Live option-chain snapshot from NSE (no database cache). PCR uses PE OI / CE OI; VPCR uses PE Vol / CE Vol for the nearest expiry. Rows are colour-coded based on a simple bullish/bearish interpretation of PCR. This view reuses the same data as the PCR and Strike Metrics sections.

For each symbol, shows the strikes corresponding to: Highest OI, Highest Change in OI, and Highest Volume on both CE and PE sides (nearest expiry only). The green cell marks the dominant side for that metric. The black rectangle border highlights the strike (CE or PE) that is closest to the spot price. This view reuses the same data as the PCR and Widget sections.

Implied Volatility Skew analysis shows the difference between Call and Put IV at the nearest strike to spot price. Positive skew indicates higher Put IV (bearish sentiment), negative skew indicates higher Call IV (bullish sentiment).

Max Pain strike is calculated as the strike price with the highest total open interest (Calls + Puts). This is the price at which the total value of expiring options would be minimized for the option writers.

Levels use highest Open Interest only inside a 5% band around spot using OTM legs: Support — put OI at strikes from 5% below spot up to (but not including) spot; Resistance — call OI at strikes from just above spot up to 5% above spot. Example: spot ₹1000 → OTM puts: strikes ≥ ₹950 and below spot; OTM calls: strikes above spot up to ₹1050.

Open Interest (OI) spurts show significant changes in open interest for tracked symbols. Data is filtered to show only symbols that are monitored in other dashboard tabs.

Gamma spikes are computed from the already-loaded option-chain (nearest expiry) using Black–Scholes gamma and Open Interest. This tab uses absolute gamma concentration (Calls + Puts) and considers all strikes in the nearest expiry.
