What Unusual Whales Offers, and What You Actually Need
Unusual Whales packages a lot into one paid subscription: options flow, dark pool prints, congressional trades, corporate insider filings, and more. If you want all of that, the price can make sense. But plenty of traders and researchers only care about one slice, specifically who in Congress is buying or selling, and which corporate insiders are moving their own stock. That data is public by law. The question is just where to find it without paying for a platform built around the rest.
Congressional trades are disclosed under the STOCK Act. Corporate insiders file SEC Form 4 within two business days of a transaction. Neither data set requires a subscription to access. The free tools below cover both cleanly, with different tradeoffs on presentation and speed.
Free Sources for Congressional Trade Data
Capitol Trades is the cleanest free browser for STOCK Act disclosures. It aggregates House and Senate filings, lets you filter by member, party, ticker, or date range, and displays transaction amounts in the disclosed bracket format (the law only requires ranges, not exact dollar amounts). No account is required to browse. The interface is fast and the data is updated regularly.
Quiver Quant offers a free tier that includes congressional trading data alongside other alternative data sets. The free tier has some limitations on historical depth and export, but it works well for spot-checking recent filings. The site also shows aggregate scores and sector breakdowns that can speed up screening.
The official sources exist too. The House Clerk disclosure portal and the Senate financial disclosures site both publish raw filings, but the experience is closer to a document archive than a data tool. PDFs, inconsistent formatting, and no filtering make them slow to use. They are the authoritative source, but they are not built for fast research.
Filing lag matters. Members of Congress have up to 45 days to report a trade under the STOCK Act. The transaction date and the disclosure date can be weeks apart, so what looks like recent activity may reflect a trade from over a month ago.
Free Sources for Corporate Insider Data
SEC EDGAR is the definitive source for Form 4 filings. Every insider trade at a public company, from CEOs buying shares to directors exercising options, must be filed here. The search works, but the interface is dated. Reading raw filings takes practice, and there is no built-in way to filter by trade type, size, or cluster activity.
OpenInsider is a free aggregator built on top of EDGAR. It surfaces Form 4 data with filters for trade type (open market buys are the most significant signal), dollar size, and insider role. Cluster buys, where multiple insiders at the same company buy within a short window, are especially watched. OpenInsider makes those patterns visible without a subscription.
ChartRead includes free congressional and insider trade feeds built around disclosed STOCK Act and Form 4 data. Each entry links to a one-tap chart read that returns the pattern, signal, confirmation trigger, and invalidation level for the ticker in question. It is useful when you want to check the technical picture on a stock right after spotting a notable disclosure, without switching between tools.
Honest Comparison: Free vs. Paid
Paid platforms like Unusual Whales genuinely do more. Options flow and dark pool data are not public, so there is no free equivalent. If you trade around unusual options activity, you need a paid tool. But for disclosed congressional and insider trades, the free options cover the core data because the data itself is already public.
Disclosed does not mean timely. Both STOCK Act and Form 4 filings reflect past transactions. Trading on disclosed insider data is legal (you are reading public filings), but by the time a trade is public, prices may have already moved.
Which Tool to Start With
For congressional trades, start with Capitol Trades. It is the fastest free browser with no account wall. Add Quiver Quant if you want sector scoring or want to cross-reference the filings with other data the site tracks.
For insider trades, OpenInsider covers the filtering that EDGAR lacks. Screen for open market buys above a meaningful dollar threshold, and look for cluster activity. Use EDGAR directly if you need to pull the raw filing or verify a specific transaction.
If your workflow involves checking the chart on a ticker after spotting a filing, a tool that combines the feed with chart analysis saves a step. The underlying data across all these free options comes from the same public disclosures. The difference between them is presentation, speed, and what else sits alongside the filing.
