Please help me create a Series<T> of a custom data type

[Nate G]

Hi there,
I want to create a Series<T> of custom data type for use in multiple time intervals. It's tracking some data points on a Daily, a 240-minute, and a 15-minute chart. Please see the bold red text below. Specifically the first line or bold red text. I'm not doing it correctly (duh), and for the life of me I cannot find the correct syntax. Can I declare a Series where I'm trying to so when I run the indicator it doesn't throw an "Indicator 'MarketStructure': Error on calling 'OnBarUpdate' method on bar 20: Object reference not set to an instance of an object." error?
namespace NinjaTrader.NinjaScript.Indicators
{

public class MarketStructure : Indicator

{

Series<TimeFramePoints> HTF = new Series<TimeFramePoints>; // <-- THIS LINE IS BORKED

protected override void OnStateChange()
{

if (State == State.SetDefaults)
{

...

}

else if (State == State.Configure)

{

AddDataSeries(BarsPeriodType.Minute, HighTimeframe); // BarsInProgress index = 1

}

else if (State == State.DataLoaded)

{

HTF = new Series<TimeFramePoints>(BarsArray[2]);

}

Hello Nate G,

Creating an instance of a Series<T> cannot be done in the scope of the class.

Just declare the variable and create the instance in State.DataLoaded as your are.

private Series<TimeFramePoints> HTF;

in State.DataLoaded:
HTF = new Series<TimeFramePoints>(BarsArray[1]);

I put BarsArray[1] to synchronize to that data series as there is no BarsArray[2] in your suggested code.
