Economical Calendar - how they do it?
From where I can get data about economical events with date and exact time and from where I can import values for this event in real time. For sure from sites like the one from screen shoot. But how they do it? How / from where they get this data?
Not sure, but my guess is one of the larger commercial news distributors, e.g. https://www.refinitiv.com/en/financial-news-services/news-distribution
