How does Claude know which filters exist?

The connection publishes a full filter catalog and signal catalog that the assistant reads before building a screen. You describe the idea; it maps your words to the actual filters, so you never need to memorise filter names.

Is this better than the screener on the website?

Different, not better. The website screener is faster for iterating visually on a known strategy and for saving screens. The conversational version is better when you start from a fuzzy idea, want the results explained, or want to flow straight into deep research on a candidate.

Can it find intraday signals too?

Yes. Signal scanning covers things like volume spikes, 52-week breakouts, RSI reversals, and gap moves. Some signals update live during market hours while others are computed end-of-day, and results indicate their freshness.
