Opening Volume Scanner - Full Analytics

Opening Volume Scanner - Full Analytics
A volume analysis tool designed to identify unusual opening volume patterns by comparing bar volume to average daily volume (ADV). The indicator colors candlesticks when volume exceeds specified thresholds during the first bars of the trading session.
Core Functionality:
Monitors volume as a percentage of ADV for the first N bars from session open (default: 5 bars)
Colors bars across 4 progressive threshold levels (default: 5%, 10%, 20%, 50% of ADV)
Calculates ADV using a customizable period (default: 20 days)
Optional bullish-only filter to display only green bars that meet volume criteria
Volume Metrics:
Bar % of ADV: Current bar volume expressed as percentage of average daily volume
RVOL (Relative Volume): Bar volume divided by ADV (e.g., 5.0x = 500% of ADV)
30-Min Cumulative: Sum of volume for first 30 bars expressed as % of ADV
$ Volume: Bar dollar volume in millions or billions
Display Features:
Customizable data table showing real-time metrics (position, size, colors adjustable)
Optional $ volume indicator with 9 symbol choices (triangle, arrow, circle, etc.)
Progressive color coding: yellow/orange/red for increasing volume intensity
Green color scale for RVOL and cumulative thresholds
Alert System:
RVOL alerts at configurable thresholds (default: 5x, 10x, 20x)
30-minute cumulative alerts at configurable % ADV levels (default: 100%, 150%, 200%)
All alerts can be toggled on/off independently
Customization Options:
All threshold levels and colors are adjustable
Table rows can be individually shown/hidden
Background transparency and border options
Compatible with all timeframes (designed for 1-minute charts)
Use Case:
Identifies stocks experiencing unusual opening volume activity relative to their normal trading patterns. Useful for momentum traders looking for early signs of institutional activity or catalyst-driven moves in the first minutes of the session.
