NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 24/08/2026

Table of Contents
If you’ve been watching the screens, you’ve probably felt the bearish pressure heavily weighing on the major indices, but conducting a thorough Open Interest Volume Analysis reveals the real story beneath the surface. We are witnessing aggressive rollovers and completely diverging sentiments depending on where you look. Here is what is actually happening behind the scenes:
The Broad Weakness: Both NIFTY (Spot at 24,219) and BANKNIFTY (Spot at 57,525) are feeling the heat, with their August futures sliding into a discount. This strongly indicates that the bulls are exhausted and actively unwinding their long positions before expiry.
Bears Pouncing on September: The biggest red flag? Traders aren’t just exiting longs. Our Open Interest Volume Analysis shows a massive surge of fresh short positions being built in the September series—NIFTY futures saw a staggering 51% OI jump alongside a 116% volume spike, while BANKNIFTY saw a 56% OI spike in September. The smart money is positioning for a broader market pullback.
The Midcap Rebellion: It’s not all doom and gloom! MIDCPNIFTY is acting as the lone wolf, flashing a beautiful bullish divergence. While the heavyweights bleed, midcaps are seeing robust short covering in August and an injection of fresh longs for September, backed by a dominant 73% rollover rate.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
So, how exactly do we trade this setup heading into the 25th and 27th expiries? The data is screaming caution for the major indices, but there are still clear, actionable pockets of opportunity if you know where to look. A reliable Open Interest Volume Analysis points to a classic “sell on rise” environment for the heavyweights, while midcaps offer a solid hiding space for the bulls. Here is your actionable game plan:
NIFTY Trade Plan: With the Put-Call Ratio (PCR) plunging to a bearish 0.695 and aggressive call writing capping the upside at 24,300, a breakout looks highly unlikely. Look for low-risk shorting opportunities on any bounce toward 24,300. The Max Pain sits perfectly at 24,200, so expect choppy, range-bound expiry action pinning around this level, with a floor near 24,000.
BANKNIFTY Warning: The bears are fiercely defending the 57,500 zone (highest call addition). Unless we see a convincing close above 57,500, avoid taking fresh longs entirely. Your downside targets sit around the massive 57,000 put base.
SENSEX Reality Check: We are seeing clear long covering and heavy premium decay (down over 83 points). Treat any relief rally toward the 77,500 Max Pain and Call OI peak as a bull trap.
The Midcap Long Play: If you want to buy, stick to MIDCPNIFTY. Our Open Interest Volume Analysis confirms this is where the actual underlying strength lies. Look to accumulate on intraday dips near the 14,900 Max Pain support, keeping your eyes on the 15,200 resistance zone for profit booking. Maintain strict stop-losses, and trade the data, not your emotions!
