NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 3/10/2025
Table of Contents
On 3rd October 2025, the Open Interest Volume Analysis for combined futures contracts (across October, November, and December) signaled renewed market confidence after expiry. Nifty saw a healthy 4.3% rise in combined open interest, driven entirely by fresh long build-up despite slipping volumes—a sign that participants are positioning for higher levels rather than unwinding.
This bullish sentiment echoed throughout Bank Nifty as well, with combined OI up by 1.9% and solid long accumulation in October even as November contracts saw short covering. Finnifty took the spotlight with a robust 20.5% spike in combined OI, fueled by aggressive long additions in both the near and far series, reflecting surging optimism in financials. Even Midcap Nifty maintained a subtle uptrend with ongoing fresh long build-up, rounding out a day characterized by selective accumulation and new risk-taking, rather than caution.
In the options space, a small cooling in PCR across Nifty, Bank Nifty, and Finnifty suggests that while bulls hold the advantage, call writers are staying alert at higher strikes. Overall, today’s Open Interest Volume Analysis spotlights a zone where the long side is regaining dominance, but not without competition.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The F&O data for 3rd October 2025 paints a cautiously optimistic view, with rising combined futures OI and fresh longs showing traders are willing to back further gains as the new series unfolds. Nifty’s strong long additions amid contained volumes suggest conviction is present, even if momentum isn’t runaway. Bank Nifty’s fresh long interest and Finnifty’s outstanding OI increase highlight that financials remain the backbone of the market’s bullish bias.
Midcap Nifty, though less explosive, supports the case that risk appetite hasn’t vanished, with selective adding continuing at every dip. Still, slightly lower PCRs in options for indices like Nifty and Sensex remind us that sharp resistance is likely near overhead calls, and that traders’ optimism is being met with caution at every bounce. In summary, this Open Interest Volume Analysis tells us that the post-expiry market is loaded with bullish intent, but remains balanced by vigilant risk management—and the next leg up will need a decisive breakout above crowded resistance levels.
