of pivot-time ATR; signals are not shifted backward.

A same-side candidate merges only below the height limit. Its center is score-weighted, so weak evidence cannot freely drag an established zone. Otherwise it is added; capacity removes the weakest.

A completed entry after cooldown stores ATR and bounded volume credibility, then tracks the best favorable extreme. Support measures upward displacement; resistance measures downward displacement. The result is floored at zero, ATR-normalized, capped, and volume-weighted. Missing volume uses a neutral fallback.

Each completed bar applies half-life decay; a saturating transform maps score to opacity. A close beyond the zone and ATR buffer invalidates it. Warm-up needs ATR, optional volume average, and pivot confirmation. Unclosed bars do not mutate state or fire alerts.

How Multiple Indicators Work Together
The components form one chain: pivots supply location, ATR supplies scale, the path window separates reaction from touch, volume changes confidence, decay tests recency, and invalidation bounds life. Without the window this becomes touch counting; without decay old history dominates; without ATR markets lose comparable units. The boxes expose the combined state rather than stacking unrelated signals.

Trading Ideas and Insights
Compare areas instead of assuming they will hold. Opaque support means prior completed visits produced larger, more recent upward reactions under this model; resistance is symmetric. Observe approach, overlap, departure, and confirmed failure. Entry alerts focus review above the strength threshold, while invalidation ends stored context. They do not define direction, size, execution, return, or reversal probability.

Unique Aspects
Each touch creates a bounded episode whose later displacement, touch-time volatility, volume credibility, and age update one state. Merging is score-weighted and width-limited. Teal and rose encode role, opacity encodes strength, amber marks failure, and the dashboard exposes scores and evaluated touches. This is an independent implementation; retrieved descriptions defined only the baseline, and no source code was reused.

How to Use

1. Choose pivot lengths for the intended swing horizon.
2. Set width and merge limits so boxes remain useful areas.
3. Read opacity with score and evaluated touches; faint zones have little evidence.
4. Use alerts as review prompts with separate execution and risk rules.
5. Review several market regimes before using the context.

Customization
Short pivot windows create more candidates; long windows are selective and slower. Width and merge controls set geometry. The evaluation window favors immediate or slower reactions. Half-life controls memory, not signal speed. The invalidation buffer sets tolerated close penetration. Volume length changes its baseline; alert strength changes qualification. Secondary markers, bar colors, and dashboard can be disabled.

Assumptions and Limitations
Pivots are delayed. ATR gaps can distort geometry. Forex or synthetic feeds may supply tick volume or no usable series, so fallback removes participation discrimination. Favorable extremes summarize path outcome, not order flow, causality, liquidity, or execution. Results depend on settings; capacity can evict weak areas. Close invalidation can lag gaps, while intrabar penetration is insufficient. The model does not predict bounces, trade, model costs, or establish profitability. Non-standard and illiquid charts need separate review.

Conclusion
Prominence depends on completed, volatility-normalized reactions, bounded volume context, and recency. Evidence fades, geometry stays controlled, and confirmed invalidation ends the zone. Historical reaction remains inspectable context, not certainty.
