Declares one or more names as inputs; specifies the default value and defines the input type for each input. Inputs can be numerical, string, or true/false. Once declared, the value of the input cannot be modified by the study's code.
Usage
Input: InputName1(DefaultValue1), InputName2(DefaultValue2), etc.
Parameters
- InputName - an expression specifying the input name. The name can consist of letters, underscore characters, numbers, and periods. The name cannot begin with a number or a period and is not case-sensitive.
- DefaultValue - an expression specifying the default value and defining the input type. The expression can be numerical, string, or true/false; the type of the expression defines the input type.
Notes
- The reserved word Input is equivalent to Inputs.
Example
Declare Length as a numerical input with the default value of 20:
Input: Length(20);
Declare Price as a numerical input with the default value equal to the value of Close function, and Name as a character string input with the default value of "Last Close":
Input: Price(Close), Name("Last Close");
Declare Draw_Line as a true/false input with the default value of True:
Input: Draw_Line(True);
