LOL. I didn't click the link but if ew. com really published this, I am highly disappointed...
I learned from the most famous german Trader Andre Tiedje, 25year EW Pro, you can buy his book at amazon. He says R.R. Prechter is wrong on so many levels and I agree.

It makes no sense to allow anything that R. N. Elliott did not allow when he developed the ruleset.
By the way, he publically traded 100k to 29 Million in the last 13 years, all trades published with video and picture proof in his trading room.
