Your Object Model

[achalk]

In my class I want to call the built-in Add() method. However, that method is a protected member function of IndicatorBase. If I specify that my class is derived from indicator base NT also wants me to define Initialize() and OnBarUpdate(). Can I go ahead and do so, defining them thus:

protected override void Initialize() {}
protected override void OnBarUpdate() {}

That is, effectively as no-ops, or will this hide the implementation in my indicator?

Thks.

Unfortunately we don't support the creation of custom classes (it is possible just not supported).

Might I ask what your end goal here is so I can possibly provide a work around or alternative solution?

Is there a reason you can't create a new indicator and then perform the desired operations with in the indicator? Doing this would allow you access to using the Add() in Initialize()

Thanks for your reply Lance. I create a class in my custom indicator. In the constructor I want to add the security name passed in the constructor to a chart and also plot it. So I want to call, for example,

Add("SPY", PeriodType.Day, 1);
Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Plot1"));

in my constructor. As I am creating a portfolio of several of these securities it good to encapsulate the calls a function call (the constructor).

Thanks for this information.

The only supported way we would have to do this would be to hard code Add() all the instruments in the Initialize() of the indicator.

This is because Initialize() can get called at times other than what you might expect. For example, opening up the indicators window can cause Initialize() to be called. If these series are not hard coded the series may not be added properly.

Let me know if you think I misunderstood your request.
