US insider trades

Every SEC Form 3, 4 and 5 since 2006, updated daily: who bought or sold, at what price, in what role — with open-market purchases separated from grants and option exercises.

16 years, one format

ASIC changed its file format in 2022 and its percentage scaling more than once. Short % here is recomputed from share counts, every day, for every security.

Built for AI tools

An MCP endpoint lets an assistant answer "what's the most shorted lithium stock and how has that changed this month?" directly.

Honest dates

Each row is labelled with its position date. ASIC publishes about four trading days later; we never pretend it's today's data.
