pivothigh/pivotlow not working as expected

Question

Why is this code showing me wrong pivothighs it there are any? It is counting every second bar to the left and to the right not only one... If I change if to:

bar_index % 1 == 0, it is working right .

Here my code :

//@version=4
study("fckn test", overlay=true) 

if bar_index % 2 == 0
    ph = pivothigh(1,1)

    label.new(bar_index-1, low, tostring(ph))

Answer 1

Not too sure what you are trying to do. Perhaps this?

//@version=4
study("fckn test", overlay=true)
pivotLegs = 1
// Find pivot outside `if` block because needs to run on every bar.
ph = pivothigh(pivotLegs, pivotLegs)
// Detect a new pivot.
newPh = not na(ph)
// If a new pivot is found, save the bar index where it was found.
bh = newPh ? bar_index - pivotLegs : na
if bar_index % 2 == 0 and not na(ph)
    label.new(bh, high[pivotLegs], tostring(ph))
