Why Is Everything Free?
Community First
We believe retail traders deserve access to professional-grade tools. We're building in public with the community, not against it.
Sustainable Revenue
We earn from optional broker affiliate partnerships. We recommend tools we believe in. Your success benefits us too.
Open Development
You can see what we're building, contribute ideas, and help shape the future of the platform. This is a public project.
What Traders Are Using
Questions?
Will this stay free?
Right now, yes -- no paywalls, no tiers, nothing gated. Running the servers and data feeds behind it costs real money though, so "free forever, no matter what" isn't a promise we can honestly make. If you find it useful, optional support is what keeps it free for everyone else too.
Is this data real?
100% real market data from Yahoo Finance. Historical OHLC bars with actual trading volumes. No synthetic data.
How do you make money?
We earn affiliate commissions when you open a trading account through our platform. You never pay extra - your broker just gives us a commission.
Can I use this commercially?
Yes! You can use the platform for personal trading, bot development, or even commercial applications. Check our terms for details.
Want a Congress Trade Alert in Your Inbox?
The congress-trades browser above is, and stays, free. If you'd rather get an email than check the page, Congress Trading Alerts is a separate paid add-on: save filters by ticker, member, or chamber and get a digest when something new is disclosed. Free weekly digest available too — no card required.

Servers, market data, and the time to keep this maintained all cost real money. Everything above stays free either way -- but if this has saved you time or made you money, a small optional contribution helps keep it running and free for the next trader too.
