Cumulative Delta Volume

CUMULATIVE DELTA VOLUME
This indicator is Cumulative Delta Volume (CDV), calculates bullish and bearish volume to determine whether NET BUY or NET SELL dominant within a user-defined bar range, helping traders clearly identify volume imbalance and directional conviction during market swings.

Additionally, this indicator calculates Average Price based on volume. Average Price represents the weighted price level where the level often acts as a dynamic support or resistance line:
- When price stays above the Average Price, it commonly functions as support, indicating sustained buying pressure.
- When price remains below it, the level often behaves as resistance, signaling dominant selling pressure.
- Reactions around this line can highlight potential trend continuation, rejection, or reversal zones.

The indicator also draws the high–low price range of the selected period, providing a clear visual boundary of the active trading zone. Combined with delta-based price levels, this helps traders understand where volume is being accepted or rejected by the market.

By merging volume, delta analysis, and price structure directly on the chart, Cumulative Delta Volume is a powerful tool for identifying smart money behavior, validating trend strength, and locating key support and resistance levels derived from real volume flow rather than price alone.
