Key Strike Levels
The highest open interest sits at the 200 strike for both calls and puts, marking a strong resistance and support band respectively. The concentration suggests an implied price corridor roughly between ₹200 and ₹200, anchoring market sentiment. Additional notable OI clusters appear around ₹380‑420 call strikes and ₹350‑400 put strikes, extending the expected range. The 32.93% IV translates to an expected 30‑day price movement of roughly ±₹120 around the spot, reinforcing the ₹200‑₹380 band as the most probable trading interval.
OI Buildup Activity
Call open interest adds of 1,57,500 contracts at ₹380, 1,38,750 at ₹420 and 1,35,000 at ₹400 indicate significant new long exposure in the upper band. Put open interest adds of 2,30,625 contracts at ₹350, 1,91,250 at ₹380 and 84,375 at ₹400 reflect fresh short protection nearer the lower band. The influx of contracts points to market participants positioning ahead of the September expiry, with writers likely accommodating the elevated demand. The OI represents a bias toward the upper range, with call additions outweighing put additions by 1.5 contracts.
Volatility Read
The at‑the‑money implied volatility stands at 32.93%, implying moderate price turbulence. The volatility skew is bearish, indicating higher implied volatility for lower strikes relative to higher strikes.
Key OI Levels
