researchbook · offline read-only 60s poll

Universes.

Named symbol sets registered with the researchbook HTTP service — the same registry the /backtest selector reads from. Built-in entries are hand-curated static lists; parquet-backed entries are bitemporal — member counts reflect today's slice via Universe.at(date.today()).

For the strategies that run against these universes, see /strategies. For the morning briefing across all services, see /desk.

live polling needs JS — the skeleton stays static without it. read the description above; turn JS on to see the actual universes.

researchbook offline

This page needs the researchbook HTTP service.

The build environment didn't set PUBLIC_RESEARCHBOOK_URL, so there's no service to read from. The universe + backtest architecture is documented on the system page.
