Open Interest (OI) Analysis

Total Call OI stands at 42.14 lakh contracts against Total Put OI of 67.57 lakh contracts, with Put OI running well ahead of Call OI for this expiry, a sharp swing from the Call-heavy skew of the previous SENSEX 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 Put OI on the entire chain sits at the 74,000 strike, below current spot, making it the primary support zone for the week. A secondary Put concentration appears further out at 73,500.

•The heaviest Call OI is concentrated at the 75,000 strike, with 74,500 close behind, together forming the primary resistance band above current spot. A sizeable Call cluster also sits at 74,000, alongside the heavy Put OI there, and a further one at 74,800.

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 heaviest at the 74,000 strike, reinforcing it as the key support level for the week, with a secondary addition at 73,500. Fresh Call writing is heaviest at the 74,500 strike, followed by 74,800 and 74,000, with a further addition at 75,000.

This lines up with the cumulative OI picture: writers are reinforcing 74,000 as the floor for this expiry, while Call writers are building a ceiling in the 74,500–75,000 band, with Put-side positioning still the heavier of the two.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 1.60, meaning Put OI outweighs Call OI by a wide margin.

A PCR well above 1 generally reflects heavier Put writing relative to Call writing. Since option writers typically sell options they expect to expire worthless, a PCR in this range is conventionally read as a bullish-leaning signal, with Put sellers positioning for SENSEX to hold above their strikes rather than expecting a sharp decline. It also marks a clear reversal from the 0.86 reading on the previous SENSEX 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.

1.Structural range: 73,240.11 – 75,391.11, with a tighter 73,904.77 – 74,726.45 zone as the more probable trading band.

5.PCR: 1.60, bullish-leaning bias, a clear shift from last SENSEX expiry.

Together, this points to 74,000 as the level to watch on the downside this week, with the 74,500–75,000 band as the zone to watch on the upside if the current range gives way.
