Live Greeks Panel
Key Strike Levels
The open‑interest cluster centres around the 165/170 call strikes and the 152.5/160 put strikes, forming a tentative support‑resistance corridor of ₹152‑₹170. The spot price of ₹160.33 sits near the upper edge of the put cluster and just below the call concentration, suggesting that buying pressure may be capped while downside protection remains solid. This range also aligns with the at‑the‑money implied‑volatility surface, indicating that market participants price the underlying within a relatively tight 8‑point band as expiry draws nearer.
OI Buildup Activity
Fresh call open‑interest adds of 175 (+16,54,350), 170 (+3,56,700) and 165 (+3,44,400) indicate that market makers are enlarging short positions near the resistance zone, with the bulk of new contracts posted at the 175 strike to hedge potential upside moves. On the put side, the 152.5 (+9,71,700), 160 (+4,18,200) and 155 (+2,76,750) strikes show incremental long exposure supporting the identified floor, and the magnitude of these additions reflects a deliberate effort to preserve downside risk. The symmetrical OI inflows suggest a neutral stance with emphasis on range‑bound trading as expiry approaches, while the concentration of fresh contracts at adjacent strikes points to a cautious positioning strategy.
Volatility Read
The at‑the‑money implied volatility stands at 31.24 %, reflecting moderate premium levels across the straddle. A bearish skew implies that out‑of‑the‑money puts carry relatively higher implied volatility than comparable calls, highlighting market bias toward downside protection.
Key OI Levels
The largest call open interest resides at the 165 strike, while the largest put open interest concentrates at the 152.5 strike.
