The one honest gap
The only market data we don't have is NSE futures & options minute-bars from Nov 2024 to early 2026 — a window sold only by paid vendors, and one we flag in every audit rather than paper over. Everything else here was built from public and self-collected sources, cleaned in-house. We'd rather show you the hole than hide it.
