Data Sources and Compliance
Where the numbers in Bourse come from, how fresh they are, and what Bourse is not.
Not a government app
Bourse is an independent service. It is not a government app, does not represent any government body, agency or political party, and is not affiliated with or endorsed by the U.S. Congress, the SEC, any central bank, the National Bank of Poland, Statistics Poland (GUS), the Warsaw Stock Exchange or the Polish Ministry of Finance.
Sources
- Congress trades: disclosures filed under the STOCK Act with the U.S. House and the U.S. Senate, collected through a third-party data provider (Bargo).
- Insider trades and fund holdings: SEC Form 4 and Form 13F filings published on SEC EDGAR, partly collected through a third-party data provider (Form4API).
- ESPI reports: current reports of companies listed on the Warsaw Stock Exchange, taken from the public feed of Bankier.pl.
- Central bank and regulator news: public websites and RSS feeds of the Federal Reserve, European Central Bank, Bank of England, Bank of Japan, Swiss National Bank, Narodowy Bank Polski and the SEC.

Not investment advice
