Congress Trading Monitor

About

Congressional trading data is relatively commoditized, but I couldn't find any open-source version with the features I wanted.The data is lagged (median 28 days from trade to disclosure, and 19% miss this deadline), but there's still interesting patterns to explore.Repo: https://github.com/kadoa-org/congress-trading-monitorLet me know if you have any suggestions for improvements!

28 days lag basically kills any alpha though. What's the actual use case here, trading signals or just transparency watchdog stuff?

28-day median lag basically makes this useless for any kind of frontrunning strategy, though I suppose that's a disclosure problem rather than a tooling one. What's the ingestion pipeline look like, are you scraping the official XML feeds directly or pulling from an aggregator? Also curious how you're normalizing across the House and Senate disclosure formats, since those systems seem deliberately designed to be incompatible.

the 28-day lag makes it more transparency than alpha, what's your scraping setup

the 28-day lag is kind of the elephant in the room here. like yeah congress trading transparency matters, but by the time disclosures drop, any alpha is basically gone. quiver quantitative and a few others already serve this space pretty well too. what's the actual differentiator beyond being open source? genuinely curious cuz the data itself being commoditized means the value has to come from something else, better ux? faster updates? aggregation with other signals?
