quantlab.dataset.sharadar.tables.tickers_snapshot_file(vendor_root, pulled_at)[source]#

Return the path of the TICKERS snapshot of a pull, beside tickers.parquet.

A TICKERS pull replaces tickers.parquet; the snapshot keeps that pull’s copy, so a raw file pulled in the same run can later be mapped with the tickers the vendor used when it was pulled.

Examples

>>> tickers_snapshot_file("/d/sharadar", datetime(2024, 1, 11, 8, 30)).name
'snapshot_20240111T083000000000.parquet'
