4. Data Availability

  • Trading days only — Data is not available on weekends (Sat/Sun) and NSE holidays
  • Historical depth — Index data typically available from 1999 onwards
  • Report availability — Daily reports are usually available by 6:00 PM IST on trading days
  • No official API — NSE does not provide a documented public API; this library uses web scraping

5. Rate Limiting & Access

NSE websites may:

  • Return HTTP 403 if too many requests are made in quick succession
  • Block IPs temporarily for aggressive scraping
  • Change URL patterns without notice

Recommendations:

  • Add delays between requests (the library adds 1-2 second delays during session warmup)
  • Don’t make more than 1 request per second
  • Cache downloaded data locally
  • Pin your nse-data version to avoid breakage from URL pattern changes
