NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 7/10/2025
Table of Contents
On 7th October 2025, the Open Interest Volume Analysis across combined contracts (October, November, December) showed a market caught between cautious optimism and tactical profit-taking. Nifty’s combined futures open interest dipped by 1.2% despite minor spot gains, signaling that the trading session was dominated by short covering—bulls booking profits rather than fresh buyers entering. Open interest contraction in Nifty and Bank Nifty aligned with falling volumes, reinforcing that liquidation, not accumulation, drove most intraday moves.
Interestingly, while both Nifty and Bank Nifty saw net OI reduction, November series recorded fresh long interest in both, hinting that some traders are rolling their bullish bias forward even as near-term contracts unwind. In FINNIFTY, combined futures OI rose 1.7% with prominent long build-up in both October and November contracts, marking financials as a bright spot. Midcap Nifty too reflected mixed positioning, with short covering in near contracts and new longs emerging for November.
On the options front, most indices showed cooling PCR in both weekly and monthly series; highs in call additions at resistance strikes suggest capped upside, while strong put presence near max pain levels reveals hedged optimism. Altogether, today’s Open Interest Volume Analysis paints a picture of a market preparing for expiry volatility with a balance of risk-off moves and select bullish carry-forward.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives setup for 7th October 2025 offers a nuanced view—traders remain defensive on expiry-week contracts, as Nifty and Bank Nifty see heavy short covering and flat-to-lower open interest, but fresh longs in November series suggest underlying bullishness is quietly building for the weeks ahead. Finnifty’s lasting combined OI growth and consistent long buildup point to continued strength in financials, while midcaps follow a similar recovery path as shorts exit and fresh longs arrive.
Still, options data highlights that call writers are placing barriers at higher levels, and muted PCR ratios across most indices mean any upside is likely to be gradual and contested. The overall Open Interest Volume Analysis signals expiry-induced sideways moves in the near term, with real directional strength poised to emerge only once the bulk of profit-taking has run its course and fresh long positions start to dominate across all time frames.
