# Methodology

**Last updated: September 20, 2026.**

Glasshouse standardizes public STOCK Act periodic transaction reports (PTRs) filed by members of the U.S. House and Senate.

## Sources

- U.S. House Clerk financial disclosure filings
- U.S. Senate public financial disclosure search

We are not affiliated with either office.

## What we ingest

- Equity buys and sells (and related transaction types when present in the filing)
- Reported amount ranges (filings rarely state exact dollars)
- Trade dates and disclosure / notification dates
- Member, chamber, party, and mapped ticker when available

## Timing

Under the STOCK Act, members generally must disclose qualifying trades within 45 days. Glasshouse publishes filings after they appear on the official disclosure sites, typically within a few hours of becoming public, not at trade execution time.

## Amounts

Disclosures use ranges (for example `$1,001-$15,000`). When we show totals, we sum range floors and ceilings separately. We do not invent midpoints or portfolio NAVs.

## Price after the trade

Price context compares the stored transaction-day price with a later market close. That move is **not** a member’s realized return, position size, or proof of intent.

## Limits

- Filings can be amended or corrected
- Private or unmapped assets may appear in counts but lack priced rows
- Coverage is only as complete as the public PTR record
- Data may be delayed, incomplete, or contain errors

Week-specific research freezes its own coverage window and price snapshot. See each article's methodology section.
