Support & Resistance + Volume

This script is an advanced technical analysis tool designed to automatically identify institutional Support and Resistance zones, while analyzing the activity (Volume) within these zones. It automatically cleans up the chart to keep only relevant information.

Key Features:

Automatic Zone Detection:

Supports (Green): Identified based on major swing lows (Pivots).

Resistances (Red): Identified based on major swing highs (Pivots).

The width of the zones automatically adapts to market volatility (based on ATR) to remain relevant regardless of the timeframe.

Smart Merging:

To avoid cluttering the chart with overlapping lines, the script detects if a new support or resistance forms within an existing zone.

If so, it does not create a new box but expands the existing zone. This allows you to visualize consolidated "liquidity zones" rather than scattered lines.

Cumulative Volume Profile:

This is the core strength of this indicator. It calculates the total volume traded inside each zone since its creation.

Every time price revisits a zone, the candle's volume is added to the total.

Display: Volume is shown as whole numbers with a $ symbol (e.g., 300 500$) for precise reading.

Interpretation: A zone with very high volume indicates a strong battle between buyers and sellers, making the zone harder to break.

Historical Management (Broken Zones):

If the price crosses and closes beyond a zone (valid breakout), the zone changes appearance immediately.

It turns Gray, stops extending to the right, and the label displays the text "Cassé" (Broken). This allows you to keep a visual trace of past key levels without disturbing current analysis.
