State.DataLoaded or State,Configue

[fluke]

Hi

Just to further my understanding as I study ninjascript:

I have seen the MACD indicator written including the price series included in both State.Configure and also in State.DataLoaded

eg
else if (State == State.DataLoaded)
{
fastEma = new Series<double>(this);
slowEma = new Series<double>(this);
}

or

else if (State == State.Configure)
{
constant1 = 2.0 / (1 + Fast);
constant2 = (1 - (2.0 / (1 + Fast)));
constant3 = 2.0 / (1 + Slow);
constant4 = (1 - (2.0 / (1 + Slow)));
constant5 = 2.0 / (1 + Smooth);
constant6 = (1 - (2.0 / (1 + Smooth)));

fastEma = new Series<double>(this);
slowEma = new Series<double>(this);
}



How does this change the behavior of the code written?
thanks

Hello fluke,

Thanks for your post.

When creating the Series object by syncing to the NinjaScript object using "this," the code may work the same without issues seen. As a best practice, it would be advised to create the Series object in State.DataLoaded since creating the series generally depends on data being available to synchronize with. If you used a Bars object to build the Series object in State.Configure, you would certainly run into issues.
