Initialize Series<T>

[diff24rac]

How/Where do i initialize series?
It's the same inside State.Historical.

else if (State == State.DataLoaded)
{
IValuesTest = new Series<double>(this, MaximumBarsLookBack.Infinite);

for(int i=0; i<IValuesTest.Count; i++)
{
IValuesTest[i] = 0.0; <======= Out Of Range
}
}

in onbarupdate, when i populate some Serie<double> and run the following:

int goodBars = 0;
while(IValues.IsValidDataPoint(goodBars))
goodBars += 1;
Print("good bars onbarupadte"+goodBars);
i have "good bars onbarupdate 736" for example.

the same code inside onrender gives
"good bars render 0"

why is that?

Hello diff24rac,

Thank you for the post.

The help guide on the OnRender() method states the following:

Unlike market data events and strategy order related events, there is NO guarantee that the barsAgo indexer used for Series<T> objects are in sync with the current bars in progress. As a result, you should favor using an absolute index method to look up values (e.g., <series>.GetValueAt(), Bars.GetOpen(), etc)

More on OnRender here:

Please try using <series>.GetValueAt() instead of literal indices. Also, ensure that the custom ISeries object is initialized at the class level so that all methods will have scope for it.

namespace NinjaTrader.NinjaScript.Indicators
{
public class MyIndicator : Indicator
{
private Series<double> myDoubleSeries;
