Methodology

Formulas run in the browser and update from the values you enter. Values are bounded to prevent invalid or extreme calculations. Projections use constant rates for comparison and are never presented as guaranteed outcomes.

Provider responses are fetched on the server, validated against normalized schemas, cached for a limited period and shown with a source and timestamp. Delayed values are labelled delayed.

When a provider is unavailable, the interface reports that state. Development sample values live in a separate file, are visibly labelled and are disabled in production unless explicitly enabled.

Market summaries require a publication date and sources. Tamil financial content is published only after review; critical content is not automatically translated.
