Capitol Trades tracks the data. Signal Congress tells you which signals actually matter.
Signal Congress is the best alternative to Capitol Trades for investors who need more than a trade browser. Where Capitol Trades shows you the raw disclosure data, Signal Congress adds conviction scoring, bipartisan cluster detection, and AI-generated trade theses to tell you which filings actually matter.
Yes — both platforms pull from the same underlying House and Senate PTR disclosure data. The difference is what's built on top: Capitol Trades provides a clean data browser, while Signal Congress adds a full scoring and intelligence layer including conviction scores, cluster alerts, and committee relevance overlays.
If you're spending time manually evaluating congressional disclosures to decide which ones are worth acting on, Signal Congress automates that judgment layer. Conviction scores, bipartisan cluster alerts, and committee relevance overlays replace the manual research workflow.
Signal Congress PRO is $49/month, with a free tier available for basic access. For Capitol Trades' current pricing, check their site directly.
Signal Congress uses a 0–100 conviction score built from five dimensions: bipartisan cluster overlap, committee relevance, disclosure lag, member historical win rate, and trade size. The score is frozen at filing time so you can track how conviction changed across a member's history. Trades scoring 65+ have historically outperformed the S&P 500 by +12.63% at 180 days.
Conviction scoring, bipartisan clusters, and cascade alerts — all the intelligence Capitol Trades doesn't provide.
