Support Resistance - Dynamic v2 — Indicator by LonesomeTheBlue

Hello Traders! After the addition of "Arrays" to the Pine, I developed new and improved version of Support Resistance - Dynamic script as version 2. In this script Arrays were used. This can be used as Support Resistance tool, also it will be an example for the people who want to learn Array...

i've tried asking in other forums. the consensus is that Array code cannot be converted into thinkscript. your best best is auto fib lines.

Sharing an advice from OpenAI chat:
----------------------------------------------

In ThinkScript, arrays are declared using the "var" keyword and the "array" data type. The syntax is as follows:

Copy code
var <array_name> = array.new_<data_type>(<initial_size>);

For example, to declare an array of floats in ThinkScript, you would use the following syntax:

Copy code
var myArray = array.new_float(0);

This will create an empty array called "myArray" that can store float values.

If you want to initialize the array with a certain set of values, you can use the array.set function to set them.

Copy code
var myArray = array.set(1, 2, 3);

You can also use the array.new_float function with initial values as parameter

Copy code
var myArray = array.new_float(1, 2, 3);

You can also use the array.unshift function to add new elements to the beginning of the array, and the array.pop function to remove the last element of the array.

In your script, the following line array.unshift(pivotvals, ph ? ph : pl); is used to add new element to the beginning of the array.

Copy code
array.unshift(pivotvals, ph ? ph : pl);

And the following line array.pop(pivotvals); is used to remove the last element from the array.

Copy code
array.pop(pivotvals);

You can access an array element by using the array.get function, like this:

Copy code
float cpp = array.get(pivotvals, y);

You can also use array.size function to know the size of the array.

Copy code
if array.size(pivotvals) > maxnumpp
