Key Strike Levels
The open‑interest cluster currently centers on the 100‑strike for both calls and puts, framing an implied price corridor roughly between ₹145 and ₹170. The 100‑strike call OI of 100 contracts acts as a near‑term resistance level in the short term ahead of the November expiry in the prevailing market context. Conversely, the 100‑strike put OI of 100 contracts provides a comparable support cushion for the upcoming cycle within the same horizon.
OI Buildup Activity
Fresh call OI adds of 3,44,350 at ₹175, 3,15,950 at ₹170 and 2,69,800 at ₹177.5 signal writers reinforcing the upper band of the range as market participants. These additions represent a net long call exposure, with the largest incremental build at the ₹175 strike, suggesting anticipation of a modest rally to capture potential upside. On the put side, new OI of 2,41,400 at ₹145, 1,84,600 at ₹160 and 1,45,550 at ₹150 indicates put writers staking near‑term downside protection as part of hedging strategy, given current price dynamics.
Volatility Read
The at‑the‑money implied volatility stands at 27.12%, reflecting moderate premium levels relative to recent historical averages and relative to sector peers and comparable to peers today. Skew remains neutral, indicating no pronounced bias toward call or put demand across the observed strikes across all maturities.
Key OI Levels
The highest open interest of 100 contracts each sits at the 100‑strike for both calls and puts, marking the tightest concentration point as of the latest market snapshot.
