Wow - pretty good signal.
It would be worth producing a button-version for this one (maybe call it: HMA Master 21 Next MTF).
Maybe - if possible - add an input for horizontal line-length as these lines not only indicate the turnaround of the indie (and upwards of H4 disappear altogether) but - if you zoom out - often give an excellent idea of later support & resistance, i. e. entry & exit.
