Data quality
Today's brief, the detectors and the open issues.

The detectors

CheckFinds
Stale priceA security whose last close is older than expected.
Price jumpA close that moved more than 20% (flagged, not refused).
Missing classificationNo sector or country.
No identifier / Duplicate identifierMissing or shared ISIN, CUSIP, SEDOL or FIGI.
No average volumeMissing average daily volume (needed by liquidity rules and the simulator).
Negative cashAn account below zero cash.
Inactive security heldA position in a security that is no longer active.
Stale FX rateAn FX rate older than expected.
Unusual feed volumeA feed file much larger or smaller than usual.

Run the checks now runs them (they also run on schedule and in the start-of-day chain). An issue stays open while a check sees it and resolves itself when the data is fixed.

The AI's part

The AI writes today's brief and the story of a price jump, and can suggest a sector and country for securities that lack them: the suggestions are staged as a batch you review and apply (or discard). It never changes an issue.

  • The loading center Load reference data, holdings and market data from a file or a folder: column mapping, deterministic validation, a diff before anything changes, apply and undo.
  • The start of day The deterministic chain that applies the morning's data in order, from calendars to pre-open compliance; until it completes every page says so.
  • Feeds and start of day Feeds are data sets that arrive on a schedule (drop box, HTTPS push or pull); each file becomes a batch, and the start-of-day chain applies them in order.
  • Securities and prices The security master, simulated or uploaded end-of-day prices, and each security's page.
