How we do it
Where trades come from
Members of the House must report stock trades in a "periodic transaction report". The House Clerk posts these for free. We read the Clerk's yearly list, open each new report, and read its rows.
Scanned paper reports, and any row we can't read cleanly, are skipped. We never guess.
How we pick one
We look at purchases of listed stocks, at least two weeks old, so there is a result to show. Bigger filed amounts and newer filings come first. We don't look at party to pick a trade.
One rule uses party: over any 7 days, Democrat and Republican receipts stay within one of each other. If a pick would break that, we take the next trade instead.
The numbers
The amount is the range on the filing. The stock's change runs from its first close on or after the trade date to the latest close. The S&P 500 is measured over the exact same days, using SPY. Every receipt page shows the math.
A report is due no later than 45 days after the trade (the STOCK Act). Days late = filed date − trade date − 45.
Checks
Code checks every number against the filing and the prices. Then two separate AI reviews check it again. If any check is unsure, we skip that trade.
Senate
For now we cover the House only. The Senate's site asks each visitor to accept terms before searching, so we don't collect from it automatically.
Not financial advice. Facts from public filings.
