Key Strike Levels
The open‑interest landscape clusters around the 680‑690 put corridor and the 770‑800 call corridor, indicating a likely support zone near ₹680‑690 and resistance near ₹770‑800 that have historically acted as psychological barriers and liquidity magnets for institutional participants. The ATM strike at ₹685.3 sits just below the put support band, suggesting that market participants view the downside as relatively constrained and therefore the market perceives the downside as relatively limited in scope. The implied price range derived from the concentration of OI spans roughly ₹680 to ₹800, framing the short‑term directional bias and suggests that traders are pricing a modest upside potential within this band.
OI Buildup Activity
On the call side, fresh OI adds of 700 (+₹17,93,350), 770 (+₹11,28,400) and 800 (+₹10,49,100) reflect incremental positioning by sellers at higher strikes. Conversely, the put side sees notable additions at 680 (+₹14,47,550), 670 (+₹10,97,200) and 690 (+₹10,13,350), indicating aggressive writing of downside protection. These accumulation patterns illustrate that market makers are expanding their exposure around the identified support and resistance bands.
Volatility Read
The at‑the‑money implied volatility stands at 20.1 %, modestly above the recent historical average for the underlying. The skew is bearish, with out‑of‑the‑money puts priced higher than calls, implying a market tilt toward downside risk premia.
Key OI Levels
The highest call OI of 1,000 contracts sits at the 0 strike, while the highest put OI of 1,000 contracts also resides at the 0 strike, marking these levels as the dominant concentration points.
