Open Interest (OI) Analysis

Total Call OI stands at 1,035.75 lakh contracts against Total Put OI of 679.57 lakh contracts, with Call OI running well ahead of Put OI 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 on the chain sits at the 23,400 strike, with a close second at 23,500. Together these mark the primary resistance band for the week, with a further Call build-up visible at 23,600.

•The heaviest Put OI is concentrated at the 23,000 strike, just below current spot, making it the immediate support zone. A secondary Put concentration appears at 23,200, above spot.

•The strikes closest to spot (23,100–23,150) show comparatively light OI on both sides relative to the heavier clusters on either flank.

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 23,400 strike, reinforcing it as the key resistance level for the week, with further notable additions at 23,200, 23,300 and 23,500. Fresh Put additions are smaller in scale overall, concentrated mainly at 23,200 and 23,000.

The pattern shows Call writers building aggressively across the 23,200–23,500 band above spot, while Put-side additions remain comparatively modest. This is consistent with the cumulative OI picture: writers are putting more conviction behind capping the upside than defending the downside.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 0.6561, meaning Call OI outweighs Put OI by a meaningful margin.

A PCR well below 1 generally reflects heavier Call writing relative to Put writing. Since option writers typically sell options they expect to expire worthless, a PCR in this range is conventionally read as a mildly bearish-to-neutral signal, with Call sellers positioning for NIFTY to stay capped below their strikes rather than expecting a sharp rally.

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.

1.VIX-implied range: 22,687.03 – 23,550.17, with a tighter 22,902.82 – 23,334.38 zone as the more probable trading band.
