Not all indicators are suitable for every market instrument—and the Open Interest (OI) indicator is a perfect example. On FYERS platforms, OI is designed for derivatives only. It reflects the number of outstanding (open) contracts and is useful for gauging sentiment, the strength behind price moves, and potential reversals in F&O.
The OI indicator is available and meaningful on these derivative instruments:
• Stock Futures
• Index Futures
• Stock Options
• Index Options
The OI indicator is not available or meaningful on:
• Cash market stocks (EQ segment)
• Main indices in spot (e.g., NIFTY 50, BANK NIFTY)
• Non-derivative instruments (e.g., bonds, and ETFs without F&O)
Note
Open interest is published only for markets where derivative contracts trade. If an instrument has no F&O, OI will not be shown on charts or related widgets.
| Scenario | Solution |
|---|---|
| You apply OI to a stock chart with no F&O segment | OI won’t display. Use the indicator only on instruments that have listed derivatives. |
| You try to apply OI to a NIFTY spot index chart | Not supported on spot. Apply OI to the corresponding NIFTY Futures contract instead. |
| OI shows as zero or flat | This can occur during non-trading hours or in illiquid contracts. Check market hours and contract liquidity. |
