Trend Higher highs and Lower High

I encourage folks in the Q&A forum not to use those shared links. They can be revoked or can even expire. So please post the full code in the future.

Here is the code you linked to that has been converted to work as a scan. Screenshot below shows the results of the scan for the "up arrow" signal.

# scan signals
plot ArrowUP = x == highestAll(upBar) ;
#plot ArrowDN = x == highestAll(dnBar);
