mod note:
Zanger Volume tells you whether the move has real participation at this exact moment in the session.
The colors show how far above or below normal the volume curve is.
You don’t trade the color—you trade the setup, and the color tells you whether the setup has fuel.
Below is the code for the Zanger volume ratio that works. I can't take credit for it - it was generated by Claude. And Claude seems to have sourced some of its code from this community. This code mimics the ZVR found on TradingView. For it to work properly you will need a 5 minute chart with a time interval set for 30 days. I compared the results of this code to what I see with the ZVR indicator on TradingView and it does not match exactly but it works well enough for my purposes.
I hope this is helpful...enjoy.

How To Trade
- Structure first: Confirm there is Support, trend, VWAP reclaim, higher low, etc.
- ZVR color second
- Gray → skip
- Yellow → only trade A+ structure
- Violet → continuation is valid
- Magenta → breakout has real pressure
- Red → ignition; enter early or not at all
- Execution third: Your microstructure momentum/oscillator handles timing.

# Zanger Volume Ratio (ZVR) - Authentic Original Algorithm
# Direct port of the original eSignal ZVR by Fil (fl_zanger_volume_ratio_accumSTUDY.ts)
# sourced from usethinkscript.com thread #5093
#
# Methodology: For each of the 78 RTH bars, accumulates that bar's
# volume across all prior days, then divides today's cumulative volume
# by the average cumulative volume at that same bar position.
