zero divide error on m1 chart !!

[Dimitar Pavlov]

Hi can anyone fix the zero error divide ( the error is only when the indicator is put on m1 chart)

Thanks

Please post the line numbers behind the zero divide error...

This calculation of Minr seems to result in a zero

Minr = 0.2 * (Temp / 5.0);

And this causes the zero divide error in the following two lines

AboveBuff[i] = 3.0 * (High[i]  - Main) / Minr;

BelowBuff[i] = 3.0 * (Low[i]   - Main) / Minr;

thanks i fixed it :

instead of   Temp = 0.0

i did

Temp = 0.000001

Another solution is :

Minr = 0.2*(Temp*(MathPow(5,-1));
AboveBuff[i] = 3.0 * (High[i]  - Main) * (MathPow(Minr,-1));
BelowBuff[i] = 3.0 * (Low[i]   - Main) * (MathPow(Minr,-1));

Always good to check any divisor in MQL that could give you a zero error. I always use a simple function:

double dblNotZero(double aValue)
{
   if (aValue==0) return(0.00001);
   else return(aValue);
}

Then pre-check any division that may produce a zero:

 

X = Y / dblNotZero(Z);
