Series<double> for secondary data series?

[iq200]

Hi,
I have a secondary data series in my indicator and I want to create a Series<double> which stores information for this secondary series rather than the primary data series.
I am declaring the series as:

private Series<double> numberSeries;

I create the series in State.DataLoaded:

numberSeries = new Series<double>(this, Period <= 256 ? MaximumBarsLookBack.TwoHundredFiftySix : MaximumBarsLookBack.Infinite);


I then create the secondary data using AddDataSeries

So my question is how can I access the numberSeries so that [0] element is the value for the current secondary bar and [1] element is the previous element etc... for the secondary data series?

It's all working except that when I access element [1] of numberSeries it's accessing the data corresponding for the previous bar of the primary data series rather than the previous bar of the secondary series.

Regards,
iq

Hello iq200,

Thanks for your post.

A Series object can be synced to a NinjaScriptBase (using "this") or by specifying the Bars object to be synchronized with. For example:

mySeries = new Series<double>(BarsArray[1], MaximumBarsLookBack.Infinite);

Documentation for Series<T> can be found here - https://ninjatrader.com/support/help...8/?seriest.htm

I look forward to being of further assistance.

Hi Jim,
Many thanks for getting back.
Funnily enough I was going to post that I had just found out the information on your help pages:

I was in the process of testing it out

Hi Jim,
When it's synchronized, does that mean I don't need to manually sync mySeries[0] with Closes[1][0] in OnBarUpdate? Can you confirm that the data in mySeries is automatically synced with BarsArray[1]?

If you do not specify the bars object, the series will sync with the primary data series, which is BarsArray[0]. If you want a custom series to be in sync with an added bars object, you must use one of the overloads that allows an argument for the bars. The available constructors are listed and explained on this page:
