Visualisation of Insider Trades, Python, SEC-Api.io

- Reed Hastings (CEO, Netflix) sold $15M of his shares 2 days before a class action lawsuit hit the company and the stock crashed - Mark Zuckerberg (CEO, Facebook) sold $296M of his shares before the stock plunged I was curious to see if I can discover patterns using SEC filings of type 4 (changes in ownership, aka insider trades) and developed a Python app to do so. Do you think that's a path worth exploring further? Maybe even backtesting and developing an algo to trade on signals derived from SEC filings? Did anyone already test a similar approach using SEC filings as trading signals?
