Support Resistance Weekly Bars - Repost (website issue)

This indicator plots horizontal lines for the high and low of each of the last x weeks (configurable from 1 to 20). Increasing this number beyond 20 is not possible due to some technical Pine limitations. I am also publishing a daily and monthly version...add them all to the same chart!

Reposting because something broke, and the first version is no longer available in my list of scripts to update (needed to fix a bug).
