One could argue that you don't need a second MA because you already have colour change on slope change (which gives earlier signals than a second MA; albeit sometimes less trustworthy) - but then everyone trades differently.
Many people don't want to confront this fact (because they glorify Mladen for all the extraordinary work he has done):
I think this one has better signals than Mladen's indies normally have but still:
let's assume you know in which direction you want to trade in each instance (by using e. g. higher TF for directional bias):
Does this indicator give better signals than the MT4 built-in MA?
My advice: compare Mladen's indicators to one by MrTools (for example: Jurik Volty bands).
I think you will find that - for now - it produces better signals most of the time.
