NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 15/10/2025
Table of Contents
On 15th October 2025, the Open Interest Volume Analysis delivered a clear message: market bulls are getting back in the driver’s seat. Nifty’s combined futures open interest jumped 3.1% as prices bounced smartly, showing that traders are building fresh long positions in both October and November contracts. That bullish bias was even more apparent in November, where OI leapt 31.5%—strong proof that traders are deploying new capital into November’s trend, not just rolling over old longs.
This renewed conviction showed up across Bank Nifty as well, where combined OI rose 2.5% entirely on the back of fresh long accumulation. Meanwhile, in the options arena, PCRs in both weekly and monthly Nifty expiry climbed past 1.0, showing a healthy pickup in put writing and solidifying the support base around 25,300. The flip side? Finnifty and Midcap Nifty, despite rising prices, saw combined OI contract further—demonstrating persistent short covering as traders raced to exit bearish bets, adding to the upward momentum.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives data for 15th October 2025 makes the directional bias clear: today’s market action was driven by a mix of aggressive new bullish positions and a full-throttle unwind of shorts. Both Nifty and Bank Nifty saw strong fresh long additions, while call OI lagged put OI, pointing to improving support and traders’ belief in continued upside. At the same time, heavy short covering across financials and midcaps added fuel to the momentum. Actionable feedback:
If you’re long, ride the wave—but track OI for Nifty around 25,548 (November) and Bank Nifty at 57,274 for evidence of further aggressive build-up or signs of long unwinding. Profit-takers may want to consider trailing stops or locking in gains near recent highs, while cautious traders should wait for dips; let the market show new OI spikes before re-entering. In short, today’s Open Interest Volume Analysis tells traders to trust the rally for now, but watch for signs of exhaustion or resistance near overhead call OI strikes.
