NIFTY 50 is trading at 23,329.00 as markets head into the September 29, 2026 weekly expiry. This week's outlook combines structural price levels with Open Interest positioning, fresh Change in OI activity, and the Put-Call Ratio to build a fuller picture of how the market is currently positioned.

Weekly Price Snapshot

NIFTY 50 Level: 23,329.00
India VIX: 11.00
Expiry: Tuesday, September 29, 2026

Structural Price Levels

Mapping out the key price levels for NIFTY 50 through the September 29 expiry:

| Level | Price | Type |

|---|---|---|

| Maximum Upside | 23,591.90 | Outer Resistance |

| Upper Level | 23,429.43 | Resistance |

India VIX at 11.00 sits well within the calm volatility band (below 15), pointing to a comparatively narrow expected trading range this week. These levels are a structural reference for monitoring support and resistance through the week, not trade entry points.

India VIX itself is essentially the market's implied volatility reading for the index as a whole. If you're new to how implied volatility shapes option pricing and expected price ranges, see What Is Implied Volatility? A Beginner's Guide to IV in Options Trading for a fuller breakdown.

Open Interest (OI) Analysis

Total Call OI stands at 1,460.45 lakh contracts against Total Put OI of 1,312.06 lakh contracts, with Call OI running 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 Put OI on the entire chain, by a wide margin, sits at the 23,050 strike, well below current spot. This is the single largest bar on the board and marks a strong support zone. A secondary Put concentration appears at 23,250.
The heaviest Call OI is concentrated at the 23,450 strike, just above current spot, marking the primary resistance zone. Secondary Call concentrations appear further out at 23,850, 23,750 and 23,650.

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 in the 23,350–23,450 band right around current spot, with further notable additions at 23,650 and 23,750. Fresh Put additions are also picking up close to spot in the 23,350–23,400 zone, alongside an older, lighter build-up at 23,050.

This shows both sides actively adding positions right around current spot this week, with Call-side additions extending further out toward 23,650–23,750, while the bulk of the historical Put support at 23,050 hasn't attracted much fresh writing today.

Put-Call Ratio (PCR) Analysis

The current PCR for this expiry is 0.89, 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

Putting the data points together for the September 29 expiry:

1.Structural range: 23,066.10 – 23,591.90, with a tighter 23,228.57 – 23,429.43 zone as the more probable trading band.
2.OI-based support: heaviest Put OI on the chain at 23,050, with a secondary cluster at 23,250.
3.OI-based resistance: heaviest Call OI at 23,450, with secondary zones at 23,650, 23,750 and 23,850.
4.Fresh activity (Change in OI) concentrated close to spot in the 23,350–23,450 band on both sides.
5.PCR: 0.89, mildly cautious-to-neutral bias.

Together, this points to 23,450 as the level to watch on the upside this week, with 23,050 as the stronger, more distant support if the current range gives way.
