Discovery
Screeners are good at finding what matches a filter.
A screener can help a trader identify symbols or setups that meet visible criteria. That is useful, but it usually leaves the deeper research burden scattered across charts, notes, tests, and broker tools.
- Use screeners to narrow the market, not to finish the decision.
- Treat a matched filter as the start of research.
- Keep the next question focused on evidence and tradeoffs.
