Half-Trend Indicator MQL4 > MQL5

Hi all,

I would like to have the attached mql4 half-trend indicator transformed to a mql5 class and an indictor using the class with the following interface.

class cHalfTrend

{

public:

    cHalfTrend(void){};

    ~cHalfTrend(void);

void Init(ENUM_TIMEFRAMES pChartPeriod, int pMALowPeriod, int pMAHighPeriod, int pATRPeriod, ENUM_MA_METHOD pSmoothingMethod, ENUM_APPLIED_PRICE pAppliedPrice);

void Load(int pLength = 1);  // Loads pLenght values to a buffer

double GetValue(int pOffset = 0);   // Returns the value with an optional offset from the latest period - before Load must be called

      ENUM_TREND cHalfTrend::GetTrend(int pOffset = 0);

}; 

The class I want, so I can use the indicator form an EA.

Regards

Michael
