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 MACD 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.
