Live Greeks Panel
Key Strike Levels
The open‑interest (OI) profile shows a tight band between ₹400 and ₹410, where the bulk of contracts cluster. The CE side peaks at the ₹410 strike with 220 contracts, acting as a resistance ceiling, while the PE side mirrors this with 220 contracts at the ₹400 strike, forming a support floor. Consequently, the market is pricing the underlying to trade in a roughly ₹400‑₹410 range through the September expiry.
OI Buildup Activity
Recent data reveal a notable influx of fresh OI on the call side: the ₹450 strike accrues 450 contracts (+7 % over the prior day), supplemented by 410 and 400 strikes adding 4 % each (≈35,000 and 15,000 contracts respectively). On the put side, the ₹400 strike gains 1 % (≈150,000 contracts), while the 410 and 405 strikes collect 42,500 and 22,500 contracts respectively. The accumulation of new OI at these strikes suggests that option writers are positioning to collect premium near the current price, reinforcing the observed resistance‑support structure.
Volatility Read
The at‑the‑money implied volatility stands at 21.14 %, indicating modest expectation of price movement over the remaining 25 days to expiry. The volatility skew is bearish, with out‑of‑the‑money calls priced higher relative to puts, reflecting market bias toward downside risk.
Key OI Levels
The highest open‑interest concentrations reside at the ₹410 call (220 contracts) and the ₹400 put (220 contracts).
