[delta2win] Liquidity Zone Map

🔥 Liquidity Zone Map — Volume‑normalized pivot zones with adaptive ATR scaling

📊 What it does:
• Detects potential liquidity/liquidation zones above confirmed highs and below confirmed lows
• Draws dynamic zones whose height scales with ATR and whose color intensity scales with volume
• Zones extend right and terminate on rule‑based events (midline cross)

🔬 How it works (core formulas):
• Pivot detection: ta.pivothigh/ta.pivotlow with length L
• Zone height: H = max(ATR(T) × M, MinTicks)
• Intensity (volume‑normalized):
– Z‑Score mode: I = clamp((V − μ) / (σ + ε), 0..1)
– Piecewise mode: I = clamp(V ≤ μ ? V/μ : (V − μ) / (Vmax − μ + ε), 0..1)
• Gradient color: col = Gradient(I) (start → mid → end)
• Zone life‑cycle:
– Creation on new pivot (top/bottom)
– Right edge follows bar_index
– Termination when [low ≤ Mid ≤ high] with Mid = (Top+Bottom)/2, or optional TTL timeout
• Analysis range: global or constrained (Bars Back or ±% price window). Color scaling can be global or range‑scoped.

🆕 What’s new/different:
• Selectable volume normalization (Z‑Score or Piecewise)
• Timeframe‑adaptive ATR multiplier
• Range‑scoped vs. global color scaling
• Optional midlines, borders, info legend, scale legend
• Optional TTL termination for zones (lifetime in bars)
• Object management (cleanup/pooling) for performance

🧭 How to use (suggested presets):
• 1–5m: L=2, T=200, M=0.25, Range=Bars Back 1000, Intensity=Piecewise
• 15–60m: L=3, T=200, M=0.20, Range=Bars Back 1500, Intensity=Piecewise
• 4h+: L=4, T=200, M=0.20, Range=Off, Intensity=Z‑Score

⚙️ Settings:
• Pivot length L, ATR length T, multiplier M, MinTicks
• Opacity: base/auto (min/max)
• Range: Bars Back | Price Range ±% | Off
• Scaling: global vs. range‑scoped
• Midlines/borders/legends on/off

💡 Usage notes:
• Smaller L → more reactive, less robust
• Larger M → longer‑lasting zones
• On higher TFs, constrain "Bars Back" for performance

⚠️ Limitations:
• Non‑predictive; regime/volatility dependent
• Data quality impacts intensity computation

🚀 Update: Liquidity Zone Map — Optional Zone Removal on Hit

What’s new?
• Remove zones when hit (optional): New toggle to automatically delete zones once price crosses their midpoint.
• Default remains unchanged: when OFF, zones stop extending but stay visible for reference.

Why this helps
• Keep charts clean during high-volatility sessions
• Focus attention on fresh, actionable zones
• Maintain legacy behavior if preferred

How to use
1) Open settings → enable Remove zones when hit to auto-delete on touch.
2) Leave OFF to continue showing ended zones for context.

Notes
• This option is OFF by default.
• Works with all existing features: ATR-based sizing, volume-based coloring, analysis ranges, TTL, and optional midlines.

Changelog
• 2025-09-19: Added “Remove zones when hit” input (default OFF).
