S&P 500 Elliott Wave Technical Analysis – 29th May, 2014 by Lara | May 30, 2014 | Uncategorized | 2 comments 2 Comments Thomas Piccolo on May 30, 2014 at 2:48 am Lara You have stated several times that ending diagonals must be single zigzags. I have a book writing by Wayne Gorman and Jeffery Kennedy called Visual guide to Elliott Wave Trading. Both of these men work for EWI. They stat under ending diagonals that subwaves 1,2,3,4,and five always take corrective-wave form, specifically either a single or multiple zigzag. I would like to know if you have any more information about this subject. Elliott Wave Stock Market on May 31, 2014 at 6:21 am These are the rules I’m interpreting: From “Elliott Wave Principle” by Frost and Prechter, page 87: “waves 1, 2, 3, 4 and 5 of an ending diagonal and waves 2 and 4 of a leading diagonal always subdivide into zigzags and page 88: “waves 1, 3 and 5 of a leading diagonal usually subdivide into zigzags but sometimes appear to be impulses”. I early on interpreted that to mean that in an ending diagonal all the subwaves must be single zigzags. Because no other structure was named. Over the years I have not seen an ending diagonal with subwaves any structure other than single zigzags. But then, if that’s what you expect to see, then that’s how you’re more likely to see it. I am aware I could be subjective.
