Open Interest (OI) Analysis

Total Call OI stands at 1,458.56 lakh contracts against Total Put OI of 1,284.20 lakh contracts, with Call OI back ahead of Put OI for this expiry after last week's Put-heavy skew. 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 23,000 strike, just above current spot, making it the primary resistance zone for the week. Secondary Call concentrations appear at 23,200 and 23,300, with further clusters at 23,100 and right at spot near 22,900.

•The heaviest Put OI is concentrated at the 22,500 strike, well below current spot, marking the primary support zone. Secondary Put concentrations appear at 22,700, 22,800 and 22,600, and a sizeable Put cluster also sits at 23,000 alongside the heavy Call OI there.

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 23,000 strike, the largest addition on the board, with further strong additions right at spot near 22,900 and across 23,100, 23,200 and 23,300. Fresh Put additions are much smaller in scale, with the largest at 22,800 and 22,900, and a smaller addition at 22,500.

This lines up with the cumulative OI picture: Call writers are reinforcing 23,000 as the ceiling for this expiry and building a stack of resistance above it, while Put-side additions this week are modest.

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. This is a reversal from the Put-heavy 1.38 reading on the previous NIFTY expiry.

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

Putting the data points together for the October 27 expiry:

1.Structural range: 22,546.55 – 23,231.35, with a tighter 22,758.15 – 23,019.75 zone as the more probable trading band.

2.OI-based resistance: heaviest Call OI at 23,000, with secondary zones at 23,200 and 23,300.

3.OI-based support: heaviest Put OI at 22,500, with secondary zones at 22,700, 22,800 and 22,600.

4.Fresh Call writing (Change in OI) heavily reinforcing 23,000, well ahead of fresh Put writing.

5.PCR: 0.88, mildly cautious-to-neutral bias, a reversal from last NIFTY expiry.

Together, this points to 23,000 as the level to watch on the upside this week, with 22,500 as the stronger, more distant support if the current range gives way.
