Volume Profile█ VOLUME PROFILE
Volume-at-Price Analysis with POC, VAH & VAL
A powerful volume-at-price analysis overlay that calculates and visualizes the Point of Control (POC) , Value Area High (VAH) , and Value Area Low (VAL) directly on your chart. It reveals where the most trading activity occurred and provides real-time price position analysis — helping you identify high-probability support/resistance levels and mean-reversion zones.
Free and Open Source.
█ THE CONCEPT: WHY VOLUME PROFILE MATTERS
Price charts show when trading happened. Volume Profile shows where it happened. The distribution of volume across price levels reveals the market's true valuation zones:
Point of Control (POC) — The price with the highest accumulated volume. Acts as a magnet for price and the strongest single S/R level.
Value Area (70%) — The range containing 70% of all traded volume. Defines what the market considers "fair value."
Above/Below VA — Price outside the value area signals potential overextension or breakout.
Institutional traders, market makers, and algorithmic systems all reference volume profile levels.
█ CORE FEATURES
1. Volume Profile Engine
Distributes each bar's volume proportionally across the price rows it spans, building a precise volume-at-price histogram:
POC — Highest volume row = strongest support/resistance
VAH — Upper boundary of the 70% value area = resistance
VAL — Lower boundary of the 70% value area = support
Row count is configurable (10-50 levels).
2. Profile Anchoring
Three anchor modes control how the profile is built:
Rolling — Continuously recalculated over the last N bars. Best for real-time analysis.
Session — Resets every new trading day. Best for intraday context.
Week — Resets every new trading week. Best for swing context.
3. Price Position Analysis
Real-time classification of price relative to the value area:
ABOVE VA — Potential overextension or breakout
BELOW VA — Potential undervaluation or breakdown
AT POC — High-probability mean-reversion zone
IN VA — Normal trading range
4. Bounce & Rejection Signals
Automatic detection of price interaction with key volume levels:
POC Bounce Up/Down — Price touches POC and reverses
VAL Rejection — Price tests VAL and bounces up (bullish)
VAH Rejection — Price tests VAH and bounces down (bearish)
5. Volume Histogram Visualization
A horizontal bar chart displayed directly on the price chart showing the volume distribution. POC row highlighted with a distinct color.
█ AUTO-TIMEFRAME ADAPTATION
All parameters automatically adjust based on the chart timeframe:
1-5 min → Lookback 30, 18 Rows, Histogram Width 8
15-30 min → Lookback 40, 20 Rows, Histogram Width 10
1 Hour → Lookback 50, 24 Rows, Histogram Width 15
4 Hour → Lookback 70, 28 Rows, Histogram Width 18
Daily → Lookback 100, 32 Rows, Histogram Width 22
Weekly+ → Lookback 150, 40 Rows, Histogram Width 30
█ DASHBOARD
A compact, dark-themed info panel displaying:
POC — Current Point of Control price level
VAH / VAL — Value Area boundaries
Position — Current price position (ABOVE VA / BELOW VA / AT POC / IN VA)
To POC — Distance from current price to POC in percent
Anchor — Active profile anchor mode
VA Range — Width of the value area in price units
█ ALERTS (4 CONDITIONS)
POC Bounce Up — Bullish bounce off the Point of Control
POC Bounce Down — Bearish bounce off the Point of Control
VAL Rejection — Bullish rejection at Value Area Low
VAH Rejection — Bearish rejection at Value Area High
█ NON-REPAINTING
The volume profile is calculated from confirmed bar data only. Rolling mode recalculates the full lookback window on each bar using historical high/low/volume — no future data is used. Session and Week modes accumulate incrementally within the anchor period. No repainting.
