Absorption Pro (Indicator)

1. Summary

Absorption Pro is a specialized Volume Price Analysis (VPA) tool designed to detect Institutional Intervention (Smart Money activity). It identifies specific candles where massive volume is traded but price movement is restricted ("Effort vs. Result" anomaly), signaling that a large player is absorbing the order flow.

The indicator visualizes these events not just as signals, but as Active Supply/Demand Zones that remain valid until the price breaks through them.

2. Methodology & Logic

The indicator combines volatility, volume, and candle structure to identify three specific market conditions:

A. The Signal Logic

1. High Effort: Relative Volume (RVOL) > 2.0. (Volume is 200% of average).
2. Low Result: Candle Body < 0.35 * ATR. (Price failed to move proportionally to the volume).
3. Direction: Determined by the Close position within the High-Low range.
   • Bullish Absorption: Close in the upper 66% (Buying absorbed the selling pressure).
   • Bearish Absorption: Close in the lower 33% (Selling absorbed the buying pressure).

B. The Climax Logic

• Condition: RVOL > 3.5 AND Body < 0.6 * ATR.
• Meaning: Extreme volume exhaustion. Often marks the exact top or bottom of a trend.

3. Visualization

• Arrows: Marks the signal candle immediately.
  • 🟢 Green Arrow: Bullish Absorption (Potential Bottom).
  • 🔴 Red Arrow: Bearish Absorption (Potential Top).
• Active Zones (Rectangles): Draws a shaded box covering the High/Low of the signal candle.
  • Dynamic Extension: The box automatically extends to the right into the future.
  • Breakout Detection: The box stops extending (terminates) the moment a future candle closes beyond the zone limits. This keeps the chart clean and shows only valid, untested levels.

4. Parameters

• InpATRPeriod: Lookback for volatility normalization (Default: 14).
• InpRVOLPeriod: Lookback for volume average (Default: 20).
• InpHistoryBars: How far back to scan for signals (Default: 500). Keep this reasonable to save performance.
• InpShowObjects: Toggle drawing of the Supply/Demand rectangles. (Buffers are always calculated).

5. Strategic Usage

1. Reversal Entry: If price approaches a support level and Absorption Pro prints a Green Arrow + Zone, it is a high-confidence reversal signal (Limit orders are active).
2. Breakout Failure (Fakeout): If price breaks out of a range but immediately prints an opposing Absorption signal, the breakout has likely failed (Trapped Traders).
3. Target Selection: The extended rectangles act as magnets. If you are in a trade, use the next active Absorption Zone as your Take Profit target.
