Every structured row in ProBors is meant to be checked against the original filing on an official government site. When the upstream source provides a stable URL, the signed-in dashboard shows Open original disclosure on congressional trades and Open original SEC filing on whale insider rows—both open in a new tab on House Clerk, Senate eFD, or SEC hosts only. Use that link as your verification step before you add a ticker to a watchlist, quote a politician in a draft, or share a screenshot. This is research context, not investment advice.
Quick answer
Click any row in Trades or Whales, read the disclosure context window, then look under Timeline & source for Open original disclosure ↗ or Open original SEC filing ↗. Compare transaction date, ticker spelling, amount bracket or share count, and asset type on the PDF or HTML form. If the link is missing, open the same member or issuer through House Financial Disclosure, Senate eFD, or SEC EDGAR manually—ProBors still shows parsed fields, but you should not treat a row as publication-ready without a source match.
Why source links matter for disclosure research
Headlines often compress a statutory amount bracket into “bought $50k of NVDA.” The signed form may show a range, a spouse account, an option line, or an amended date. ProBors normalizes fields for sorting and signal scoring; the .gov document is what members and insiders attested to.
Source links also clarify filing lag: the trade date on the form is when activity occurred; the filing date is when the public record updated. Your notes should cite both—and the original link is how you prove which is which when someone challenges a table.
Step 1: Open the context window from Trades or Whales
Start on the feed that matches your question:
- Sign in at probors.com and open Trades for House and Senate STOCK Act rows, or Whales for large Form 4-style insider prints.
- Narrow with politician, ticker, or date chips if you already know the target row—see the Trades tab guide or Whales tab guide.
- Click the row once. The context window loads hero fields, timeline dates, signal reasons when present, and the price chart.
The filing link lives in the left column, not in the table itself—train yourself to open the panel before you copy a field into Slack or a doc.
Step 2: Use Open original disclosure on congressional rows
For congress trades, ProBors labels the card Timeline & source and lists traded and filed dates when ingest preserved them. Below those rows, Open original disclosure ↗ appears only when ProBors has a verified HTTPS URL on an allowed host (House Clerk or Senate eFD).
On the official page:
- Confirm member name and chamber match the ProBors row.
- Match ticker or issuer description—some rows use fund names or placeholders when no liquid symbol exists.
- Read the statutory amount bracket or narrative line; do not infer exact dollars from ProBors estimated value alone.
- Note amended or supplemental markers on the source site; ProBors may show the latest normalized row while an older PDF still circulates on social media.
For a full pre-share checklist, pair this step with how to verify congressional trade disclosures before sharing.
Step 3: Use Open original SEC filing on insider / whale rows
Whale rows use the same modal layout with insider-specific hero fields (reporting person, title, transaction code). Open original SEC filing ↗ points to SEC EDGAR when a compliant URL is on the record.
Cross-check:
- Transaction code letters (open-market purchase vs sale, plan-related codes, etc.).
- Share quantity and price on the form vs the table—notional in ProBors is derived for sorting, not a substitute for the filed line.
- Reporting owner vs derivative lines when multiple tables appear on one Form 4.
When you research both chambers and insiders on one symbol, keep the congress PDF and Form 4 open in separate tabs and compare timing—see how to combine congress and insider research.
Step 4: When no source link appears
ProBors hides the button rather than guessing a URL. Common reasons:
- The upstream batch did not include a per-row link yet.
- The host is outside the allowlist (only official disclosure domains are shown).
- The row is a normalized duplicate of an earlier ingest pass.
What to do:
- Note the record ID shown in filing details if you need support context.
- Search the politician on House or Senate eFD using filed date and amount bracket as anchors.
- For insiders, search EDGAR by issuer ticker and filing date.
- Check probors.com/status if many rows on one day lack links—ingest may be mid-batch.
Missing link does not mean the trade is fake; it means you must locate the PDF before publication.
Step 5: Fold verification into your daily workflow
A repeatable five-minute habit:
- Filter Trades to Recent first (column header or More filters preset).
- Open the top three rows that pass your signal or amount rules.
- Click Open original disclosure on each; log traded vs filed dates in your notes.
- Only then add politicians or tickers to your watchlist.
- End the session by spot-checking one Whales row the same way when you cover insider overlap.
Journalists and newsletter writers can treat the link as the citation anchor; retail researchers can use it to avoid acting on misread dates. Neither path requires treating signal scores as forecasts.
What this does not prove
Opening the official form confirms what was disclosed, not why the trade happened, whether it was profitable, or whether anyone had non-public information. Links do not guarantee ProBors parsed every footnote correctly—when a field disagrees with the PDF, trust the PDF and file a support note with the record ID.
Amended filings can arrive after you first verified a row. Re-open the source link when a politician profile shows a newer filed date for the same transaction window.
FAQ
Does every ProBors row include a source link?
No. The button renders only when a validated official URL is on the record. Use manual House, Senate, or EDGAR search when it is absent.
Are links safe to click?
ProBors only surfaces HTTPS URLs on House Clerk, Senate eFD, and SEC hostnames. They open in a new tab with standard browser protections.
Can I share the official link instead of a ProBors screenshot?
Yes—linking the .gov filing is often clearer for readers than a cropped table. Mention that you verified dates on the form.
Do source links work on the public marketing site?
Detailed filing links appear in the signed-in disclosure context window after you click a row. Marketing pages describe the feature; verification happens inside the dashboard.
How does this relate to SEC EDGAR search alone?
EDGAR is authoritative for issuers and insiders; it does not replace House and Senate STOCK Act portals for members of Congress. ProBors routes you to the right domain per row type—see SEC EDGAR vs ProBors workflow for when to start in each tool.
