Key Strike Levels
The call open interest peaks at the 125‑strike with 0 contracts, acting as a clear resistance point for price advances. The put open interest mirrors this concentration at the same 125‑strike, providing a corresponding support level beneath current market levels. Combined open interest at these strikes suggests an implied price corridor roughly between ₹120 and ₹130 for the September expiry.
OI Buildup Activity
Fresh call open interest adds nine contracts at the 235‑strike (valued at ₹56,250), one contract at 245 (₹89,000) and one contract at 250 (₹41,750), indicating that writers are incrementally building exposure on the upside despite the proximity to the spot price. On the put side, additions total 90,000 contracts at the 235‑strike, 67,500 contracts at the 220‑strike and 40,500 contracts at the 222.5‑strike, reflecting a notable accumulation of protective positions around the current market level. Overall OI growth reflects active positioning by market participants ahead of the expiry, as they adjust delta exposures and hedge existing portfolios.
Volatility Read
The at‑the‑money implied volatility stands at 13.76%, which is modest for the sector and suggests relatively low premium pricing. The volatility skew is bearish, indicating higher implied volatility on the downside strikes and a market bias toward downward price movement.
Key OI Levels
The highest call open interest concentrates at the 125‑strike, while the highest put open interest also clusters at the 125‑strike, underscoring these levels as pivotal resistance and support zones for traders in the market.
