Pine Script: print not NaN values of a series

August 15, 2022

The following script creates a label for each element of the series. How can one create a label only on candles with corresponding not NaN values?

//@version=5
indicator('Print text values', overlay=true)
length = input(2)
up1 = ta.pivothigh(high, length, length)

l = label.new(bar_index-length, high, str.tostring(up1))

>Solution :

There is actually a na() function to test if the value is na.

So, you can do the following.

//@version=5
indicator('Print text values', overlay=true)
length = input(2)
up1 = ta.pivothigh(high, length, length)

if not na(up1)
    l = label.new(bar_index-length, high, str.tostring(up1))
