Open Interest Volume Analysis

On 29th September 2025, the combined futures and options setup showed that traders are tactically repositioning ahead of expiry. Nifty’s combined futures OI rose 3.9% with volumes up 8.8%, clearly indicating fresh short build-up, even as September contracts saw heavy long covering and October added new shorts. The rollover jumped sharply to 71% from 52%, showing that positions are shifting aggressively into the new series, but under a bearish tilt. Bank Nifty presented a different flavor—combined OI fell 6% with strong rollover (67% vs 48%), reflecting short covering in the near contract and simultaneously fresh longs being built in October.

Finnifty’s combined OI was marginally up by 0.9%, but the real signal was rollover strength, with fresh longs in October signifying sectoral resilience in financials. Midcap Nifty too echoed this pattern, with combined OI softening as September saw unwinding, but October carried forward meaningful fresh long interest. Sensex futures, however, stayed muted with marginal OI drop, showing short covering in the index. The day’s Open Interest Volume Analysis clearly highlights expiry-driven reshuffling where shorts dominate Nifty, but selective long build-up in Bank Nifty, Finnifty, and Midcap Nifty gives the market pockets of support.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us

The derivatives picture for 29th September 2025 sends a mixed but insightful message. On one side, Nifty’s rollover-led fresh short positions and falling PCR (OI) at 0.613 highlight a cautious tone, with resistance clustering around the 24,700–25,000 band. On the other, Bank Nifty’s combined setup indicates that traders are leaning toward dip-buying, as fresh longs sneak into the October series supported by max pain at 54,700.

Finnifty’s futures rollover into longs and slightly improved PCR confirm selective strength in financial-led segments, while Midcap Nifty’s short-term unwinding but rollover-backed long build-up hints at renewed positioning in the broader market beyond expiry. Sensex continues as the balancing act with mild covering, but PCR below 0.70 shows overhead weight remains. Altogether, today’s Open Interest Volume Analysis suggests expiry will likely stay choppy with Nifty under selling pressure, but Bank Nifty and midcaps could surprise with resilience in the new series, keeping the longer-term direction contest alive.
