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

Nifty 50 Strategy: Our Open Interest Volume Analysis reveals heavy fresh shorting across Nifty futures, backed by an 87% surge in volume and steadily dropping premiums. With the weekly Put-Call Ratio plunging to 0.754, bears are clearly pressing their advantage.

Actionable Feedback: Treat minor bounces as sell-on-rise opportunities as long as the index stays below the 24400 call writing wall. However, do not get complacent—there is a strong possibility of vicious short-covering above the monthly max pain at 24500. If the market crosses that line, early shorts will be trapped, flipping the momentum instantly in favor of the bulls.

Bank Nifty Strategy: We have a clear divergence here compared to the broader market. The Open Interest Volume Analysis points to fresh longs building in the August contract and active short-covering taking place in September.

Actionable Feedback: The data suggests a solid buy-on-dips approach. The aggressive put writing at 57500 offers a great support cushion. If we manage to sustain above the 57900 max pain level, expect a quick dash toward the massive 58000 resistance zone.

Midcap Nifty Strategy: This index is showing silent but resilient strength, with fresh longs rolling over into the September series and a very balanced monthly PCR of 1.005.

Actionable Feedback: The max pain and highest put addition both sit perfectly at 14900, creating a concrete floor for the bulls. Keep trailing your long positions with a strict stop below 14900, keeping an eye on the 15500 call resistance zone for ultimate profit booking.

Sensex Strategy: Sensex is flashing some exhaustion signs with classic long unwinding (Open Interest dropping by 3.78% alongside falling prices and premium decay).

Actionable Feedback: Bulls are clearly taking risk off the table. Stay nimble and avoid aggressive fresh entries until we see a definitive reaction around the critical weekly max pain level of 78000.
