Delta Volume Columns

The Delta Volume Columns indicator analyzes intrabar volume data to decompose each volume bar into its buying, selling, and neutral components. By using lower-resolution data within each chart bar, it provides a more granular view of market activity and buying/selling pressure compared to standard volume bars.

Usage

The indicator can be used to visualize volume distribution and identify imbalances between price action and volume flow. It offers multiple display modes:

• Volume Columns: Shows stacked columns representing buying (green), selling (red), and neutral (blue) volume.
• Volume Balance MA Delta: Displays the difference between the moving averages of buying and selling volume, often highlighting shifts in momentum.
• Relative Delta Volume: A normalized view of volume balance relative to historical averages.
• Divergences: Highlights bars where price direction and volume balance disagree (e.g., a green price bar with higher selling volume). These can be displayed directly on the volume columns or as highlights on the chart's price candles.

Details

The script uses the request.security() function to retrieve intrabar data. Because it relies on lower-timeframe information, the delta decomposition is only available for historical bars; the realtime bar displays standard volume until it closes. To ensure accuracy, the indicator checks if the chart's resolution is divisible by the selected intrabar resolution. Users can choose between automatic resolution stepping (for speed or precision) or a fixed manual resolution.

Settings

Display

• Color Theme: Adjusts column colors for dark or light backgrounds.
• Main Display: Selects between Columns, Volume Balance Delta, Relative Delta, or a combined view.
• Show Divergences: Enables visual markers for price/volume discrepancies.
• Realtime Mode: Enables a calculation mode for the active bar using price/volume updates.

Settings

• Intrabar timeframe: Sets the resolution for delta calculations (Fixed or Auto-Steps).
• Buy/Sell Volume Balance MA Period: The period for the volume balance moving average.
• Total Volume MA Period: The period for the standard volume moving average.

Markers

• Marker 1 (Double Bumps): Signals two consecutive bars with increasing volume in the same buy/sell direction.
• Marker 2 (Divergence Confirmations): Signals when a price move confirms a preceding volume divergence.
• Marker 3 (Volume Balance Shifts): Signals zero-line crossovers of the Volume Balance MA.

FAQ

• How do I access the Delta Volume Columns indicator? You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.
• Why does the volume column change appearance when the bar closes? The intrabar decomposition logic requires a closed historical bar to pull lower-timeframe data. The realtime bar shows standard volume until completion.
• Why is my chart background highlighted in red? This indicates a "Volume Discrepancy" where the total volume from the intrabar data doesn't match the chart's volume, often due to data feed differences at different resolutions.
