The Curve Formula Editor displays the formula or expression associated with the study curve selected in the Curves for section. It is empty when a new curve name is initially selected.
The editor consists of the editor area, where the selected study curve's formula is shown, and several Editor buttons. The expressions can be modified directly in the Editor, or they can be modified using the Editor buttons.
1. If the Curves for: [study name] information is not already displayed, left click the Show Curves button.
2. Click the study name in the Study Names list.
3. Click the New button in the Curves for section.
4. Enter a name for the new study curve.
5. Enter the desired Curve Formula directly in the Formula for Curve section.
You can also click the Toolbox button to display the Formula Toolbox window and use the Toolbox to define the curve formula.
Custom Studies use scales that are unique to that study. However, an operator can be added to a Custom Study curve formula to force the Custom Study to share the scale of the underlying chart.
Currently, the ShareScale operator is added in the Custom Study curve formula. The ShareScale operator has two parameters separated by a comma. The first parameter is the Custom Study curve formula itself. The second parameter identifies whether the Custom Study curve shares a scale.
Example: ShareScale(custom study formula, @) forces the curve to share the scale with the bar scale, identified by @.
Study Outputs cannot be changed within the Curve Editor. However, you can modify them by selecting the Study Output and then by selecting the Setup button to display the parameters.
When the cursor is placed on a Study Output or one of its parameters, the entire Study Output expression is selected. All or none of the Study Output expression must be removed at one time. Individual parts of a Study Output expression cannot be removed.
The clipboard can be used to cut and paste text into the Curve Editor.
