Simple question

[steprog]

private DataSeries highPass;
#endregion

protected override void Initialize()
{
highPass = new DataSeries(this);

Hi,
Struggling with Ninjascript her simple question: Why do you need to define
highPass as a variable and then initialize it below. It seems redundant to me it looks like highPass has already been set to a new DataSeries and why the (this)

That is because that is the way that all entities are declared. It may be possible in many cases to declare and initialize an object at the same time on one line, but that is simply shorthand that applies in those particular cases. DataSeries() takes the parent object itself as a parameter, which is why it has to be declared and initialized separately.

Thanks for the reply. I hear the words just have a hard time conceptualizing and internalizing this type of programming. I will keep at it until something "clicks". Thanks

Think of it simply this way: if the object has to take its container as a parameter, then, ipso facto, it is a circular reference. The Initialize() method is written to, inter alia, resolve such a situation, so that the object can be created.

If that situation does not exist to start with, then you should be able to declare and initialize the object at the same time.

Hello Greg,

It is good practice when setting up variables to ensure that they are setup correctly.

Also, it is to ensure that the DataSeries objects are synced up to the Primary Data Series as well.

Happy to be of further assistance.
