Profile Map

Paints every bar as a heatmap: level color = volume (Ask+Bid) or delta (Ask−Bid) at that price. Dense areas cluster into balance levels, with a histogram of demand and supply excess below.

The whole market as a heatmap: every bar painted by volume (cold→hot), dense areas highlighted as balance levels, and a histogram of demand and supply excess below.
WHY IT MATTERS
1
See where the volume really is

Every bar is painted by volume: dark is thin, bright is dense. Liquidity levels read at a glance — no manual markup.

2
Density = ready-made levels

Stable dense areas cluster into numbered balance zones — support/resistance for entries and stops, drawn from the real volume distribution.

See who's pressing

Delta mode and the excess histogram show whether buyers or sellers dominate at a level — and where the fuel for a move runs out.

KEY FEATURES
Profile heatmapEvery price level of a bar is colored by volume or delta — market structure is visible instantly, without manual markup.
Two modes: Volume and DeltaVolume (Ask+Bid) shows where the liquidity is; Delta (Ask−Bid) shows the buy or sell bias at each level.
Volume balance zonesDense areas are boxed with numbers and extended over time — support/resistance levels.
Excess histogramBelow the chart, buy excess (green) or sell excess (red) per bar — the imbalance between demand and supply.
3 normalization modesRelative · Absolute Auto · Absolute Manual — the color scale adapts to the instrument and timeframe.
Buttons right on the chartSwitch modes and period on-chart — no need to open settings.
Delta mode — the same map, but by which side dominates

Volume colors by volume (Ask+Bid). Delta (Ask−Bid) recolors levels toward the poles: green — buyers are pressing, red — sellers. Red hot cells at the top + a red excess bar below = a signal to reverse down.
Delta mode: which side dominates

The same map, but by delta (Ask−Bid): levels are colored toward the green pole (buyers) or the red pole (sellers). Red hot cells at the top + a red excess bar below = a signal to reverse down.

Below the candles — bars: green up = buy excess, red down = sell excess. An extreme bar near the threshold (gray line) = the fuel for the move is running out → look for a reversal.
Excess histogram

Below the candles, bars: green up — buy excess, red down — sell excess. An extreme near the threshold = the fuel for the move is running out, look for a reversal.

HOW IT WORKS
1Breaks volume down by level

In a sliding window, each bar's volume is broken down across price levels from Low to High (Ask+Bid at each level).

2Paints the heatmap

The more volume at a level, the hotter the color; the brightest cell = the level of maximum volume, a liquidity magnet.

3Builds balance zones

Continuous dense areas (volume above the filter) are boxed with a number and extended over time — support and resistance levels.

4Delta and the excess histogram

Delta mode colors levels toward the poles: green — buyers, red — sellers; the histogram below shows the demand or supply excess.

Anatomy of a bar's map: a stack of cells from Low to High — level color = volume (Ask+Bid) at that price; the hottest cell = the level of maximum volume, a liquidity magnet.
Anatomy of a bar's map

One bar is a vertical stack of cells from Low to High: level color = volume (Ask+Bid) at that price, and the hottest cell = the level of maximum volume, a liquidity magnet.

Hot cell — the level of maximum volume within the bar — a liquidity magnet (POC-like)
Cold levels — weak volume: dark/muted, often transparent after the filter
Green pole / buy excess — Delta mode — buyer bias; in the histogram — buy excess
Red pole / sell excess — Delta mode — seller bias; in the histogram — sell excess
Balance zone (box + №) — stable volume density = a support/resistance level

Bounce off a balance zone: at level #2 volume has accumulated across all bars (a hot band) — price approaches from below, hits the density and turns back up.
Bounce off a volume balance zone

At level #2 volume has accumulated across all bars — a hot band (a continuous volume zone, not a value area). Price approaches from below, hits the density and turns back up.

Trading bounces off volume balance zones

You want to enter off strong levels, but classic levels are drawn by hand and are subjective — it's unclear where volume has actually accumulated.

  1. Set the period to 20–40 bars and Volume · Absolute Auto mode
  2. Enable balance zones (Show Volume Levels), filter 150–200% — only the dense ones remain
  3. Wait for price to pull back to a balance zone on the heatmap
  4. Enter on a confirmed bounce, stop behind the opposite edge of the zone
Result: Your entry levels come from the real volume distribution, not from eyeballing; stop and target are tied to the edges of a dense zone.
