Options Screener
Cross-symbol contract rankings from the latest persisted NSE option-chain snapshots.
How to read these numbers
Price/OI buildup is a mechanical classification, not a signal. Greeks are calculated locally from NSE IV. Premium activity is LTP multiplied by reported volume — a ranking proxy, not rupee turnover. The exchange market lot is now stored, but converting this to cash also requires knowing that the option-chain feed counts volume in contracts rather than units, which has not been verified against a live chain; it stays a proxy until it is. Contract-level IV change is not shown because historical contract IV snapshots are not stored; highest and lowest current IV is shown honestly instead. Percentage screens are dominated by contracts with a tiny starting base; the minimum OI floor keeps them to contracts that already carry positioning.

Underlying sentiment — PCR & max pain
PCR is total puts divided by total calls across every persisted strike of that expiry. The two columns use different conventions on purpose: the OI-based one reads accumulated open positioning, the volume-based one reads the session's traded flow, and they legitimately disagree. Max pain is the strike minimizing option writers' total intrinsic payout if the underlying settled there — a mechanical calculation from real OI, descriptive of current positioning, not a price prediction.
