need help with iBandsOnArray()

New comment
 

Hello,

 

Thank you in advance for looking this up.

Im looking to get the the StdDev cross of the upper bollinger band on my ea like the picture bellow:

 

 

  

 So far i wrote this code but i cant get the upper bollinger band(always return 0) value to compare the variables... Could anyone point me in the right direction?? Thank You 

 

extern int StdDevPeriod = 14;
extern int StdDevBolPeriod = 21;
extern double StdDevBolDeviation = 1.5;

double StdDevBuffer[],BandsStdDevBuffer[];

int init()
{  
   int StdDevCount = MathMax(StdDevPeriod,StdDevBolPeriod);
   ArrayResize(StdDevBuffer,StdDevCount*2);
   ArraySetAsSeries(StdDevBuffer,true);   
   ArrayResize(BandsStdDevBuffer,StdDevCount*2);
   ArraySetAsSeries(BandsStdDevBuffer,true);   
}

int StdDevSignal()
  {

   int StdDevCount = MathMax(StdDevPeriod,StdDevBolPeriod);   

   for(i=0; i<StdDevCount*2; i++)
     {
      StdDevBuffer[i]=iStdDev(NULL,0,StdDevPeriod,0,MODE_LWMA,PRICE_MEDIAN,i);
     }

   for(i=0; i<StdDevCount*2; i++)
     {
      BandsStdDevBuffer[i]=iBandsOnArray(StdDevBuffer,0,StdDevBolPeriod,StdDevBolDeviation,0,MODE_UPPER,i);             
      Print("StdDevBuffer for ",i," = " , StdDevBuffer[i]);
      Print("BandsStdDevBuffer for ",i," = " , BandsStdDevBuffer[i]);
     }

   Print("StdDevBuffer[0]  = ",StdDevBuffer[0] , "|| BandsStdDevBuffer[0] = " , BandsStdDevBuffer[0]);
   
   if(StdDevBuffer[0] > BandsStdDevBuffer[0]) return(1);
   else return(0);
  }

 

 I also have this results from the terminal when running the code...
