Sorry, misunderstood the initial question.
I did use to work with the Experts and remember finding the Chande Checker or something or other like that, was quite good (American quite, not English quite).
However it took significant rework to get it to perform reliably across all market conditions and needed an evaluation of the change of bias from the underlying expert itself and a couple of things I forget. I think to do with the proximity to the various ranges it was specifying and how they themselves were changing over the progression of the bars.
The amount of effort that went into the recoding was never justified by the risible 94.8% accuracy attained though. So I binned it.
