Stock exchange

The instruments are traded on the stock exchanges. In GT, these are important for the following reasons:

  • The trading calendar of a stock exchange can be used to evaluate the completeness of historical price data.
  • The assignment of the stock exchange to an instrument determines whether there is any publicly accessible price data for this instrument.
  • In a future GT version, the update of historical price data will be staggered over the periods of the closed stock exchanges. The country and time zone can no longer be changed for an existing stock exchange; this is intended to prevent the total rewriting of a stock exchange.

Create and edit asset class

A stock exchange is created, edited and deleted in the main area in the stock exchange view. You can access this view in the navigation area on the static “stock exchanges” element.

  • Create a stock exchanges via the context menu.
  • Edit a stock exchanges via the context menu when a stock exchanges is selected.
  • Delete a stock exchange via the context menu with the stock exchange selected.

Properties and table columns

  • MIC: When the MIC (Market Identifier Code) is selected, the name, country and website are automatically assigned. For the main stock exchanges, the time zone is also set. The MIC can be used in certain price data connectors.
  • Country: The country is controlled by the selection of the MIC and cannot be changed.
  • Name: The name of the stock exchange is automatically specified in lower case by the selection of the MIC. This should be corrected accordingly. This may change over time due to mergers of stock exchanges.
  • Secondary market: Some securities are not traded on the secondary market, but there is price data that can be downloaded from a provider. However, most securities are traded on the secondary market.
  • No course data: If there is no price data, this checkbox should be marked. This activates the option to enter “Historical prices for period” when entering the instrument.
  • Opening time, closing time and time zone: In a future GT version, the update of historical price data will be staggered in the time periods of the closed stock exchanges. These properties determine the period in which the update can take place.

Additional properties when editing

  • Main exchanges only: The selection of the MIC is restricted or extended to the main exchanges or all known MICs according to this selection box. It is partly arbitrary what is defined as a main exchange in GT, we hope that nobody feels negatively affected by this selection.

Index for trading calendar

The trading calendar can be updated automatically via an index traded on this stock exchange. Of course, this can only be set with the second processing of the stock exchange. This means:

  1. Enter the stock exchange.
  2. Optionally create an asset class for the corresponding country and index.
  3. Create an instrument for this index.
  4. Add the stock exchange with the created index in the “Index for trading calendar” input field.

Trading calendar

The trading calendar of a stock exchange is a prerequisite for the completeness check of the historical price data. The “automated marking” for closed days via the index is only applied after the most recent day marked by the user. This means that the system never marks a day that is older than the most recent blue marker.

  • Open days: Days marked in green are defined from the global trading calendar.
  • Closed days: Days marked in red were originally created by the index for trading calendars. Days marked in blue were created by the user. The copy functions do not change these characteristics.

Functions

There are two copy functions for copying an entire trading calendar or an annual calendar to the selected annual calendar. Existing calendars are overwritten.
