HVPro Style Indicator – Historical Volatility + Volume

HVPro Style Indicator is a combined volatility-and-volume tool designed to help traders visualize market expansion and contraction phases.
It calculates Historical Volatility (HV) using log-returns and a customizable lookback period, then smooths the result for a cleaner trend signal.

The script also includes a volume histogram, scaled by a multiplier, with bar colors changing based on whether volatility is rising or falling.
This makes it easy to spot moments when both volume and volatility align, often signaling trend transitions, breakouts, or exhaustion.

Features

✔ Historical Volatility calculation (annualized)

✔ Smoothed HV for cleaner visual trends

✔ Volume histogram with customizable multiplier

✔ Volume bar color shifts based on HV direction

✔ User-controlled visibility for both HV and volume

✔ Lightweight and optimized for all timeframes

How to Use

Rising HV (green volume bars) can indicate trend expansion or breakout momentum.

Falling HV (red bars) suggests contraction, ranging conditions, or volatility cooldown.

Watch for volatility shifts combined with volume spikes for potential trade entries.
