Is there a dataset of US congressional stock trades?

What the congressional stock trades data covers

The US congressional stock trades dataset records what members of Congress buy and sell, from their public disclosures, so you can see which politicians traded which tickers and when. It pairs with the market data you need to act on it: 16,000+ US stocks that have traded on NYSE and Nasdaq since 2000, delisted names included, plus 231 ETFs and 139 futures markets with every contract since 2007. Options traders get point-in-time gamma exposure for 11,200+ stocks, ETFs and the major indexes since 2010, each row carrying the gamma flip, call wall, put wall, net call and put gamma, open interest and the put/call ratio. COT since 1986, 13F holdings, SEC fundamentals as filed and 18,000+ macro series complete the picture.

How to get it: CSV, API and MCP

Three routes, one catalog at finzdata.com/datasets.

• CSV downloads — pull the congress trades and any market history into pandas, Excel or your research stack.
• REST API at https://api.finzdata.com — programmatic access for quants and pipelines.
• MCP server at https://api.finzdata.com/mcp — connect ChatGPT, Claude or any AI agent and ask in plain English.

Server-side backtests run on the same data, and free indicators for TradingView, thinkorswim and NinjaTrader are at finzdata.com/trading-platform-plugins.

Why it avoids backtest pitfalls

Most congress trade studies fail on bad market data, not bad ideas. FinzData is point-in-time, so nothing leaks in from the future:

• Survivorship-free stocks — delisted companies are included, so following a politician's losing pick shows the real result.
• SEC fundamentals as filed — no look-ahead bias from restated numbers.
• Macro vintages kept — 18,000+ series store every release, so CPI or jobs revisions never rewrite your backtest.
• Real futures contracts — continuous series keep the roll dates and every individual contract is included, so a backtest trades what actually existed.

What it costs and the free tier

Market data is a one-time purchase at finzdata.com/shop: one futures market with its full history is $39, bought once and yours. The congress trades dataset sits in the same catalog.
