Every site that covers congressional trading quotes returns from the politician's own entry price. But filings arrive up to 45 days after the trade (median ~26 days in the data), so nobody copying them ever got that price. I built a backtester that buys at the first open after each filing became public.. the earliest moment a real person could act. Fees on, equal position sizes (filings only disclose amount bands, so precise position sizes on other sites are invented).

Data is parsed from the House Clerk and Senate eFD archives back to 2012, refreshed daily. Paper-scan filings we can't parse are counted and shown as a coverage number instead of silently skipped. Free, no signup: https://investingpaths.com/tools/congress
