Reading the heatmap
Each tile is one stock listed on NSE; switch between all stocks, F&O stocks, the main board or the SME platform. Bigger tiles traded more value (price × volume) in the last session, so the largest names show the money flow. Green tiles are up and red tiles are down; the deeper the colour, the bigger the move. Switch the colour to 1 week, 1 month or 3 months to see trends instead of today's move.
