Right here goes:
I've coded it up as per VT's formula, when viewing TS alongside the VT version it's acts very similar, but it's not exact due to the slight variation in code between the ADX function in TS and the ADX function in VT.
Anyway, I think it's close enough, but if anyone wants to try and modify it further then send me a PM ( rather than clutter up this thread ) and I'll explain the discrepancy.
NOTE: When installing it onto your chart you'll have to:
A): Change the colour of your background to grey.
or B): Change the colour of the "VarMa" plot to a different colour than black.
