With over 180 F&O stocks on the NSE, finding the ones actually worth watching on any given day is the hard part. The F&O screener scans the full list and surfaces the outliers — stocks with unusual options activity, sharp open-interest changes, high implied volatility or abnormal volume — so you spend your time on setups, not on scrolling. Every metric is computed from live NSE data and is filterable and sortable, so you can build the exact scan your strategy needs.
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.
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.
