Sector Heatmap Improvements: Missing Index Coverage & Timeframe UI Optimization

I have been a active user of Fyers and really appreciate the platform. I wanted to share a few structured observations specifically around the Sector Heatmap feature that, if improved, could significantly enhance usability & decision-making speed for traders.

1. Sector Coverage & Consistency
Currently, both sectoral & thematic indices are visible, but there seems to be inconsistency in coverage. Example, Energy is categorized as a thematic index on the National Stock Exchange of India (NSE), is missing, while Infra is present.

This creates a gap in sectoral representation and may lead to incomplete market interpretation.

A more robust approach would be: Ensuring all major sectoral and thematic indices are included and structuring them based on market capitalization or relevance.

This would make the heatmap more comprehensive and aligned with how traders actually analyze sector rotation.

2. Timeframe Selection UI (Change % Bar)

The current layout for '1 min chg %', '5 min chg %' feels slightly inefficient from a UX perspective, especially for users switching between multiple timeframes.
A more scalable and intuitive design could be:

Change % | 1m | 5m | 15m | 30m | 60m | 1D | 1W | 1M

This reduces horizontal scrolling and aligns better with different trading styles (scalpers, intraday & swing traders) hence improving interaction speed.

These suggestions are based on consistent usage and discussions with other active users, many of whom share similar observations.

Would be great to see these enhancements considered, as they can further strengthen an already solid platform.
