Why free?

Built differently

Historical, not just live

Every dashboard carries EOD history. Sensibull/Opstra/Quantsapp free tiers are deliberately crippled with delays; ours is the opposite.

GEX across 105 F&O underlyings

No competitor in India offers free, historical, all-stock gamma exposure. The four sites that show GEX are live-only, index-only, or paywalled.

News as a first-class signal

News events tagged with category and 1-hour impact, side-by-side with the options positioning on the same page.
