class quantlab.dataset.config.MassiveNewsConfig(*, zarr_file_path, start_date=None, end_date=None, symbols=None, kwargs=None, resample_freq=None, resample_how=None, name=None, raw_data_dir_path, market='us_equity', frequency='1d', vendor='massive', table='sep', permatickers=None, roster_universe=None, category_filter='default', massive_dir, ticker_map_path)[source]#

Bases: MassiveRestPanelConfig

Config of the Massive news count and sentiment panel on the permaticker axis (#357).

Massive’s news articles (the REST raw tier rest/news under massive_dir) are counted per security and trading day, each article placed through the Ticker map at ticker_map_path, on SEP’s trading calendar. raw_data_dir_path is Sharadar’s raw tier: SEP’s dates are the calendar and SEP’s TICKERS rows the universe, whose fields work as for a price panel (the default is domestic common stock).
