hi pacios,
i believe there is a strong filtering for the arrows which is MA step level..
here i attached mladen 2 indicator .. 1 is latest which is in main chart ex file only i have and 2. histogram which is similar .. not sure.
this indicator can filter most of the bad signal see snap

rule...

MA get arrow @ close price/ time frame.. and the 1st DYMI arrow painted @ cose price only to painted
setting input : 1st or 2nd DYMI - TRUE/FALSE
