Is it possible to return the bar_index of a PivotHigh in Pine Script 5?

Question

I'd like to set the index of bar_index[] based on ta.pivothigh in a dynamic way.

// PivotHigh Check
leftBars= input(4)
rightBars = input(4)
ph = ta.pivothigh(leftBars, rightBars)
plot(ph, style=plot.style_circles, linewidth=3, color=#ffffff, offset=-rightBars)

// Draw the line
upperLine = line.new(bar_index[10], high[10], bar_index[20], high[20], color=#ffffff, width = 2)

As you can see the numbers 10 and 20 aren't written in a dyinamic way, because I wrote the index of bar_index and high. Is it possible to return the value of each circles made by ta.pivothigh in order to fill the index automatically?

When your pivot is drawn, you are 'rigthBars' away from it. So the index of your pivot is bar_index-rigthBars.

//@version=5
indicator("test", overlay = true)
var IndexNewPivot = 0
var IndexOldPivot = 0
// PivotHigh Check
leftBars= input(4)
rightBars = input(4)
ph = ta.pivothigh(leftBars, rightBars)
plot(ph, style=plot.style_circles, linewidth=3, color=color.purple, offset=-rightBars)

if ph > 0
    // Draw the line
    IndexNewPivot := bar_index - rightBars
    upperLine = line.new(IndexOldPivot, high[bar_index - IndexOldPivot], IndexNewPivot, high[bar_index - IndexNewPivot], color=color.blue, width = 2)
    IndexOldPivot := IndexNewPivot

The result :
