Intraday Intensity Index

[fercho]

Hi I've compiled the code OK but when I run it, system non-stop processing. Take a look please, thanks!

original fórmula=

IIstd = Sum21 ((2C-H-L)/(H-L))xV

IInorm = (IIstd / S21 V) x 100


protectedoverridevoid OnBarUpdate()
{

int i = CurrentBar;
while (i >= 0);

{
double high = High[i];
double low = Low[i];
double open = Open[i];
double close = Close[i];

double std=0;
double sumavol=0;

for (int k = i ; k <= (i+21) ; k++)
{
high = High[k];
low = Low[k];
open = Open[k];
close = Close[k];
double calculo = 0;
if((high-low) != 0)
calculo=(((2*close-high-low)/(high-low))*VOL()[k]);
sumavol=sumavol + VOL()[k];
std= std+calculo;
}

Plot0.Set((std/sumavol)*100);

}

}

Looks like an endless while loop to me.

What Does Intraday Intensity Index Mean?
A volume based indicator that depicts the flow of funds for a security according to where it closes in its high and low range. Calculated as:

IIstd = Sum21 ((2C-H-L)/(H-L))xV


Read as:


The 21 bars summation of (2 *Close- High - Low) divided by (High-Low) all multiplied by the Volume of each day.

NinjaScript makes that ridiculously easy to code without having to do all those resource intensive loops.

1. Create a DataSeries, and populate it with (2C-H-L)/(H-L). Let us call it IntensityAccumulator.
2. Get the sum of that using the SUM() indicator thus: SUM(IntensityAccumulator, 21)[0].

Yeap! think I´ve understood.... some F1 help and your advice, and voilá...

I've included 2 versions Standard and Normalized, put some colors too...

Thanks a lot koganam
