# Volume Grid Heatmap Volume Grid Heatmap spreads traded volume across a two-dimensional price-time grid and colors every cell by how much business it hosted. Because the time axis survives, one-off spikes separate cleanly from sustained participation: a liquidity map for traders who build entries, stops, and targets around volume structure. - Indicator in the LuxAlgo Library, by LuxAlgo, published Feb 14, 2026. - Access: free. - Concepts: [Volume Profile](https://www.luxalgo.com/library/concept/volume-profile/) (primary), [High/low-volume Nodes](https://www.luxalgo.com/library/concept/high-low-volume-nodes/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn73tu00a1vhsgotdudt2k - Page: https://www.luxalgo.com/library/indicator/volume-grid-heatmap/ **Volume Grid Heatmap** converts a lookback window into a two-dimensional heat grid: rows are price levels, columns are time intervals, and each cell's color intensity reflects the volume traded there. Where a [volume profile](https://www.luxalgo.com/library/concept/volume-profile/) collapses the window into a single volume-at-price silhouette, the grid preserves the time axis, so a hot level reveals whether it was built by one violent burst or by steady interest across the whole range. Each bar's volume is distributed proportionally over the price rows its range overlaps, the grid is normalized against its busiest cell, and perceptually uniform colormaps keep the intensity scale honest. ## How to Trade the Volume Grid Heatmap? - **Bright cells**: heavy participation at that price and time, zones that often act as support, resistance, or price magnets on a revisit; watch for bounces, absorption, or clean breaks. - **Horizontal clusters**: sustained trade at one price across many intervals builds the kind of [high-volume nodes](https://www.luxalgo.com/library/concept/high-low-volume-nodes/) that define structure rather than noise. - **Isolated or vertical brightness**: a lone bright cell points to a sharp spike from news, liquidations, or aggressive orders; a vertical stack shows activity packed into one time window. Both lean short-term. Typical uses include confirming breakout retests, refining pullback entries and stop placement, and fading moves away from strong liquidity clusters in range-bound conditions. ## Volume Grid Heatmap Settings - **Lookback Bars**: the historical window measured. Shorter suits intraday work, longer exposes structural liquidity for swing trading. - **Rows (Price Resolution)**: vertical precision; more rows sharpen individual levels, fewer merge them into broader zones. - **Columns (Time Resolution)**: horizontal precision; more columns pinpoint when volume arrived, fewer simplify the overview. - **Heatmap Theme / Transparency**: six perceptually uniform palettes (Viridis, Inferno, Magma, Plasma, Cividis, Turbo) plus grid opacity. ## Frequently Asked Questions ### What does the grid show that a profile can't? A profile aggregates volume by price alone; the grid answers at what price and when. If you want the interval-by-interval idea with a point of control per column, the [Volume Profile Matrix](https://www.luxalgo.com/library/indicator/volume-profile-matrix/) takes that route. ### Which markets suit it best? Any liquid market with a reliable volume feed: crypto, equities, indices, futures. Liquidity clustering is most meaningful on heavily traded instruments. ### How do I get the Volume Grid Heatmap? It's free to use via the LuxAlgo Library, no subscription needed. Add it to your chart and it slots into clean layouts and multi-indicator workflows alike. You can also copy the source code from this page and run it anywhere Pine Script® runs. ## Related indicators - [Volume Profile (Maps)](https://www.luxalgo.com/library/indicator/volume-profile-maps/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/volume-profile-maps.md - [Volume Profile Matrix](https://www.luxalgo.com/library/indicator/volume-profile-matrix/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/volume-profile-matrix.md - [Volume Profile Regression Channel](https://www.luxalgo.com/library/indicator/volume-profile-regression-channel/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/volume-profile-regression-channel.md - [Volume Profile with Node Detection](https://www.luxalgo.com/library/indicator/volume-profile-with-node-detection/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/volume-profile-with-node-detection.md - [Anchored Clusters Volume Profile](https://www.luxalgo.com/library/indicator/anchored-clusters-volume-profile/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/anchored-clusters-volume-profile.md - [Clusters Volume Profile](https://www.luxalgo.com/library/indicator/clusters-volume-profile/) (Volume Profile): markdown at https://www.luxalgo.com/library/indicator/clusters-volume-profile.md - [Peak Activity Range](https://www.luxalgo.com/library/indicator/peak-activity-range/) (High/low-volume Nodes): markdown at https://www.luxalgo.com/library/indicator/peak-activity-range.md - [Liquidity Sentiment Profile](https://www.luxalgo.com/library/indicator/liquidity-sentiment-profile/) (High/low-volume Nodes): markdown at https://www.luxalgo.com/library/indicator/liquidity-sentiment-profile.md --- Source: https://www.luxalgo.com/library/indicator/volume-grid-heatmap/ (LuxAlgo Library).
