Anchored Volume Profile
- Indicators
- Version: 3.41
Short description
Right-anchored, flicker-free Volume Profile with POC/VAH/VAL lines, tick-throttled updates, and zero measurable lag even on fast, high-volume symbols.
Full description
Anchored Volume Profile draws a fixed-range volume histogram from a chosen
start date through to the live, forming bar — pinned to the right edge of
your chart like the panels in TradingView, and built to stay smooth even on
fast-moving, high-tick-volume symbols.
KEY FEATURES
- Fixed-range profile anchored to any start date (or an automatic rolling
window), rebuilt only when it actually needs to be — not on every tick.
- Point of Control (POC), Value Area High (VAH) and Value Area Low (VAL)
drawn as dashed rays starting exactly at your anchor date, with live
labels that track them.
- Optional up/down volume coloring per bin, so you can see buying vs.
selling pressure at each price level.
- Zero-volume "void" bins are marked with a thin hairline instead of being
left blank — useful for spotting unfilled FVGs / liquidity voids.
- One-click show/hide toggle button, and an optional auto-fit of the
chart's right margin so price sits flush against the panel.
- Fully configurable panel position, bin count (10–400), colors, fonts,
and Value Area percentage.
BUILT FOR PERFORMANCE
Earlier volume-profile panels can bog down the whole terminal on fast or
high-volume symbols because they redraw and recompute far more than they
need to. This indicator only pays for what changed:
- A full historical rescan runs solely on load, on a genuine breach of the
profile's price range, or after a detected data gap — never on an
ordinary bar close.
- The forming (current) bar updates incrementally and is throttled to a
configurable interval, so a burst of many ticks per second can't spike
CPU usage, while still guaranteeing no volume is ever silently dropped
at bar close.
- Chart objects are only rewritten when their on-screen position or color
actually changes, and the chart is only redrawn when something moved.
- All price-to-pixel positions are derived by fast linear interpolation
from two reference points per frame, not one lookup per bin.
The result is a panel that stays accurate and responsive without adding
noticeable load to your terminal, even with many charts open at once.
INPUTS
- Anchor: start date, number of bins (10–400), Value Area %
- Panel position, size, and margin auto-fit
- Colors for normal/value-area/POC bins, up/down volume, void hairlines
- POC/VAH/VAL line and label toggles
- Toggle button position and size
- Performance: tick update throttle, redraw throttle, large-anchor warning
threshold
- Instance ID, for running more than one copy on the same chart
Works on any symbol and timeframe. Recommended for traders who use
Volume Profile / Market Profile concepts (POC, Value Area) as part of
their price-action or order-flow analysis.
