Operating Data Sources

This tool is used for managing data sources. It allows adding/removing data sources, editing their settings, names and abbreviations, receiving data source information, their states and versions.

Adding Data Sources

Data sources are added automatically. The system auto-adds a data source as soon as the data feed's DLL is placed in the DataFeeds folder.

This data source appears in the data sources list but it is still inactive.

To activate the data source press Activate button (see Activating Data Sources section).

Activating Data Sources

Activation/deactivation is used to set the list of daily used data sources or for activating a newly added data source.

For full access the data source must be activated. If the data source is present in the list but marked in red, this data source must be activated.

To activate a Data Source:

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click Activate. The data source is now marked in green and the Settings, Name and Abbr parameters can now be edited.

Deactivating Data Sources

If a data source is not used, it can be deactivated. In this case, it will not be displayed in the list of available data sources when a symbol is added; if necessary, the data source can be reactivated later.

To deactivate a data source:

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click Deactivate. The data source is now marked in red and the Settings, Name and Abbr parameters cannot be edited.

Configuring Data Sources

Most data sources have unique parameters, e.g. server IP address, port, user name/login information, etc. See the [[LINK /102_Builtin_DataSources.html name=""; |Built-in Data Sources]] section for more detailed descriptions.

All the parameters for the integrated data sources are described there.

To edit a data source's settings:

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click the Settings button.

Cloning Data Sources

To use a data source with different sets of settings it must be cloned. Cloning creates a virtual copy of the data source with modified parameters.

For instance, to receive data from several DDE data vendors one needs to have several DDE templates.

In this case for every DDE data feed a unique data source must be created. If there are two DDE data feeds, Universal DDE and Universal DDE 2 must be created and a DDE template selected for each.

To clone a data source:

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click the Clone button.
3. Enter a Data Source Name (up to 3 characters).
4. Enter a Data Source Abbr (up to 3 characters).

Editing Data Sources

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click the Edit button.

Deleting Data Sources

1. On the Tools menu, click Data Sources, or click the Data Sources icon on the toolbar.
2. Select the data source using the keyboard or mouse and click the Delete button.
