AI AnalysisGenerated daily after market close · AI-powered

Key Strike Levels

Immediate resistance sits at ₹1900, home to peak call OI and a major magnet for call writers. Strong support emerges at ₹1800, where put OI is heaviest, backed by robust put writing. The implied range is boxed between ₹1800 and ₹1900, with secondary resistance at ₹2020 now gaining traction.

OI Buildup Activity

Fresh long calls are building at ₹1900, ₹2020, and ₹1820, suggesting aggressive call buyers anticipate upside, especially at the ₹1900 hurdle. On the put side, substantial OI additions at ₹1800 and ₹1880 signal strong defensive positioning by put writers protecting downside. Notably, the rise in OI at ₹1900 in both puts and calls points to potential hedging or two-way battles near this pivotal strike.

Volatility Read

ATM IV holds at a rich 32.46%, reflecting elevated uncertainty and pricing in event risk. The bearish skew confirms put demand dominance, with traders leaning on downside protection despite fresh long calls at elevated strikes.

Strategy Implication

Bias tilts cautiously bearish, with writers favoring downside protection below ₹1880 and fresh longs testing resistance near ₹1900 and beyond.
