This guy (also known as TraderJoe)

seems to me one of the best Elliott Wave experts.
Have a look at his analyses in the Blog and his Youtube videos here https://www.youtube.com/user/ElliottTrader
Also his "The Eight-Fold Path Method for Counting an Impulse"
http://studyofcycles.blogspot.com/2016/01/the-eight-fold-path.html
is very interesting.
