# Precision Market Entropy Heatmap

Precision Market Entropy Heatmap paints volume distribution across every price level of each anchored session, computed from intrabar data for resolution the chart timeframe cannot show. Bright cells expose high-volume nodes and institutional interest, dark cells reveal liquidity voids, and a developing POC polyline tracks value migration live.

**Precision Market Entropy Heatmap** grades every price level of every session by how densely volume landed there, an [entropy](https://www.luxalgo.com/library/concept/entropy-measures/)-inspired read on participation, built from intrabar data rather than the chart timeframe. Each anchor interval becomes a block of cells: bright where the market did business, dark where it barely traded, plus a developing Point of Control polyline tracing value.

## How to Trade the Precision Market Entropy Heatmap?

- **Bright cells**: heavy volume concentration, prior agreement on value that often behaves as strong support or resistance.
- **Dark cells (liquidity voids)**: thin participation. Price tends to move fast through them, making them useful extension targets.
- **Developing POC slope**: upward supports bullish structure, downward confirms bearish conditions, value migration in real time.
- **Stretched price, flat POC**: deviation from the dominant volume node without value following flags overextension, a mean-reversion candidate.
- **Breakout validation**: a break out of compression earns trust once the POC shifts into the new range and holds.
- **POC extensions**: dashed lines carry prior value forward, green below price as potential support, red above as resistance.

Watching volume cluster, migrate, or vanish block by block shows where institutions are active and where price is likely to pause or accelerate.

## Precision Market Entropy Heatmap Settings

- **Anchor Interval**: the session length of each heatmap block.
- **Intrabar Precision**: the lower timeframe used for volume calculation. Finer is more accurate but limited by available history.
- **Number of Rows**: vertical price resolution per block; higher values cost more computation.
- **Max Sessions to Show / Extend POCs to Current Bar**: performance cap and forward extension of historical POC levels.
- **Show Developing POC**, gradient intensity, transparency, and POC color options shape the visual layer.

## Frequently Asked Questions

### How is this different from a standard volume profile?

A fixed-range profile compresses one span into a single histogram; the heatmap keeps time in the picture, showing how distribution evolved block by block. For node-level analysis of one range, [Volume Profile with Node Detection](https://www.luxalgo.com/library/indicator/volume-profile-with-node-detection/) is the natural sibling.

### Why does intrabar precision matter?

Volume at each price is reconstructed from lower-timeframe bars, so finer precision resolves levels the chart's own bars blur together. The cost is coverage: finer data spans fewer historical sessions.

### Is the Precision Market Entropy Heatmap free?

Yes, it ships in the free LuxAlgo Library, and Quant, our coding agent, can run it straight from this page. You can also copy the source code from this page and run it anywhere Pine Script® runs.
