Key Strike Levels
The options market shows a tight concentration of open interest (OI) around the ₹195‑₹200 band. The highest call OI sits at the ₹120 strike, which currently acts as a resistance level, while the largest put OI also clusters at the ₹120 strike, providing a support cushion. Implied‑volatility‑based pricing suggests an expected price range roughly between ₹155 and ₹240 for the September 29 expiry.
OI Buildup Activity
Fresh OI adds are evident on the put side, with the ₹200 strike absorbing an additional 18,800 contracts and the ₹195 strike gaining 4,700 contracts, indicating that market participants are strengthening downside exposure. No new significant builds appear on the call side, implying that sellers are not aggressively adding to bullish positions at this time. The accumulation of put OI near the spot level reflects a defensive stance by market makers aiming to hedge against potential downside moves.
Volatility Read
The at‑the‑money implied volatility stands at 27.93%, a level that aligns with the underlying’s recent price volatility. Skew is neutral, indicating no pronounced bias toward either calls or puts across the strike spectrum.
