Conversion of an ELA formula to Metastock

[Joe Acevedo <cn001532@xxxxxxxxx>]

Could anyone help me out with converting an Easy
Language Double Stochastic Indicator to Metastock?
Below is the ELA formula:



Function:

_DStoc: Double Stochastic}

Inputs: DStLen(NumericSimple);

Vars:  
Num(0),Denom(0),Ratio(0),PctK(0),DNum(0),DDenom(0),
        DRatio(0),DPctK(0);

{Stoc}
Num=C-_Lst(L,DStLen);
Denom=_Hst(H,DStLen)-_Lst(L,DStLen);
Ratio=IFF(Denom>0,(Num/Denom)*100,Ratio[1]);
PctK=IFF(CurrentBar=1,Ratio,PctK[1]+(.5*(Ratio-PctK[1])));

{DStoc}
DNum=PctK-_Lst(PctK,DStLen);
DDenom=_Hst(PctK,DStLen)-_Lst(PctK,DStLen);
DRatio=IFF(DDenom>0,(DNum/DDenom)*100,DRatio[1]);
DPctK=IFF(CurrentBar=1,DRatio,DPctK[1]+(.5*(DRatio-DPctK[1])));

_DStoc=DPctK;


{_Hst: Calculates Highest Values}

Inputs: Price(NumericSeries),Length(NumericSimple);

Vars:   X(0),Hi(-999999);

Hi=-999999;
For X=0 to Length-1 begin
  If Price[X]>Hi then Hi=Price[X];
End;

_Hst=Hi;

{_Lst: Calculates Lowest Values}

Inputs: Price(NumericSeries),Length(NumericSimple);

Vars:   X(0),Lo(999999);

Lo=999999;
For X=0 to Length-1 begin
  If Price[X]<Lo then Lo=Price[X];
End;

_Lst=Lo;
