As in functions, such variables are also local to the loops scope. to achieve the fastest-loading charts, and to share our common resources most equitably), We can use Pines ability to have functions return a tuple to gain access to the variable: Contrary to global scope variables, array elements of globally defined arrays can be modified from within functions. In Pine Script, the form-type of such colors is called const color (see the Type system page). If both your indicators used fixed ranges, you can shift the values of one of them so they do not overlap. We cant run plotchar() inside an if statement. is useful because it has some line styles unavailable with plot(), can be a literal, a variable, an expression or a function call.
