Convert AFL to MQL4

I Have a simple AFL Code which I would want to be converted to MQL4. This is just a few lines of code and this needs to be done ASAP

Please let me know how soon can this be done.

 This is the Code

_SECTION_BEGIN("power");

Periods = Param(" ma Periods", 14, 1, 100 );

range = Param("ATR range", 10, 1, 50 );

multiplyer = Param("multiplyer", 2, 1, 10, 0.1);

uptrend= MA((H+L)/2,Periods) + multiplyer*ATR(range);

downtrend= MA((H+L)/2,Periods) - multiplyer*ATR(range);

Bbuy=  ExRem( H> uptrend ,  L< downtrend )      ;

sSell= ExRem(  L< downtrend , H> uptrend )      ; 

Thanks
