NSE Scanner

Scan the NSE equity market for top movers, volume spikes, and price extremes using NSE's publicly accessible JSON APIs — no API key required.

When to Use

  • User asks for today's top gainers or losers on NSE
  • User wants stocks hitting 52-week highs or lows
  • User asks for unusual volume activity or surge stocks
  • User wants a quick market overview (advances vs declines)
  • User asks "which Nifty 50 stocks are up/down today?"

Examples

"Show me today's top 5 Nifty gainers" → Fetch gainers API, filter NIFTY data, sort by pChange descending, display top 5 with symbol, LTP, and % change.

"Any stocks hitting 52-week highs today?" → Fetch high52 endpoint and list symbols with their current price and % change.

"How is the overall market today — more advances or declines?" → Fetch pre-open market data, group by positive/negative pChange, show counts.

Cautions

  • NSE APIs require a session cookie obtained by first visiting https://www.nseindia.com — always initialize the session before API calls
  • NSE may rate-limit or block automated requests; add a small delay between calls if running bulk scans
  • Market data is available only during trading hours (Mon–Fri, 9:15 AM – 3:30 PM IST)
  • API endpoints and response structure may change — verify against NSE website if calls fail
