Open Interest Volume Analysis

On 12th September 2025, the Indian derivatives market painted a decisive picture through its Open Interest Volume Analysis, signaling a strong influence of short covering across key indices like NIFTY, BANKNIFTY, and FINNIFTY. Nifty futures closed with a premium of 91 points even as open interest dropped by 2.5%, indicating that bearish hands were forced to exit positions.

Meanwhile, the weekly Nifty options showed a rising PCR (OI) at 1.331, hinting at supportive put-writing near 25,100 levels. What’s striking is the parallel movement in Bank Nifty and Finnifty, both showing similar short-covering trends, albeit with a cautious undertone in option activity. This synchronized derivatives move, as reflected in the Open Interest Volume Analysis, suggests a shift in sentiment from defensiveness to selective bullish undertones ahead of the weekly expiry.

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

The derivatives setup for 12th September 2025 reflects a market going through a tactical reset. Nifty’s max pain level at 25,100 aligns perfectly with the highest put additions, suggesting strong support for the short term. Bank Nifty, with both highest call and put additions at 55,000, highlights a possible make-or-break zone as traders prepare for upcoming volatility.

FINNIFTY’s heavy OI unwinding shows profit-taking, while MIDCPNIFTY is standing out with fresh long formations, pointing towards strength in midcaps. SENSEX futures, on the other hand, quietly built fresh long positions, reinforcing the broad-market resilience. Overall, the Open Interest Volume Analysis reveals that while the immediate momentum comes from short covering, the underlying structure is tilting towards a bullish bias—if global cues allow, a breakout could be on the cards before the next expiry.
