Hi,

May somebodey help me to convert a code from MT4 to Prorealtime?? Im searching for the Bill Williams ADX indikator in the same style as MT4. Can sombeodey tell where to find it or programing it?

Her is the code:

#property indicator_separate_window
#property indicator_buffers 3
#property indicator_color1 LightSeaGreen
#property indicator_color2 YellowGreen
#property indicator_color3 Wheat
//—- input parameters
extern int ADXPeriod=14;
//—- buffers
double ADXBuffer[];
double PlusDiBuffer[];
double MinusDiBuffer[];
double PlusSdiBuffer[];
double MinusSdiBuffer[];
double TempBuffer[];
//+——————————————————————+
//| Custom indicator initialization function |
//+——————————————————————+
int init()
{
//—- 3 additional buffers are used for counting.
IndicatorBuffers(6);
//—- indicator buffers
SetIndexBuffer(0,ADXBuffer);
SetIndexBuffer(1,PlusDiBuffer);
SetIndexBuffer(2,MinusDiBuffer);
SetIndexBuffer(3,PlusSdiBuffer);
SetIndexBuffer(4,MinusSdiBuffer);
SetIndexBuffer(5,TempBuffer);
//—- name for DataWindow and indicator subwindow label
IndicatorShortName(“ADX(“+ADXPeriod+”)”);
SetIndexLabel(0,”ADX”);
SetIndexLabel(1,”+DI”);
SetIndexLabel(2,”-DI”);
//—-
SetIndexDrawBegin(0,ADXPeriod);
SetIndexDrawBegin(1,ADXPeriod);
SetIndexDrawBegin(2,ADXPeriod);
//—-
return(0);
}
//+——————————————————————+
//| Average Directional Movement Index |

double pdm,mdm,tr;

int starti,i,counted_bars=IndicatorCounted();
//—-

else { PlusSdiBuffer[i]=100.0*pdm/tr; MinusSdiBuffer[i]=100.0*mdm/tr; }
//—-

}
//—- last counted bar will be recounted
if(counted_bars>0) counted_bars–;
int limit=Bars-counted_bars;
//—- apply EMA to +DI
for(i=0; i<=limit; i++)
PlusDiBuffer[i]=iMAOnArray(PlusSdiBuffer,Bars,ADXPeriod,0,MODE_EMA,i);
//—- apply EMA to -DI
for(i=0; i<=limit; i++)
MinusDiBuffer[i]=iMAOnArray(MinusSdiBuffer,Bars,ADXPeriod,0,MODE_EMA,i);
