Candle heatmap

The candle heatmap replaces plain candles with candles painted by order flow. Each bar is a stack of heat cells - green where buyers were the aggressor, red where sellers were - and the brighter the cell, the more size traded there. It shows something a normal candle hides: where inside the bar did the volume actually print?

A chart using the candle heatmap - candles painted green/red by aggressor, brighter for more size

Overview

Where footprint gives you the numbers, the candle heatmap gives you the picture - the same buy/sell-by-price information rendered as colour so you can read a whole screen of bars quickly. A bright green band low in a bar is buyers stepping in at the lows; a bright red cap is sellers hitting the highs.

How to use

1. Open Chart Options and switch on the Candle Heatmap.

   

   Candle Heatmap settings - source, scale, sides, colors, line width

2. Choose a source and scale for what brightness means, then read the bars: the hottest cells are where the most aggressive volume traded.

Settings

Option	Values	What it does
Source	Volume / Large trades	Heat from total volume, or only the largest prints
Scale	Relative / Absolute	Normalize within each candle, or compare size across all bars
Sides	Dominant / Split	One colour per cell (winning side), or buy and sell shown side by side
Colors	Custom	Recolour the buy and sell heat
Line width	-	Thickness of the heat bands

Tip

Set Scale → Absolute when you care about real size - a faint bar genuinely traded less than a bright one. Use Relative when you only care about the shape of flow within each bar.
