How is European insider trading data different from US SEC Form 4?
In the US, insider filings are centralized through EDGAR on the SEC website. In Europe, filings are published by each country's national regulator — BaFin in Germany, AMF in France, FCA in the UK, and so on. This means European data is fragmented across 20+ sources in different formats and languages. insider screener aggregates all of these into one searchable, normalized feed.
