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-monitor Let me know if you have any suggestions for improvements!

Hey HN, I am the creator of senatestockwatcher.com and im finally happy to say that the same data that is filed from the House of Representatives is now live for everyone to watch, report against, and use. https://housestockwatcher.com When Senate Stock Watcher was released, the US was in the midst of an election year and after the COVID market crash the SEC had opened some investigations on 3 Senators for insider trading allegations. My interest in politics and finance lead me to build that website, but the number one question I always got was "where is the houses' data?" The…

(* within a few minutes of SEC filing) Currently does it for 1000+ US companies and specifically earnings related filings. By US companies, I mean the ones that are obliged to file SEC filings. This was the result of almost a year long effort and hundreds of prototypes :) It currently auto-publishes for 1000 ish US companies by market cap, relies on 8-K filing as a trigger. e.g. https://www.signalbloom.ai/news/NVDA will take you to NVDA earnings Would be grateful to get some feedback. Especially if you follow a company, check its reports out. Thank you! Some examples:…

I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…

Backstory: I wanted to play with intraday stock data but couldn't find a free dataset anywhere. IEXCloud [1] offers API access to 1-minute granularity intraday historical price data, but I was worried that it could get expensive or unwieldy to build up a substantial dataset via API calls. Plus, IEX gives out their raw data for free. I probably should have just used the IEXTools python library [2] to parse IEX's raw data dumps, but I was working on a Julia project, so it felt more thematically appropriate to build a new tool from scratch. I haven't been actively using InvestorsExchange.jl a…

Hi I'm Ryan, the creator of Tariffstatus.com. I woke up wondering what tariffs were active and what was scheduled. However, when I started searching the web, it was a quagmire of news sites and long articles that didn't give me a simple and clear answer - the government sites were even worse. Also, I imagine they will be constantly changing. I wanted this for myself, but I'm also hopeful it helps others. I plan to keep it up to date. Many of these tariffs are having and will have a significant impact on both consumers and business owners. Trying to bring a bit of order to the chaos! I’d love…
