NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 16/10/2025
Table of Contents
On 16th October 2025, the Open Interest Volume Analysis revealed a decisive return of bullish conviction across Indian markets, with most major indices showing combined futures open interest and prices rising in tandem—a hallmark of fresh long build-up. Nifty’s combined open interest was up 0.7% even as the spot closed 1% higher, with the November contract seeing especially aggressive fresh longs (+13.6%). October contracts saw light short covering, suggesting traders are paring down expiring positions and focusing new risk toward November’s trend.
Bank Nifty sustained this optimism: combined open interest climbed 1.8%, with bullish flows again centered in November contracts. The uptrend’s breadth was clearest in Finnifty and Midcap Nifty, where both indices saw robust OI and price gains across contracts—Midcap Nifty in particular had a combined OI jump of 3.6%, fueled by savvy traders chasing continued momentum in the broader market space. In the options arena, soaring put-call ratios across weekly and monthly expiries for Nifty, Bank Nifty, and Midcaps confirm heavy put writing at emerging support levels—evidence that market participants are backing the bullish breakout with real capital.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
For 16th October 2025, today’s Open Interest Volume Analysis validates the ongoing rally with conclusive evidence of new money entering long-side bets across indices. Aggressive OI additions in Nifty, Bank Nifty, and especially Midcap Nifty and Finnifty reflect traders’ confidence that this breakout can sustain—at least for the near term. The simultaneous jump in put writing and rise in max pain levels in options reaffirms that support is shifting higher, but narrowing premiums and brisk rollovers warn traders not to get complacent.
Actionable feedback: Those already long should monitor OI trends in November contracts (Nifty above 25,786, Bank Nifty over 57,784, and Midcap Nifty above 13,370) for signs of strength continuation or abrupt unwinding. If OI drops or new shorts appear near resistance (especially at big round numbers or after a rapid surge), consider partial profit-booking or deploying trailing stops. For late entrants, wait for small dips toward max pain or strong put OI levels before adding risk.
In summary, today’s Open Interest Volume Analysis compels traders to ride the momentum, but stay nimble—as overbought readings and declining premiums can quickly shift sentiment, especially into expiry.
