Custom indicator

[U0000999]

Hello, how to create custom indicator HIGH - LOW, and find average value for n periods for this indicator?

Hi U0000999, thanks for your question.

The general logic in OnBarUpdate would go something like this:

        int period = 20;
        protected override void OnBarUpdate()
        {
            if(CurrentBars[0] < period) return;

            double sum = 0;

            for(int i = 0; i < period; i++)
            {
                sum += High[i] - Low[i] / 2;
            }

            Print(sum);
        }

There are many different ways you can do this though. Take the SMA as a more complex example that sets up things that would be used on a regular basis like plots/inputs.

Please let me know if I can assist any further.

Hi Chris,
Congrats to your post no. 3000 :-) .

I just added the average and some prints.

int period = 20;
protected override void OnBarUpdate()
{
if(CurrentBars[0] < period) return;

double sum = 0;
double average = 0;

for(int i = 0; i < period; i++)
{
sum += High[i] - Low[i] / 2;
average = sum / (i+1);
}

Print("Sum: " + sum.ToString("N2"));
Print ("Period: " + period.ToString());
Print("Average: " + average.ToString("N2"));
}

Thx.
