Delta Volume[integral]

Delta Volume [Integral] – Visualizing Accumulated Candle Dominance
This indicator measures and accumulates the net difference between bullish and bearish candle volumes over a user-defined range of bars. It integrates the volume dominance over time, offering traders a unique view into how buying or selling pressure has been distributed.

🔍 Concept & Logic
Delta Volume Calculation
For each bar, the script looks x to y bars back in time (e.g., from 10 bars ago to 5 bars ago) and:

Adds volume for bullish candles (close > open)

Subtracts volume for bearish candles (close < open)
This gives us a snapshot of volume dominance for that range.

What is Integration in This Context?
Integration, in this script, refers to the accumulation (summation) of these dominance differences over a period.

Much like integrating a function in calculus (i.e., area under the curve), here we are integrating the "net advantage" of buyers vs. sellers.

Over time, this builds a cumulative picture of directional pressure, showing whether buyers (positive integration) or sellers (negative integration) are in control.

Why It Matters

Unlike simple volume charts, this tool filters noise by focusing on who is dominating the market—buyers or sellers—and tracks that dominance over time.

It gives a macro-level view of pressure buildup, which can precede major breakouts or reversals.

📊 Visual Features
Buy Volume (green columns): Sum of volumes from bullish candles.

Sell Volume (red columns): Sum of volumes from bearish candles.

Candle Difference (white line): Net dominance difference (Buy - Sell).

Integrated Dominance Difference: Cumulative label showing the total buyer-seller dominance over the defined integration period.

Zero Line (dashed): Balance point.

🧠 Use Case
Detect divergences between price and cumulative volume pressure.

Confirm trend strength when integrated delta volume aligns with price movement.

Spot accumulation or distribution phases invisible on price action alone.

⚠️ If you're applying this to symbols with no volume data (e.g., certain Forex or indices), the script will stop with an error message.
