Global trading calendar

The “Global trading calendar” and the trading calendar per stock exchanges are used to check the completeness of historical price data.

This defines the upper set of trading days for all stock exchanges. In principle, no trading takes place on Saturdays and Sundays. In most cases, only January 1 and December 25 are entered as global non-trading days.

Edit global trading calendar

Only the administrator has the necessary user rights to make changes to this trading calendar.

A year selector dropdown lets you switch between years. Previous/next year buttons are available for quick navigation. The year range spans from the oldest to the youngest trading calendar day in the database. The year cannot be changed while unsaved changes exist.

Marking days

Clicking on a weekday toggles it between a trading day (lime green) and a non-trading day. Newly changed days appear in yellow until they are saved. Saturdays and Sundays are always disabled and cannot be clicked.

Mark working days of full year

This function is available via the context menu (right-click). It marks all weekdays (Monday through Friday) of the selected year as trading days in one operation. Only days that are not yet marked will be added. This is useful when initializing a new year.

Underline toggle

The Show menu offers an option to toggle underlines on marked dates for better visibility.

Saving

The Save button is only available to administrators. It remains disabled until at least one change has been made. After saving, the new changes (yellow) become confirmed trading days (lime green).
