Adding an Indicator

To add an indicator (or set of indicators) to a new dataset, the first step is to select the dataset that you wish to use as the base data from which the indicators will be derived. Select the dataset in the data drop down box, enter a name for the new derived dataset in the name textbox, then click the add button. This will add a new tab to the indicator app.

Next, you will select a field or fields from which to derive a set of indicators. To do this, select a field name in the Field drop down box. Then click the add link underlneath the Fields listbox. This will add the field to the listbox. If your indicators are calculated off of a single field in the source dataset, you are done adding fields, otherwise, you will want to continue adding fields until you have selected all the fields you need.

When you are finished adding fields, choose the type of indicator you want to add. Indicators are grouped into categories called types. By selecting a type in the type drop down, the indicators that match that type will be dispalyed in the drowdown below the type dropdown. Select the name of the indicator you wish to add. Then enter a name for the indicator in the new dataset and enter that in the indicator name textbox.

Next click the add button. If there are any parameters you need to specify, you will be presented with a dialog window where you enter in the parameters. For instance, if you choose a moving average indicator, you may be presented with a dialog asking you the size of the moving average. After entering in the required parameters, a script will be generated that generates the requested dataset and displayed in the center window. You can continue to add new indicators to the dataset which will update the generated script.

Once a script has been generated, you can run the script by clicking the run button. This will run the script and generate the dataset. Alternatively, you can add the script to your workspace by clicking the add script link. This will add the script so that it can be saved with your workspace and retrieved.
