Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year (and a half). I've posted this before, but I've finally open-sourced this entire project, so I thought I'd post it again. Heres the short pitch. The Securities and Exchange Commission (SEC) keeps record of every company in the United States.

- AMA modern alternative to OpenInsider, with more transaction typesFeb 2026 · 13radar.com · ▲6
Hi HN, I've been working on 13radar.com, a site focused on tracking institutional holdings. Today, I’m releasing a beta version of our new Insider Trading Tracker. Like many of you, I've used OpenInsider for years. It's a legendary tool, but the UI hasn't changed in decades, and the data classification can be broad. I wanted to build something that feels modern and digs deeper into the data. How it differs from existing tools (OpenInsider / GuruFocus): Granularity: We parse SEC Form 4 filings to categorize transactions into finer types. Instead of just "Buy/Sell," we try to…
