Symbol and ISIN history

Every NSE symbol and ISIN a company has traded under, with the first and last trading day each was observed — use it to map old tickers (e.g. a renamed company) to today's symbol. Accepts a current or former symbol, a BSE code or an ISIN. A symbol always resolves to the company that holds it now (or held it last); if a ticker was ever reused by a different company, reach the earlier holder by its ISIN or BSE code (both are unique) and filter its spells by date. Coverage starts 2016-01-01 and is refreshed every trading day; companies listed only on BSE have no NSE symbol spells.
