Price Reaction Memory Heatmap

An open-source reaction-memory overlay: a confirmed pivot becomes a zone only after a qualified reaction of at least 2.00 ATR, and every zone then keeps its own history of distinct retests, penetration depth and post-touch reactions. Completed retests are classified as reinforced, neutral or weakened, time decays stale memory, and a 0–100 Memory Score (reaction quality 25%, freshness 20%, retest resilience 15%, zone integrity 20%, outcome evidence 20%) shows how much each zone still retains, until a confirmed close beyond the far edge invalidates it or its memory depletes.

Most zone tools are good at showing where price reacted and much less honest about what happened afterwards. A clean reaction area gets drawn once and keeps the same colour and weight after fifty bars, four retests and a wick through most of its depth. A tired zone looks exactly like a fresh one, so you give it the same trust.

Price Reaction Memory Heatmap treats each reaction as something with a lifecycle. A confirmed pivot (3 bars each side by default) only becomes a Memory Zone if price then moves at least 2.00 ATR away from it within 20 bars, and nearby or closely timed same-side zones are filtered out. From then on the zone records its own history: a touch counts only when price moves from outside to inside, penetration is measured against the zone's depth and capped at 100%, and the reaction after each touch is measured from the next bar, because OHLC cannot tell whether the extreme came before the touch.

Every completed retest is classified. A strong response with shallow penetration reinforces the zone, a deep penetration with a weak response weakens it, anything else is neutral. Age, retests, penetration and that accumulated evidence feed a 0–100 Memory Score in five bands: STRONG, ACTIVE, WEAKENING, FADING and DEPLETED. Badges show direction and score (✅ reinforced, ⚠️ weakening, ❌ fading). A confirmed close beyond the far edge structurally invalidates a zone, depleted memory retires it, and both are archived in grey rather than disappearing. Open-source and free, so you can read every rule.

From a blank chart to a read

1. Add Price Reaction Memory Heatmap to any chart with the default settings.
2. Read where a zone sits first, then its Memory Score badge.
3. Check its state: ✅ reinforced, ⚠️ weakening, ❌ fading, or plain for active memory.
4. Remember a zone appears only after its pivot confirmed and the reaction qualified. It was not known on the pivot bar itself.
5. Use the Memory Map panel to see how many active and strong zones are on the chart.
6. Filter by side or minimum score in Production Controls when the map gets busy.
7. Treat zones as context for your own analysis, and set alerts to monitor touches, reinforcements and invalidations.
