About NiftyLens
Free, end-of-day options analytics for Indian retail traders.
Why free?
Sensibull, Opstra, Quantsapp — the established names — all charge ₹800–2,950/month and deliberately cripple their free tiers with delayed data. NiftyLens inverts that: every feature is free, no login, EOD derived metrics (GEX, OI walls, max pain, PCR, IV skew, flow) across all 94 F&O stocks.
What it shows
- End-of-day option chain metrics — GEX, max pain, PCR, IV skew, net delta flow
- OI wall, CE/PE build-unwind verdict, options flow heatmaps
- News events with category + 1-hour impact attribution
- Premarket snapshot (GIFT Nifty, US close, Asia open)
What it does not show
- Real-time tick data (NSE charges ₹1.2L/yr/medium for 15-min delayed; see pricing)
- Prescriptive buy/sell calls (would require SEBI Research Analyst registration)
- Raw option chain tables per strike (we show aggregates only)
