Each trade is a line of a periodic transaction report filed under the STOCK Act, read from the report itself and linked to it. Three offices publish them, and all three are read here every hour: the House Clerk for representatives, the Senate Office of Public Records for senators, and the Office of Government Ethics for the President, the Vice President and Senate-confirmed officials (OGE Form 278-T). OGE links some officials’ reports and releases the rest on request; only linked reports are here.
The Act requires a report within 45 days of the trade; the lag counts the days from the trade to the day the report became public. Reports give each amount as a range. Amendments are marked and not counted as late; trades a later report withdrew are left out. The President’s reports and some House reports are scans of paper forms: a scanned value that does not read with certainty is shown as not read, never guessed, and the report is one click away. “Since” is the stock’s move from the trade date’s close to the latest daily close.
The same trades are in the OptimistFi MCP server’s get_congress_trades tool, by filer or by stock, for each chamber: connect it. Every House trade is free to download as CSV or JSON, and every trade here can be followed by RSS: the data.
