Hi triplepack
The chart on page 54 is the nearest - it's not the same, but there are similarities. And RM is an awful lot simpler than the 9 point square, on which the chart on page 54 is based.
I've got a lot on my plate right now, so I'll try and find the time to read chapter 4 over the next few days and see if there's anything else which is similar to RM. I bought Constance's book yonks ago and never got round to reading it, although I did have a brief look at a few charts!
I took a quick look at the intro to BM and the author says that he has tried Gann, Elliott and much more, and did the Wolfe Wave course, and while he derived some valuable information from each, "in the real scheme of things they all led to disappointments."
It's not Delta. The whole market is based on cycles, so everything used in trading can be traced back to cycles at some point.
It's a simple pattern which appears on a bar chart which indicates a reversal point. You need to use discretion to and practice to know which are the correct points to use, but that just takes time and dedication.
