Volume Profile displays a per-price volume histogram for each trading session, built from real tick history — every tick lands on its exact price level, so you see where trading activity actually concentrated. POC and Value Area are calculated from volume. Designed to work standalone or side by side with the TPO Market Profile indicator.
Key Features:
- Real tick-data volume — exchange symbols (futures/stocks) use actual traded volume; forex/CFD symbols count one per quote tick at its exact price
- Automatic M1 fallback for sessions whose tick history is not downloaded yet, upgraded automatically once ticks arrive (Refresh forces it immediately)
- Mixed-feed protection — detects sparse trade ticks on quote-driven symbols and picks the denser tick stream, avoiding garbage profiles
- Daily & Weekly profiles with up to 50 historical sessions
- POC and Value Area (VAH/VAL) calculated from volume using the standard 70% rule
- Naked Levels — unvisited POC/VAH/VAL automatically extended to current price with price labels
- Anchor Session Right — bars grow leftward from each session's right edge, made to pair with a left-anchored TPO profile on the same chart
- Right Profile mode — anchors current session histogram to the right edge of the chart
- The developing session scales with elapsed time — the histogram never draws into the future
- On-chart control panel — toggle everything with one click, including hiding the whole indicator
- Auto row sizing — optimal tick-per-row calculated from session range
Requirements: Broker tick history (usually kept for weeks to months; first access downloads in the background) — complete M1 history is used as fallback. Recommended timeframe: M15–H1. Enable Chart Shift when using Right Profile.
How to Use
- Attach the indicator to any chart (M15–H1 recommended) and keep Use Real Tick History enabled
- On first run some sessions may use the M1 approximation while tick history downloads — they upgrade automatically; press Refresh to force it
- Classic combo layout: attach TPO Market Profile with defaults (Width Percent 50), then attach Volume Profile with Anchor Bars to Session Right Edge = true and Width Percent 30–40. Keep the two Width Percent values at 100 or less combined so the profiles never overlap
- Set History Count = 3–5 for intraday trading, 10–20 for swing trading
- Use Right Profile + Chart Shift to monitor only the current session
- With Weekly period + tick data the current session rescans the whole week every M1 bar — switch to Daily or disable tick data if the chart feels heavy
