Hist_StepMA_Stoch

Hi Guys and sorry for the intrusion.

I have been asked a couple of times about this indicator...
Hist_StepMA_Stoch... and if it can be written in VT Trader language.

Problem;
I have 2 I guess.
1) I can't translate MT3 or 4
2) I'm not sure what the indicator does or how it is calculated.

Question;
If anyone is familiar with this indicator, can they please explain, in Plain English, how it is calculated.
