iCustom Help - Heiken_Ashi.ex5 [2] open error
I keep getting open error for iCustom.
Heiken_Ashi.ex5 is in indicator folder.
I think I have messed up the handle. Here is handle and heiken_ashi indicator code. There arent any other handle parameters I need are there? Heiken Ashi just changes the candlesticks with a bit of math. There are no parameters needed when you load the indicator except the colour.

Check the indicator folder, may Heiken Ashi.ex5 have become two files, immediately removed Heiken Ashi.ex5 [2] file
Hi, thanks for reply
Nah there is only one. to be sure I renamed the indicator to Heiken_Ashi1 and it still came up with same opoen error [2]
Here is code that handles the indicator this is part of the include file
//| Heiken Ashi |
//+------------------------------------------------------------------+
class CiHeikenAshi : public CIndicator
{
private:
double hopen[];
double hclose[];
double hhigh[];
double hlow[];
public:
int Init(string pSymbol,ENUM_TIMEFRAMES pTimeframe,string Indicator_Name);
double Hopen(int pShift=0);
double Hclose(int pShift=0);
double Hhigh(int pShift=0);
double Hlow(int pShift=0);
CiHeikenAshi();
};
CiHeikenAshi::CiHeikenAshi()
{
ArraySetAsSeries(hopen,true);
ArraySetAsSeries(hclose,true);
ArraySetAsSeries(hhigh,true);
ArraySetAsSeries(hlow,true);
}
int CiHeikenAshi::Init(string pSymbol,ENUM_TIMEFRAMES pTimeframe,string Indicator_Name)
{
handle = iCustom(pSymbol,pTimeframe,Indicator_Name);
return(handle);
}
double CiHeikenAshi::Hopen(int pShift=0)
{
CopyBuffer(handle,0,0,MAX_COUNT,hopen);
double value = NormalizeDouble(hopen[pShift],_Digits);
return(value);
}
double CiHeikenAshi::Hclose(int pShift=0)
{
CopyBuffer(handle,3,0,MAX_COUNT,hclose);
double value = NormalizeDouble(hclose[pShift],_Digits);
return(value);
}
double CiHeikenAshi::Hlow(int pShift=0)
{
CopyBuffer(handle,2,0,MAX_COUNT,hlow);
double value = NormalizeDouble(hlow[pShift],_Digits);
return(value);
}
double CiHeikenAshi::Hhigh(int pShift=0)
{
CopyBuffer(handle,1,0,MAX_COUNT,hhigh);
double value = NormalizeDouble(hhigh[pShift],_Digits);
return(value);
}
Even when I call like this its the same error, im pretty sure its incorrect handle but how do i find out the correct handle?

It will not work without .ex5 in the data path.
And print the error to see the error code it will tell you what is.
