Studies are PowerLanguage scripts, expressing trading rules in a systematic and logical way that can be executed by a computer. Scripts consist of at least one, but usually more, statements. Each statement is a complete instruction.
To learn more, see [[<span style="color: red;">'''LINK'''</span>/04_PL/41-0006_Elements.html name=""; Language_Elements|PowerLanguage Elements]]
PowerLanguage scripts can be easily created and edited by using the PowerLanguage Editor. PowerLanguage Editor includes many advanced text editing features, built-in PowerLanguage keyword reference, and a keyword hint feature.
Before a study can be applied to a chart, the study's script must be [[<span style="color: red;">'''LINK'''</span>/03_PLE/31-0103_WorkingStudies.html name="4"; Editing_Study_Scripts#Compiling Scripts|compiled]].
The code is compiled directly in the PowerLanguage editor.
The script of a study can be [[<span style="color: red;">'''LINK'''</span>/03_PLE/31-0103_WorkingStudies.html name="5"; Editing_Study_Scripts#Protecting Studies|password protected]]; script of a protected study can not be viewed without the password.
