Sorry, I´m not here to discuss my performance or initiate a flame war. I´m not here either to defend Martin Armstrong or express my opinion about the person.

I´m here to discuss some of his work/models, which are valid and COULD give you a edge on the markets. Some of his models, are general math derivations and technical analysis stuff, I´m not interested in discuss it. I see value in discussion only their proprietary models.

GMW for me is trash, I trade numbers, not words/opinion or descriptions of what happening in the market;

ARRAY´s is a very complex way of representing cycles, I look at them before my final trading decision but don´t waste more than 10-20 seconds looking at it.

Reversals are the most valuable part of his work (it´s just my opinion)

ECM models and Pii cycles frequency are valuable at academic level, I see as a big improvement over most of economic models/theory on cycles but think have limited use as trading/investing tool.
