## Frequently asked questions

### How do I read the F&O heatmap?

Each tile represents a stock in the NSE F&O universe. Tile size reflects trading volume and tile colour reflects the combined price-plus-OI signal: green for long buildup (bullish), red for short buildup (bearish), blue for short covering, and yellow/orange for long unwinding. A glance tells you where the biggest and most meaningful action is happening.

### What makes the heatmap better than a table?

The visual encoding makes patterns jump out. Clusters of green tiles in the same sector reveal sector rotation in progress. A few large red tiles signal stock-specific selling. Broad red across many tiles signals market-wide risk-off. Tables force you to read and interpret; the heatmap shows patterns at a glance.

### Can I filter by sector?

Yes. You can filter the heatmap view by Nifty 50, BankNifty, FinNifty, Midcap, or sectoral indices. This lets you focus on the slice of the market that matters for your strategy — for example, only IT stocks, only banks, or only the Nifty 50 constituents.

### What does tile size tell me?

Tile size is proportional to trading volume (or OI, depending on mode). Large tiles are the most actively traded names — their moves affect the index more and attract more institutional interest. Small tiles are lightly traded stocks whose moves are less reliable signals.

### How often does the heatmap update?

Every few seconds during NSE market hours (9:15 AM to 3:30 PM IST). You can watch the heatmap evolve through the session — morning positioning may flip in the afternoon, revealing rotation as it happens.

### Is the heatmap good for end-of-day review?

Yes. End-of-session heatmaps provide a compact summary of the full day's activity, making post-market review much faster than scrolling through tables. Screenshot the heatmap at close and compare to the next day's morning heatmap to see what changed overnight.

## How to use the F&O Heatmap

1. **Pick a filter** — Start with the Nifty 50 or BankNifty filter to focus on index constituents, or pick a sector to see sector-specific action.
2. **Scan the largest tiles** — Biggest tiles are the most-traded names. Their colour tells you the dominant phase — green for long buildup, red for short buildup.
3. **Look for colour clusters** — Same-colour clusters in the same sector row reveal sector rotation. Scattered colours indicate stock-specific moves rather than broad trends.
4. **Check colour transitions** — If a tile flips from green to blue over the session, long buildup turned into short covering — the trend is losing steam.
5. **Click tiles for detail** — Click into any tile to see the underlying stock's detailed price and OI charts for that session.
