Answer 1

This will give you what you're looking for.

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

var int decimals = int(log10(1/syminfo.mintick))

if barstate.islast
    label.new(bar_index, high, tostring(decimals))

Improved version.

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

var int decimals = str.length(tostring(syminfo.mintick))-2

if barstate.islast
    label.new(bar_index, high, tostring(decimals))
