I invest my own money in various european midcaps with a value approach (deep dive in the fundamental analysis and understanding of the companies I invest in).
Early 2017, I launched LesTransactions.fr to automatically retrieve from the French Market Authority website the insider trading reports (déclarations de dirigeants) and publish them in a single, simple and easy to use csv format (instead of numerous pdf files). Users can also subscribe to email alerts for new insider trading reports on a given stocks, and add threshold floors (i.e. only be informed if the transaction is over N% of the market cap).
The full database is also available through an API, and the source code of the project was shared on github.
As of 2020, the website is not maintained any more.
