How should I interpret changes in Open Interest alongside price movements on FYERS charts?
Open Interest (OI) represents the total number of outstanding futures and options contracts in the market.
When you track OI along with price movements on FYERS charts, you can understand position buildup, unwinding, and possible shifts in market sentiment.
OI is available only for derivative instruments such as index and stock futures and options.
Interpreting open interest with price movements
| Scenario | Interpretation | Market sentiment |
|---|
| Increasing OI + Increasing price | Long buildup | Bullish |
| Increasing OI + Decreasing price | Short buildup | Bearish |
| Decreasing OI + Increasing price | Short covering | Bullish reversal |
| Decreasing OI + Decreasing price | Long unwinding | Bearish reversal |

What if...
| Condition | Solution |
|---|
| OI remains flat while price moves | Traders may not be adding new positions and trend conviction could be weak. |
| Both price and OI fall sharply after a news event | Existing positions may be getting unwound and the move could reflect panic or early signs of a reversal. |
| OI surges but price stays in a range | Positions may be building up and a breakout or breakdown could follow. |
For stronger confirmation, combine OI with volume and trend indicators instead of relying on OI alone.
