I don't get all this bashing on Armstrong. Before finding out about Armstrong, I was Austrian school of economy. Still though not feeling comfortable, because some of the things were unfolding opposite of what Austrians (or any other economic school for that matter) was preaching. And that's how I found Armstrong, this was the only guy who got the things right, regarding the aftermath of the last GFC. After I found out about him, went back on his blog, and check his previous writings. Following him for few years now, and I don't think there is anyone else close to him, who can explain economy subject better (I give Taleb a credit though). All these economy schools now appear to be Mickey Mouse comparing to Armstrong teachings.
Now, about the trading. Would I use Armstrong for daily trading, more likely that not, I would not, primarily, but rely on other trading tools. His medium, long term predictions, hell yes. And definitely would like to have access to his reversal numbers, on a bigger time scale (weekly and up).
He mentioned few times that he is writing a book. I hope he will finish it and publish it, can't wait for it.
