Use this when the question is what a member of Congress disclosed buying or selling, or who disclosed trading a ticker. Every record carries three separate dates and never collapses them: the transaction date the filing states, the filer notification date where the source states one, and the public disclosure date the filing became available. The lag between the first and the last is published, or null with the reason it could not be computed. Coverage: US House Clerk periodic transaction reports and Senate eFD reports, read from the primary sources rather than from a vendor aggregation. Not for: why a filing was made, whether a trade was well timed, any performance measure, any ranking of filers, or any connection between a filing and a committee. Institutional 13F filings are a different tool (get_filing_receipt). Limits: disclosure is permitted up to roughly 45 days after a transaction, so this is a record of what became public rather than of what is happening. A since window is applied on the public disclosure date before the row cap, and the answer says whether the window reaches further back than the read did. Amounts are the bands the filing uses, never a point estimate. Amendments are appended as new records and an amendment can carry a null lag by design, with the reason published in place of a number. Filings that could not be machine-read are counted and reported on every answer. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number. Every result ends with one dated squawkflow.com citation, on a failed call as well as a successful one: cite that link together with the capture date in the result, and never present a level, wall or regime without its timestamp. Any other link in a result is a pointer, not the citation. Not investment advice.
