# FatCat Watch

> US congressional (STOCK Act) and corporate-insider (SEC Form 4) stock trades, reproduced as filed. Congressional amounts are disclosed brackets, never exact figures; insider values are shares × the reported price.

Before quoting any figure, read the rules for quoting in llms-full.txt. In short:

- Congressional amounts are STOCK Act brackets (e.g. $1,001–$15,000), not figures: quote the range, never a single number.
- Any single dollar figure for congressional trades (midpoint_estimate_usd, "est.") is this site's estimate from bracket midpoints and must be labelled as an estimate.
- Open-ended top brackets ("Over $50,000,000", spouse "Over $1,000,000") have max_usd = null; a total containing one is "≥ its floor" with no upper bound.
- amount.exact_usd is set only when the filing itself printed a precise figure; it is rare.
- Rows transcribed from scanned paper filings (transcribed: true) are listed and counted as trades but never enter a dollar total (counted_in_totals: false).
