Why don't you use buffers?

He is probably trying to have it buffer independent

Hello,
Im having issues with this function and im not able to get the right values for my EA. 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=iStdDev(NULL,0,StdDevPeriod,0,MODE_LWMA,PRICE_MEDIAN,i);
}
for(i=0; i<StdDevCount*2; i++)
{
BandsStdDevBuffer=iBandsOnArray(StdDevBuffer,0,StdDevBolPeriod,StdDevBolDeviation,0,MODE_UPPER,i);
Print("StdDevBuffer for ",i," = " , StdDevBuffer);
Print("BandsStdDevBuffer for ",i," = " , BandsStdDevBuffer);
}
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...
