Open Interest (OI) Analysis

Total Call OI stands at 53.78 lakh contracts against Total Put OI of 46.31 lakh contracts, with Call OI running ahead for this expiry. If you're not familiar with how Open Interest is built up and interpreted, What Is Open Interest? A Beginner's Guide to OI in Options Trading covers the basics.

The OI distribution across strikes shows clear concentration zones on both sides:

•The heaviest Call OI sits at the 72,500 strike, with 72,000 almost level with it, together forming the primary resistance band above current spot. A further Call concentration appears just below spot at 71,500.

•The heaviest Put OI on the chain is concentrated at the 71,500 strike, just below current spot, marking the primary support zone. Secondary Put clusters appear at 72,500, 71,000 and 72,000.

•With heavy Call and Put OI both at 71,500, that strike stands out as the near-spot pivot zone for the week.

Change in OI Analysis

Looking at fresh Open Interest additions for the day rather than the cumulative total gives a read on where positioning is actively building right now.

Fresh Call writing is heaviest at the 72,000 strike, reinforcing it as the key resistance level for the week, with further notable additions at 71,500 and 72,500. Fresh Put additions are concentrated at 71,500, with much smaller secondary additions at 71,000 and 72,500.

This lines up with the cumulative OI picture: writers are reinforcing 72,000 on the upside, while 71,500 is the zone where both sides are most actively positioning right now.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 0.86, meaning Call OI modestly outweighs Put OI.

A PCR just below 1 generally reflects a slight tilt toward Call writing over Put writing, without being as skewed as a reading well below 0.7. Since option writers typically sell options they expect to expire worthless, a PCR in this range is conventionally read as a mildly cautious-to-neutral signal, with Call sellers showing a modest lean toward capping the upside.

That said, PCR is one data point among several, and a single week's reading should be considered alongside price action and the broader OI structure rather than in isolation.
