The best stock screeners share three traits — most screeners have one
A screener is useful only if (1) it covers your markets, (2) the logic behind each hit is inspectable, and (3) the free tier is real. Here's how the landscape lines up against those three.
Compare on these axes
| Screener | Markets | Signal logic | Free depth |
|---|---|---|---|
| Balance Labs (STM) | US · HK · A-share · KR · India | Documented STM timing + 10-yr backtest | Preview + 30 AI credits |
| Traditional screeners (FINVIZ-class) | US-heavy | Filters only, no timing | Limited |
| Broker-built screeners | Varies | Filters | Varies |
| AI assistants (FinChat-class) | Global | Q&A, not a repeatable screen | Trial |
Why we built signals instead of filters
Filters output lists. A signal outputs a state with history — for every one of 753 tickers you can see the current stance, its age, and the backtested behavior of that stance. That's the difference between a list and a decision input.
