F&O Scanner

What the screener measures

Each stock is scored across the metrics that matter for derivatives traders. IV rank places current implied volatility against its own recent range, so you know whether options are relatively cheap or expensive. OI change shows where fresh positioning is flowing. Volume spike compares today's activity to the 20-day average, catching stocks that are suddenly in play. PCR and max pain give the options-sentiment read for each name.

The unusual-activity scanner flags stocks showing two or more abnormal signals at once — for example a volume spike combined with a large OI change. That combination is often where informed money is moving before the price fully reflects it, which makes it a strong starting point for deeper research.

Filtering and sorting for your strategy

Open the filter panel to set thresholds on IV rank, minimum OI change, minimum volume spike and PCR range, or tick "only unusual activity" to see just the flagged names. Sort any column to rank the universe by what you care about most, then click through to a stock's detail page for its full option chain and fundamentals.

• High IV rank → richer premiums, better for option sellers
• Low IV rank → cheaper options, better for buyers expecting a move
• Volume spike + OI change together → unusual activity worth investigating
• Extreme PCR → potential sentiment reversal
