How to Use the Heatmap Generator

This tool allows you to create a visual heatmap from your own stock market data.

  1. Enter a Title (Optional): Give your heatmap a descriptive title on the "Create Heatmap" tab.
  2. Prepare Your Data: You need to provide data for each stock in the following format, with each stock on a new line:
    STOCK_SYMBOL,PERCENT_CHANGE,WEIGHTING_FACTOR
    • STOCK_SYMBOL: A short identifier for the stock (e.g., AAPL, RELIANCE.NS, MSFT). Avoid spaces or special characters if possible for best display.
    • PERCENT_CHANGE: The percentage change in the stock's price. Use positive numbers for gains (e.g., 1.5 for +1.5%) and negative numbers for losses (e.g., -0.8 for -0.8%). Do not include the '%' symbol.
    • WEIGHTING_FACTOR: A positive numerical value that determines the relative size of the tile for this stock. This could be based on market capitalization (e.g., in billions USD or crores INR - ensure consistency for all entries), trading volume, or any other metric you choose to represent size. Larger numbers will result in relatively larger tiles.
  3. Paste Your Data: Copy your prepared data and paste it into the "Stock Data" textarea on the "Create Heatmap" tab.

    Example Data:

    AAPL,1.75,2800
MSFT,-0.50,2500
GOOG,0.20,1800
AMZN,2.10,1500
TSLA,-1.90,700
NVDA,3.5,1200
INFY.NS,0.8,70  (Example for Indian stock, weight in appropriate relative unit)
HDFC üçBANK.NS,-0.3,90 (Example for Indian stock)

    (Note: The example weights are illustrative. For actual market cap based sizing, you'd use real market cap figures, e.g., 2800 for $2.8T, or 70 for ₹70 Lakh Crore if that's your consistent unit).

  4. Configure Colors (Optional): Adjust the percentage thresholds that define strong gains, moderate gains, neutral, moderate losses, and strong losses to customize the color scheme of your heatmap.
  5. Generate: Click the "Generate Heatmap" button. Your heatmap will appear below.
  6. Download (Optional): Once generated, you can click "Download Heatmap as PDF".

Understanding the Heatmap

  • Tile Color: Indicates the stock's performance (% change). Typically, green shades represent gains, and red shades represent losses. The intensity of the color corresponds to the magnitude of the change based on your configured thresholds.
  • Tile Size: Represents the relative 'weight' or 'importance' of the stock based on the WEIGHTING_FACTOR you provided. Larger tiles mean a higher weighting factor.
  • Tile Label: Shows the stock symbol and its % change.

This tool is for visualizing data you provide. It does not fetch live market data.
