Key Strike Levels
The open‑interest (OI) profile clusters tightly around the 720‑720 ₹ put and the 760‑₹ call strikes, suggesting a probable trading range of roughly 720 ₹ to 760 ₹ for the underlying. The 720 ₹ put carries the largest PE OI (1,000 contracts), acting as a strong support wall, while the 760 ₹ call holds the most CE OI (1,000 contracts), forming a clear resistance barrier. The market’s implied volatility contour, anchored by these concentration points, signals that price excursions beyond this band will likely require a material shift in sentiment or a catalyst event.
OI Buildup Activity
During the latest trading session, fresh CE OI accumulates at 730 ₹ (+2 contracts, 37,250 ₹), 760 ₹ (+1 contract, 104,000 ₹), and 790 ₹ (+0 contract, 96,200 ₹), indicating that option writers are adding positions near and above the resistance zone. On the PE side, new OI appears at 720 ₹ (+19 contracts, 1,989,650 ₹), 710 ₹ (+7 contracts, 720,850 ₹), and a modest addition at 820 ₹ (+0 contract, 650 ₹), reflecting a defensive stance below the support level. The distribution of these additions points to market participants reinforcing existing bands rather than expanding them.
Volatility Read
The at‑the‑money implied volatility stands at 17.92 %, consistent with a moderate risk environment for the underlying. The observed volatility skew is bearish, with out‑of‑the‑money puts priced higher than equivalent calls, implying a tilt toward downside protection.
Key OI Levels
The strikes with the highest open interest are 760 ₹ for calls (1,000 contracts) and 720 ₹ for puts (1,000 contracts).
