Intraday Intesity problems / calculation returns NaN

[j2496i]

Hi,

I am trying to code an Intraday Intensity oscillator, involving only some very simple arithmetic - however, the calculation is failing. I have been adding parts of the calculation into a test script to pinpoint where the issue is, and it appears to be with the following division for 'tempval3':

double tempval1 = ((2*Close[0]) - High[0] - Low[0]);
double tempval2 = (High[0]-Low[0]);
double tempval3 = tempval1/tempval2;
temp.Set(tempval2);
Print(tempval3);
I_Intensity.Set(temp[0]);

I can plot tempval1, no problems. The same applies to tempval2, but no plot shows for tempval3.

In the output window, I notice that tempval3 is returning lots of -1 and 1 values, and also NaN occasionally.

Any ideas why this could be - as far as I can see I am only asking for the most basic of arithmetic here?

Thanks in advance

Julian

Hello Julian,
Thanks for writing in and I am happy to assist you.

In case High and Low are equal you are then dividing tempval1 with 0 (zero). In such case you will get NaN.

You can filter your code with

if (double.IsNaN(tempval3))
{
   //do something
}

Please use the Print() function to debug the code throughly. Please go through this post which discusses how to debug in NinjaTrader http://www.ninjatrader.com/support/f...ead.php?t=3418

Please let me know if I can assist you any further.
