Liquidity Gravity Map [PhenLabs]

• Composite Scoring Engine: Zones are not binary. They are graded on a 0-100 scale using 7 distinct metrics: Structure, Revisits, Wicks, VWAP Context, Mitigation, Decay, and Proximity.
• Dynamic Memory Allocation: Employs an internal memory cap (Max Zones) and a pruning algorithm to actively remove ancient, low-scoring zones, keeping the chart responsive and clean.
• VWAP Acceptance Context: Integrates Session VWAP and Standard Deviation bands. The indicator scores zones higher if their creation aligns with bullish VWAP reclaims or bearish VWAP rejections.
• Mitigation & Absorption Tracking: Dynamically evaluates how price interacts with a zone. It tracks volume, penetration depth, and displacement to quantify if a zone is being absorbed (defended) or broken.
• Time-Decay Function: Untouched liquidity zones lose their “gravitational pull” over time via an exponential decay function, prioritizing fresh liquidity.

• Zone Detection Algorithm: Identifies swing highs/lows and stop-hunt wicks, factoring in equal highs/lows clustering and wick ratios to establish initial structural strength.
• Session VWAP Engine: Calculates volume-weighted average price and its standard deviations over configurable sessions (RTH, Day, Week, Month) to gauge macro context and acceptance.
• Revisit Tracker: Monitors how many times a zone is tested. A zone’s score adjusts based on its frequency of testing relative to other active zones on the chart.

• Live Composite Score (0-100) dynamically updated per zone.
• Automatic culling of stale, irrelevant liquidity levels.
• Highly customizable lookback, zone sensitivity, and memory caps.
• Dynamic gradient coloring based on zone score (Bullish/Bearish).
• Toggleable Zone Labels displaying directional bias, score, and revisit count.

• Gradient Liquidity Boxes: Visualizes liquidity zones as shaded boxes. The opacity and color temperature (cool to warm) dynamically change based on the zone’s live composite score.
• VWAP Bands: Optional visual overlay of the Session VWAP and ±1σ / ±2σ standard deviation bands.
• Zone Labels: Small text labels attached to active boxes indicating “BULL” or “BEAR”, the “LG” (Liquidity Gravity) score, and “R” (Revisits).

• Lookback Period: (Default: 120) Determines the window for identifying stop-hunts and aging cleanup.
• Zone Sensitivity: (Default: 3.0) Controls the width of the generated zones and the tolerance for merging equal highs/lows. Higher values create wider, merged bands.
• Max Visible Zones: (Default: 8) The maximum number of top-scoring zones to render on the chart at one time.
• Score Decay Rate: (Default: 0.010) The exponential rate at which a zone’s score drops while untouched.

• VWAP Session Type: (Default: Day) Anchor period for the VWAP calculations (RTH, Day, Week, Month).
• RTH Session: (Default: 0930-1600) Defines Regular Trading Hours if “RTH” is selected as the session type.

• Color Theme: (Default: Classic) Choose between Classic, Neon, or Monochrome color palettes for the zone gradients.

• Identifying high-probability reversal areas for mean-reversion trading.
• Spotting areas where trapped liquidity (stop-hunts) is likely to act as a strong magnet for price.
• Filtering out weak support/resistance levels by relying on the composite score to highlight only structurally significant, defended zones.

• Rapidly changing volatility can cause sudden shifts in zone width, as it is dynamically tied to the Average True Range (ATR).
• Because the map limits the number of visible zones to the highest scoring ones, a valid but slightly lower-scoring zone might be hidden from view.

• Quantitative Liquidity Modeling: Most indicators draw static boxes at highs/lows. This script dynamically evaluates the “health” of a zone through continuous math—scoring penetration, volume absorption, decay, and VWAP alignment.

💡 Note: Ensure your chart data provides reliable volume data, as the absorption and VWAP scoring mechanics heavily rely on it for accurate calculations.
