NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 10/10/2025
Table of Contents
On 10th October 2025, the combined futures and options landscape revealed a market in transition, as Open Interest Volume Analysis pointed to broad short covering in key indices just as some participants began to rebuild bullish positions further out. Nifty’s combined futures open interest slipped by 0.5%, showing a session dominated by short covering rather than aggressive buying, even as spot prices climbed.
However, November Nifty contracts stood out with an impressive 8.6% OI jump—signaling investors are planting fresh long bets for the weeks ahead, anticipating stronger trends post expiry. Bank Nifty confirmed this bullish undertone, with combined OI up 3.9% from strong accumulation across contracts; notably, November saw sharp fresh long additions that reinforce sectoral optimism. Finnifty, after some profit-taking in near contracts, saw powerful long build-up in November series.
Midcap Nifty and Sensex futures also mirrored the overall short covering, underscoring a cautious, profit-booking mood as traders reset positions at current highs. In options, PCR ratios soared across indices, indicating that put writers are supporting the market at higher bases while call additions maintain resistance close overhead. Today’s Open Interest Volume Analysis captures a market preparing for a new direction by switching gears, with fresh long bets quietly gathering beneath the surface.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives scene for 10th October 2025 reflects traders using short covering to book profits in the October series, while select participants rebuild bullish exposure in November contracts—especially in Nifty, Bank Nifty, and Finnifty. The jump in combined OI for Bank Nifty and the persistent fresh longs in financial indices hint at sector rotation and renewed buying, even as midcaps and Sensex remain focused on trimming risk.
Rising PCR values across weekly and monthly options confirm that market support is strengthening at lower levels, but persistent call additions near resistance mean any breakout will be contested. The overall Open Interest Volume Analysis shows that the broad market is readying for a strategic move post expiry, with new bullish positions slowly forming, while profit-taking and resistance could still lead to choppiness in the days ahead.
