Redoing the comments on the script to follow House Rules.
The main idea behind this script is for the indicator to automatically draw lines between BB% convergences and divergences in an effort to see future divergent lines that cross. The idea is to correctly interpret what the white/aqua lines do to price/trend when they cross. Also what it does to price/trend when just white/white or aqua/aqua lines cross as well.
Previous historical divergences between those sets of lines in question have related to major pivots in price and trend.
