Overview
The Zanger Volume Ratio (ZVR) is a powerful indicator designed to reveal market dynamics by comparing current cumulative volume to an average determined over a historical look-back period. It uses the concept of relative volume to not only highlight unusual volume spikes, but also uses color to illustrate how today's trading compares to typical levels. This unique method of volume analysis was popularized by Dan Zanger - a trader known for turning $10,775 into $18,000,000 in less than two years - by identifying key shifts in market interest and volume behavior.
Key Features
Volume Pacing Analysis:
The script calculates a volume delta by comparing the cumulative volume at any given moment to an average derived over a user-defined lookback period (Default 20-day). The resulting percentage difference offers a clear visualization and insight into unusual volume activity.
Dynamic Visual Representation:
Choose between either “Columns” or “Area” plot styles to display the percent difference. Additionally, you have the option to switch between a standard plot or a background color display, with customizable transparency, ensuring the indicator fits seamlessly with your chart’s aesthetics.
Dashboard Integration:
A simple dashboard table is displayed on the chart, showcasing the current ZVR value in real-time. With user-configurable position, text size, alignment, and color options, this feature ensures that the key metric is always visible and easy to interpret.
Why Use the Zanger Volume Ratio?
The ZVR is more than just a volume indicator. It acts as a window into market sentiment by highlighting days when trading interest intensifies. Many traders believe that an unusually high volume ratio may confirm trend strength or signal a reversal, making the indicator a valuable tool when used in conjunction with other technical analysis methods.
Whether you’re monitoring stocks, commodities, or forex markets, the Zanger Volume Ratio offers an accessible yet sophisticated method to decode volume dynamics. Its practical design and real-time visual feedback provide traders of all experience levels with critical data to spot high-potential setups.

4C Volume w/ Relative Volume at TimeThis is a Volume indicator that also shows Relative Volume at Time (RVOL).
The RVOL is easily visible as a background color, that changes between Low and High RVOL colors.
The RVOL portion of the indicator is a modified version of the 'Relative Volume At Time' indicator by Tradingview (which has been the best/most accurate RVOL indicator i have seen yet on Tradingview, and seems to closely match the how the "Zanger Volume" indicator works).
Elevated RVOL can be a very important criteria for trading , especially on lower time frames.
This indicator can be used as a simple filter when looking at charts to determine whether it should be traded or not, based on the RVOL.
Higher volume/participation relative to previous time periods can lead to better follow through of moves and price action, and can lead to trending conditions.
Lower RVOL can lead to choppy market conditions, with lower participation and follow through on chart patterns.
The RVOL portion of the indicator draws from the Tradingview 'Relative Volume At Time' indicator developed by authors @e2e4mfck and @LucF , for TradingView.
This indicator takes the Past Volume mark and changes it into a background color.
High RVOL = When the day's cumulative volume is greater than the Past Volume levels, then the background is painted Blue by default
Low RVOL = When the day's cumulative volume is lower than the Past Volume levels, then the background is painted Purple by default
See annotated examples in the chart Below, which compares/contrasts this new indicator with the RVOL indicator by Tradingview:
Portions of the 'Relative Volume At Time' indictor code have been removed to clean up the script.
Plans in the future are to remove more code were possible, to further refine the script and speed up the processing times for the indicator.
If anyone is able to strip out more and keep it functioning the same, please let me know.
Enjoy.
