Constant

Constant returns a constant value.

Chart Example

Implementation and Usage

To implement constant in a strategy use the following constructors:

Constant – sets the default value equal to 7 as a constant value.

Constant(Double) – creates constant with given fixed value.

This indicator supports simple prototype of method Add():

Add(Double)

Add(Double, DateTime)

But the value of this indicator is not updated so there is no reason to use method Add() as it does not change the initial value. Use Result property to get the constant value.
