Read the observation date
A monthly average and a daily reference do not describe the same moment. Keep the frequency and date beside the number.
Turn a sourced chart, calculation or lesson into something another person can open, change or publish.
A shared result should lead somewhere useful. Open the markets hub for the original price, use the data workbench for aligned history, or check the source methodology.
When you share a number, preserve its observation date, unit and source. The latest snapshot and embeddable widgets are designed to carry those labels with them.
