## Frequently asked questions

### What's different about F&O Market Movers?

F&O Market Movers focuses specifically on the NSE F&O universe — index futures and all F&O stocks — with deeper OI-driven classifications than the general Market Movers page. It's tuned for derivatives traders who care about positioning flow rather than just price.

### How do I spot sector rotation?

Use the sector heatmap view. When one sector row lights up with multiple names in long buildup while another sector shows widespread short buildup or unwinding, rotation is in progress. This often precedes sector-level index moves by a day or two.

### What is the bullish/bearish ratio?

A market-wide read derived from the relative count of stocks in bullish phases (long buildup + short covering) versus bearish phases (short buildup + long unwinding). Above 1.5 signals broad bullish positioning; below 0.67 signals broad bearish positioning. A gauge of overall market regime.

### Can I watch this in real time?

Yes. All tables and heatmaps update every few seconds during NSE market hours. You can leave the page open as a live dashboard — the top lists and sector breakdowns evolve as new flow arrives, letting you catch regime shifts as they develop.

### How is OI spurt defined here?

An OI spurt is a change in open interest that's large relative to the stock's recent OI — typically 10% or more of the prior day's OI in a single session, or 25% or more compared to the 10-day average. Filters are tuneable so you can focus on bigger or smaller spurts depending on your threshold.

### Do the signals work on low-volume F&O stocks?

Signals are more reliable on liquid names (Reliance, HDFC Bank, ICICI Bank, SBIN, etc.) because their OI moves reflect genuine institutional flow. Thinly-traded F&O stocks produce noisier signals. The volume filter lets you exclude names below a chosen activity threshold.

## How to use F&O Market Movers

1. **Check the bullish/bearish ratio** — Start with the market-wide sentiment gauge. Above 1.5 → broad bullish regime, favour long setups. Below 0.67 → broad bearish regime, favour short setups.
2. **Identify the top-performing sector** — Look at the sector heatmap to see which sector has the most long-buildup names. Trade with sector flow, not against it.
3. **Screen OI spurt list for ideas** — OI spurt stocks are where institutional positioning changed dramatically. Cross-reference with price change to classify direction.
4. **Apply a volume filter** — Exclude names below your minimum volume threshold to focus on liquid F&O instruments where signals are reliable.
5. **Confirm with intraday chart** — Click any name to inspect its price vs OI intraday pattern before committing capital.
