ScanExpert includes more than 80 built-in study formulas that can be called from scripts that you create as-is or combined to create new study formulas. The easiest way to access and use these study formulas is via the ScanExpert Wizard. The available study formulas are organized into groups in the Wizard Study Selection box. See the ScanExpert Wizard section for more information on how to select and configure study formulas.
For specific examples on how to call any of these formulas directly from scripts that you might write (as opposed to just using the Wizard to create the script for you, which is the recommended approach), just generate an example script in the Wizard and review the script in the Editor.
In almost all cases a study formula will be called as follows:
<StreamVariable> := StudyName(params,sources,interval);
where <StreamVariable> is a variable of type TEStream that you have declared in your script. Typically the study formula function is called only once to initialize the stream and thereafter the actual stream variable of type TEStream is used to access the data values. Again, when in doubt the best course of action is to generate a script using the Wizard and then examine the resulting script in the Editor.

Note: Study formulas are being added to the ScanExpert program all the time so it is possible that more formulas will be available in the Wizard than are referenced in this section.
