Insider trading, in numbers

• A declaration is one manager-transaction disclosure published by a regulator (MAR Article 19, SEC Section 16 Form 4, and equivalents), deduplicated per filing id.
• Months are calendar months (UTC) of the regulator publication date; only complete months are published.
• Amounts are EUR-normalised at ingestion using the FX rate of the publication date.
• Buy and sell classification uses an open multi-language matcher on the disclosed transaction nature; feeds whose labels are not yet recognised count in totals but not in buys or sells, and a filing matching both directions counts in both.
• The largest-purchases table keeps reported amounts only: estimated amounts and implausible feed artefacts are excluded.
• Compute path and definitions live in the open scoring and stats layer described on the methodology page; independent audits are published in the method-review archive.
