The ticker on that venue, or the value in that scheme. An ISIN, sid, cid or share-class FIGI answers for the main listing only; reference/listings lists the others. See Identifying an instrument.

Query Params

Inclusive start of the returned date window. Format: YYYY-MM-DD.

Also selects the instrument: the ticker resolves to the listing that held it on the exchange in the URL path on this date. To retrieve a delisted or renamed company, use its former exchange and ticker with a from_date from when it was listed. An identifier path (/stock/isin|figi|sid|cid/<value>/…) resolves at this date too. The instrument block in the response names the company the data belongs to.
