# nasdaq-symbol-directory

nasdaqlisted.txt + otherlisted.txt (pipe-delimited, daily) from Nasdaq Trader.

  • Type: BULK_FILE · Rights: PUBLIC_ATTRIBUTED · daily (ETag/304 aware).
  • Output: ~11,000 instruments proposals — symbol, cleaned name, venue (Exchange code N/A/P/Z/V → XNYS/XASE/ARCX/BATS/IEXG), ETF flag, security type heuristics (warrants, units, preferred, ADR…). Test issues skipped.
  • Aliases: BRK.B ↔ BRK-B ↔ BRK B (CQS/Nasdaq conventions).
  • Quirk: the last line File Creation Time: … is not data.
