while studying to build systems using AFL, I've come across this forum.
http://www.inditraders.com/amibroker/19 ... terns.html
it looks like an automated detection of harmonic patterns. can you guys try it and see how it goes? I haven't updated my AB yet
kailangan ko na siya iupdate. sseriosohin ko na pag systems trading 
I'll check the attached AFL later paguwi ko.

/* HARMONIC PATTERN DETECTION
Automatic Detection of Harmonic Patterns - Gartley, Bat, Butterfly and Crab.
Zig Zag is not used in this AFL. It is based on fractals
