Data sources and time windows

Each daily article lists its instruments, original source links, trading sessions or measurement windows, and data quality. Use that edition's records to check its claims.

How to compare changes

Stocks and crypto assets trade on different schedules. Changes from different windows are not treated as comparable returns over a single period. Missing values stay missing; substitutions and limits belong in the article's coverage note or data table.

Sources and interpretation

News and social discussion are cited only when their original links are available. Opinions and possible links are presented as interpretations to test. Research notes return to company announcements, financial statements, regulatory material or original studies before developing an argument.
