This is a bit unusual for an Over My Shoulder posting. It is a short briefing paper that “Doc” Ahrens wrote on the intersection between complexity theory and technical analysis. I will confess to being fascinated by complexity theory and its intersection with economics, but complexity and chaos math formulas just go straight over my head. So I try to get the gist and direction of it rather than diving into the math. But Doc has done a good job of giving us a bigger picture. About three pages with lots of footnotes – I found this to be useful.
