Quick Answer
The Market Heatmap is a free real-time treemap visualization that displays 500+ S&P 500 stocks organized by sector and sized by market capitalization. Each stock block is color-coded from deep green (strong gains) to deep red (significant losses), letting investors instantly identify sector trends, momentum shifts, and portfolio concentration risk using live data from TradingView.
Real-time price data streams from TradingView for all S&P 500 constituents, US ETFs, and major cryptocurrencies with sub-minute refresh rates.
Each stock's percentage change is computed against the previous close. Gains and losses are normalized to produce accurate color intensity mapping.
Stocks are grouped into 11 GICS sectors. Block size is proportional to market capitalization — larger companies like AAPL and MSFT occupy more visual space.
Deep green indicates strong gains (>3%), light green modest gains, light red modest losses, and deep red significant losses (>3%). Color intensity reflects conviction level.
We aggregate and cross-verify data from multiple institutional-grade financial APIs. No single point of failure.
All data verified and cross-referenced. Not financial advice.
The heatmap uses a green-to-red color scale to represent stock performance. Deep green indicates strong gains (typically above +3%), light green shows modest gains, light red means modest losses, and deep red signals significant losses (below -3%). The intensity of the color reflects the magnitude of the price change, letting you quickly gauge market sentiment at a glance.
The heatmap updates in real time during market hours using live data from TradingView. Price changes, color coding, and block sizes refresh continuously so you always see the current state of the market. Outside of market hours, the heatmap displays the most recent closing data.
The heatmap covers all 11 GICS (Global Industry Classification Standard) sectors: Technology, Healthcare, Financials, Consumer Discretionary, Consumer Staples, Energy, Industrials, Materials, Real Estate, Utilities, and Communication Services. Stocks are grouped by sector so you can instantly see which sectors are leading or lagging.
Block size represents market capitalization. Larger companies like Apple (AAPL) and Microsoft (MSFT) have bigger blocks because they represent a larger share of the index. This weighting mirrors how the S&P 500 index itself is constructed, giving you an accurate visual representation of market impact.
