Nen, Poruchik at all are generating dozens of new harmonic patterns. I am puzzled -- what criteria of their validity they use? The new patterns must at least satisfy the condition of statistical significance, like 70/30 probability of realization, right? I've never seen they discuss backtesting of the new patterns, only like '...XYZ proposed new wonderful pattern...'
Are you limiting yourself by Carney/Pesavento limited set of patterns, or extended Nen/Porichik style?
Also, I am having trouble with Carney definition of XABCD patterns. What I mean, if you calculate DA versus XA through his relations XA -> AB -> BC -> CD -> DA, you'll come to contradictory numbers. Pesavento doesn't exploit intermediate relations as Carney does.
