Sector net flow · all parseable filings
Buy filings extend right, sell filings extend left. Full half-width = 1362 filings.
What counts: parseable e-filed PTRs only; paper filings are excluded · skipped, not guessed. Sector enrichment is still partial, so unclassified filings appear under "Other" rather than being guessed into a sector.
Most-filed tickers · 30 days
Split bar shows buy vs. sell share of filings in the name.
Popular ≠ signal: balanced flow in a heavily filed name carries no direction. Volume alone never clears our bar.
Corroboration clusters · same issuer, tight window
Multiple members filing the same side of the same name within a tight window · the pattern most likely to become a signal.
4 members · sell side · 16-day window. Filed range across the cluster: $796,006 to $1,665,000 · brackets, never point guesses.
Watch on feed →3 members · sell side · 21-day window. Filed range across the cluster: $66,003 to $165,000 · brackets, never point guesses.
Watch on feed →Why clusters and not leaderboards: one member buying is a datapoint; several members converging is a pattern. Clusters are what our corroboration input actually measures.
