@dave.seremek, Hi, good question, love this guys scripts and have learned so much from them. Looks like that color change occurs when the "HL Avg" (avg series) crosses the mean (the horizontal purple) and you can set an alert on the chart crosses or crosses under or crosses over. Should make a solid signal when combined with something for momentum. At least for my trade style I want movement as well as direction. Hope this helps and thanks to Ricardo for another great script!
