Common questions
Is Capitol Trades free?
Yes, the site is free to browse. It is built by 2iQ Research, a data company, and covers the House and the Senate.
Why does The Philosopher Investor only cover the House?
Senate filings live on a separate system that blocks automated reading from most networks. House filings are complete here and refreshed daily. When the Senate becomes readable it will be added.
Is there a free Congress trades page here?
Yes. The free daily page lists the latest House filings and the names bought by the most members over three months, and every public stock page carries the Congress filings on that name.
Can I use both?
Yes, and most people should. Capitol Trades to research a politician or browse the Senate, the desk to see what the filings say about a stock alongside its flow and its chart.
