Could Anyone Make This Mt4 Indicator?

 

Hi folks,

I got one indicator from other platform, here is the program coded in that platform. Hope anyone can help to code it for MT4.

SMA21:MA(CLOSE,21);

GAO:=MA(REF(HIGH,1)/REF(CLOSE,2),27)*REF(CLOSE,1),COLORRED;

DI:=MA(REF(LOW,1)/REF(CLOSE,2),27)*REF(CLOSE,1),COLORGREEN;

Best regards,

Looks simple. I'm kind of busy these days, so I won't promise anything, but what does the indicator look like? Histogram? Colored line like a MA? Just a window of colors?
