NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 13/10/2025
Table of Contents
On 13th October 2025, the Open Interest Volume Analysis revealed a nuanced shift in index sentiment: traders balanced fresh shorts in Nifty and Sensex with selective long buildup across midcaps and financials. Nifty’s combined futures open interest edged up by 0.4%—a signal that bears are tentatively building fresh shorts, even as October contracts saw modest long covering while November contracts attracted new short interest.
The bright spot in the session came from Bank Nifty and Finnifty, where fresh long positions dominated combined futures activity despite mixed price action, hinting at sector rotation and optimism in banking and financials. Midcap Nifty mirrored this positivity with steady increases in both price and OI, indicating traders are accumulating for the next leg.
In the options space, the PCR cooled in Nifty, Bank Nifty, and Sensex, while Finnifty and midcaps saw more robust put writing—suggesting confidence but also healthy hedging at higher strikes. Altogether, today’s Open Interest Volume Analysis reflects a market where participants remain tactically cautious in large indices but are actively positioning for upturns in select sectors.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives structure for 13th October 2025 paints an intricate picture: Nifty and Sensex see emerging fresh shorts, confirming some nervousness near recent highs, but the underlying bid in Bank Nifty, Finnifty, and midcap contracts hints at selective bullish conviction. Mixed moves in option chains, with a drop in PCR for heavyweights but stable or rising ratios for midcaps and financial indices, suggest traders are hedging risk but not abandoning longs.
The overall Open Interest Volume Analysis indicates that while headline indices may struggle for immediate direction, underlying sector strength—especially in banking and midcaps—could drive the next move once expiry noise subsides. For investors, keeping an eye on changing OI patterns helps identify where real momentum is building beneath headline volatility.
