How the Heatmap Works
The sector heatmap displays each CSE sector as a coloured block. Green shading indicates positive performance for the session. Red shading indicates negative performance. The intensity of the colour reflects the magnitude of the move — bright green means a strong gain, bright red means a sharp decline. Neutral or flat sectors appear in muted tones near grey.
What You Can Identify Quickly
Using the Heatmap for Stock Selection
When a sector shows consistent green performance over several sessions, it is worth exploring the stocks within that sector for individual opportunities. Open the Discover page, filter by the outperforming sector, and sort by percentage gain to see which specific stocks are driving the sector move.
Check the heatmap before setting new alert rules. If the banking sector is broadly under pressure, setting a price_above breakout alert on a bank stock in a weak sector requires more conviction than a similar alert on a stock in a leading sector.
Heatmap vs Sector Snapshots
The heatmap gives you a fast visual read on sector performance. For more precise sector data including individual stock change values within a sector, use the sector snapshots view on the Market Overview page which shows each sector's aggregate index value, change, and volume in tabular format.
