Hi Puravida,

Thanks for posting.

You can use the SUM() feature with NinjaScript to calculate the Open and Close of a time frame.
A sample of this code looks as such

// Prints the current value of a 20 period SUM using Close price type
double value = SUM(Close, 20)[0];
Print("The current SUM value is " + value.ToString());

If you are looking to get the Open minus Close price, you can look into using the data series. Below is a link to a reference sample of how to use the data series.

If you scroll down to the bottom, you can read the following statement which didn't worked for me:

protected override void OnBarUpdate()
{
    // Calculate the range of the current bar and set the value
    myDataSeries.Set(High - Low);

This one gives me a compile error... so i "fixed" it to:

protected override void OnBarUpdate()
{
    // Calculate the range of the current bar and set the value
    myDataSeries.Set(High[0] - Low[0]);

Am i missing something or is it really a typo in the documentation?

Hi Puravida,

Thank you for pointing that out. I have sent that in to development and they are looking into it.
