I totally agree with you Mr. Pip.
Although this indicator looks good to the untrained eye.
It is a very complex indicator, that may produce many false positives.
Like any indicator one has to thoroughly learn its mechanics, tweak its settings... in order to incorporate it into ones arsenal.
Event then we are still at the mercy of the markets; if we do not have (or trust) our edge.
I believe mastery of the markets is possible but it takes hard work and discipline. The problem is not the markets it's us. We over complicate simple processes and that is within us to fix.
If you fail to plan, you plan to fail.
