Data sources provide data in two primary ways: 1. streaming realtime data - from the moment you connect to the source forward in time 2. backfill data - historical data from some period in time prior to the moment you connect to the feed. You can typically tell the feed how much backfill data you want (e.g. the last 6 months), up to some maximum limit imposed by the provider
