Screeners
Saved rules that pick stocks from the data above, run on demand or on a schedule.
Sources
Every dataset on these pages: prices, broker flow, running trades, ownership and filings. A screener reads only data that existed at the moment it ran.
Coverage
6 official screeners are public and 3 are experimental. Official screeners ran 156 times on 23 trading days in the last 30 days.
Update frequency
On demand, or on each screener's own schedule.
What an agent can do alone
With an account, an agent can list, run and build screeners. Without one, it can read the record of the official screeners' calls.
Known gaps
A screener using running trades inherits their sampling: its results on the busiest stocks are less reliable than on the rest.
When it fails
Data-health warnings, such as stale or missing source data, are attached to a run's results rather than hidden.
