FNO Ninja — Screener + Indicator

We handle the data and do the heavy lifting so you can focus on finding a fitting trade.

FNO Ninja reads option-chain OI across 200+ NSE F&O symbols and maps likely support and resistance zones.

Call clusters act as resistance. Heavy Call OI at a strike means the market is positioning for a ceiling.

Put clusters act as support. Heavy Put OI means traders are defending a floor.

Strike mapping. Symbols at or near OI clusters show up in the screener so you act on context, not just a chart.
