Open Interest (OI) Analysis

Total Call OI stands at 53.46 lakh contracts against Total Put OI of 47.27 lakh contracts, with Call OI running slightly 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 on the entire chain sits at the 74,000 strike, well above current spot, making it the primary resistance zone for the week. A secondary Call concentration appears at 74,500.

•The heaviest Put OI is concentrated at the 73,000 strike, below current spot, marking the primary support zone. A secondary Put cluster sits closer to spot at 73,600.

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 clearly heaviest at the 74,000 strike, reinforcing it as the key resistance level for the week, with a secondary build-up at 74,500. Fresh Put additions are concentrated close to spot at 73,600, with a smaller secondary addition at 74,000.

This lines up with the cumulative OI picture: writers are actively reinforcing 74,000 as resistance, while Put-side conviction this week is building closer to spot rather than at the more distant 73,000 support.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 0.88, 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.

What This Means for the Week

1.Structural range: 72,494.54 – 74,666.54, with a tighter 73,165.69 – 73,995.39 zone as the more probable trading band.
