SYNTAX

Code: Select all

<var_name> := <new_value>

EXAMPLE

Code: Select all

//@version=5
indicator("My script")

myVar = 10

if close > open
    // Modifies the existing global scope `myVar` variable by changing its value from 10 to 20.
    myVar := 20
    // Creates a new `myVar` variable local to the `if` condition and unreachable from the global scope.
    // Does not affect the `myVar` declared in global scope.
    myVar = 30

plot(myVar)

Does this help us at all?
