Insider transaction timeline

Every reported transaction, positioned by trade date. Purchases sit above the axis, sales below; circle area is proportional to dollar value. No share-price line is drawn — this feed carries transaction prices only, and a price history inferred from them would imply market data the filings do not contain.

Not available for ARDX today: no reported open-market purchases in this window, so there is no insider cost basis to compute; no research case — nothing here has cleared the scoring threshold. Both appear on this page on their own if that changes.
