Is the Open Interest indicator applicable to all types of charts on FYERS?
Not all indicators are suitable for every market instrument—and the Open Interest (OI) indicator is a perfect example. On FYERS platforms, this indicator is tailored specifically for derivative instruments like Futures and Options.
Where the OI indicator works?
The OI indicator displays the number of outstanding (open) contracts in the derivatives market. It's an important metric in Futures and Options trading, helping traders understand market sentiment, strength of price moves, and potential reversals.
- Stock Futures
- Index Futures
- Stock Options
- Index Options
Where it doesn’t apply?
The OI indicator is not available or meaningful on:
- Cash market stocks (EQ segment)
- Main indices (e.g., NIFTY 50, BANK NIFTY in spot)
- Non-derivative instruments (e.g., bonds, ETFs without F&O)
This is because open interest data is only relevant where derivative contracts are traded.
What if...
| Scenario | Resolution |
|---|
| You apply OI to a stock chart with no F&O segment | The OI indicator won’t display. Use only on instruments with derivatives. |
| You try to apply OI to NIFTY index spot chart | Not supported. Instead, apply it to NIFTY Futures. |
| OI shows as zero or flat | This can happen during non-trading hours or for illiquid contracts. Confirm market hours and instrument activity. |
If you’re analysing Options chains or planning futures strategies, always pair the OI indicator with volume and price to validate trends. A rising price with rising OI often signals a strong trend.
