Koyfin Screener: Coverage, Access & Export Checklist

Documented research workflow

Stock and ETF research within a broader financial-data workspace; screening scope expands by package.

Access and package boundaries

The current provider guide says Free includes stock screening, while ETF data and ETF screening begin on Plus. Plus is listed at 39 USD/month when billed annually.

What to verify

Do not describe Koyfin Free as a free ETF screener. A monthly equivalent billed annually is not a cancellable monthly price. Historical estimates and financial definitions require explicit period selection.

A practical acceptance task

Check the same screen against Free and Plus entitlements. Verify ETF availability and save the filter/period definitions alongside an exported or recorded result.

Keep the research reproducible

Record the universe, active filters, financial period, quote timing and source version. Re-run a small example before replacing an existing research process. A result count can change as data updates or the available universe changes.

Separate selection from performance

A screen narrows a source dataset. It does not establish a causal explanation, a diversified allocation or a historical return. Inspect filings, fund documents, liquidity and the suitability of the underlying research question before using the output.
