Hello,
I can write you the script for the indicator. Actually I have already done that.
Here it is:
//@version=3
study("ROC Arrows", overlay=true)
i = input(14, minval=2)
r = roc(close,i)
r1 = roc(close[1],i)
val = r > 0 ? (r1 < 0 ? r : 0) : (r1 > 0 ? r : 0)
plotarrow(val, minheight=20, maxheight=20)
The script looks short, but there is a work behind it. I am posting the script here, because I believe in your honesty that you will hire and pay me.
I can also do some adjustments to the script.
Best regards
George K
