Tab 1 · Holders
The Holders tab opens on Overview - pie chart, insider activity chart, top-10 ranked. Three more sub-tabs underneath: Insiders for the executive cap table, Institutions for the 13F-style ranking, Funds for the ETF/fund concentration view.
The cap table from inside the building. Columns: Name · Position · Shares Owned · % Owned · Since. Share counts are sourced from the most recent Form 4 filing, with a fallback to the key-executives data feed.
13F-style aggregate. Columns: Name · Shares · % Owned · Change · Report Date. Change is colour-coded - green/red - so quarter-over-quarter rotation jumps out without sorting.
Mutual funds and ETFs. Adds a Portfolio % column - concentration inside the fund itself. Useful for spotting which themed ETFs are over-indexing on the name.

Tab 2 · Trades
The Trades tab splits the data into the two filings that carry it: Form 4 from the SEC for insiders, STOCK Act disclosures for members of Congress and their household. Both surface the same way - sortable, paginated, joined to executive position on the insider side and to chamber on the congressional side.

Marker legend
The dots on the chart aren't decoration. Each filing source maps to a distinct marker colour - these are them. The y-coordinate is the closest closing price within ±3 days of the transaction date (handles weekends), so a marker sits at the actual fill price the insider got.
Form 4 code P (purchase) or A (grant). Open-market purchases by officers, directors, 10%+ owners - strongest when clustered.
Form 4 code S. We don't strip 10b5-1 sales - they're still data, just weighted differently. Discretionary sales are the louder signal.
STOCK Act disclosure, transactionType containing "purchase". Tagged with chamber (House / Senate) so you can spot committee context.
STOCK Act sale. Owner field tells you whether it's the member, spouse, dependent, or joint - the spouse trades tend to lead.
