Push result into array after each loop iteration-CodePudding

How can we get the result for i=2 to be pushed onto index 0 of the array and i=3 to be pushed onto index 1? at the moment I am getting the SUM of i=2 i=3 in index 0 and 1 as it shows on the image below:

myArray = array.new_float(0)

var counter = 0

for i = 2 to 3
    if close > ta.sma(close, i)
        counter  = 1
    array.push(myArray, counter)

if barstate.islast
    label.new(bar_index, 2, str.tostring(array.join(myArray, " - ")))
    label.new(bar_index, 1, "array size: "   str.tostring(array.size(myArray)))

Thank you in advance!

I'm not completely sure how to easily change your code to get what you want, but you can use the matrix to achieve this (as some kind of a dictionary workaround). Basically what you can do is lose the counter variable, and update the values directly to the matrix.

//@version=5
indicator("My script", overlay = true)

var myMatrix = matrix.new<float>(2, 2, 0)

for i = 2 to 3
    matrix.set(myMatrix, 0, i - 2, i)
    if close > ta.sma(close, i)
        matrix.set(myMatrix, 1, i - 2, matrix.get(myMatrix, 1, i - 2)   1)
  
if barstate.islast
    label.new(bar_index, 3, str.tostring(myMatrix))

EDIT:

If you really wish to do the same with array, you can use the same logic, but since pine scrip currently isn't supporting dictionaries, you'll need to use 2 separate arrays:

//@version=5
indicator("My script", overlay = true)

int start = 2
int end = 3

var my_array = array.new_float(end - start   1, 0)
loop_index_array = array.new_int(end - start   1, 0)

for i = start to end
    array.set(loop_index_array, i - start, i)
    if close > ta.sma(close, i)
        array.set(my_array, i - start, array.get(my_array, i - start)   1)   

if barstate.islast
    label.new(bar_index, 3, str.tostring(my_array))
    label.new(bar_index, 4, str.tostring(loop_index_array))
