Open Interest (OI) Analysis

Total Call OI stands at 778.44 lakh contracts against Total Put OI of 877.09 lakh contracts, with Put OI running ahead of Call OI for this expiry — a change from the Call-heavy skew seen in recent weeks. 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 Put OI on the entire chain sits at the 22,700 strike, just below current spot, making it the primary support zone for the week. Secondary Put concentrations appear at 22,500 and 22,600.

•The heaviest Call OI is concentrated at the 23,000 strike, marking the primary resistance zone. Secondary Call concentrations appear at 22,800 (near spot), 23,100 and 23,200.

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 Put writing is clearly heaviest at the 22,700 strike, reinforcing it as the key support level for the week, with further notable additions at 22,500 and 22,600. Fresh Call writing is heaviest at the 23,100 strike, with secondary additions near spot at 22,700–22,800 and further out at 23,200.

This lines up with the cumulative OI picture: writers are actively reinforcing 22,700 as the floor for this expiry, while Call-side conviction is building slightly higher than the heaviest cumulative Call strike, at 23,100.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 1.12, meaning Put OI now outweighs Call OI.

A PCR above 1 generally reflects heavier Put writing relative to Call writing. Since option writers typically sell options they expect to expire worthless, a PCR above 1 is conventionally read as a mildly bullish-to-neutral signal, with Put sellers positioning for NIFTY to hold above their strikes rather than expecting a sharp decline. This marks a shift from the Call-heavy, mildly bearish-to-neutral PCR readings of recent weeks.

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.
