Cumulative Volume Delta
Cumulative Volume Delta is now an add-on
Previously, the Cumulative Volume Delta (CVD) was built into Bookmap as part of the Studies dialog. It is now available as a regular Bookmap add-on, allowing faster updates and easier management through the Add-ons Manager.
Cumulative Volume Delta Overview
Cumulative Volume Delta (CVD) shows the cumulative difference between buying and selling aggressor volume over time. It helps traders understand whether the market is dominated by buyers or sellers.
Interpretation
Traders use CVD to analyze the strength and direction of market pressure. A rising CVD indicates dominance of buy aggressors, suggesting bullish sentiment, while a falling CVD indicates dominance of sell aggressors, suggesting bearish sentiment.
Settings
The following settings are available for Cumulative Volume Delta:
- Symmetrical – Keeps the same amount of space above and below the zero line so that zero remains centered.
- Include 0 – Ensures that the zero value is visible but does not enforce symmetry.
- Compact – Adjusts the visible range dynamically based on the minimum and maximum values during the selected interval.
- Add CVD indication – Allows adding multiple CVD indications per symbol using the “+” icon.
- Minimum accountable volume size – Includes only trades equal to or greater than the specified size.
- Maximum accountable volume size – Includes only trades equal to or smaller than the specified size.
- Indicator range – Defines whether the calculation is based on the current chart range or the entire trading session.
- Reference points – Lets users define reset times and frequencies. CVD starts accumulation from zero at these points. You can also reset manually using the Reset Now button.
- Split buyers/sellers – Displays separate CVD indications for buyers and sellers.
- Colours – Sets display colors for positive and negative values. The eyedropper icon allows selecting any color from the screen.
