Custom Indicators calling other Custom Indicators

[DancesWithBears]

I am writing a system and I am trying to divide up the logic.

One custom indicator that computes moving average entry conditions has to call another custom indicator that tracks the bollinger entry conditions.

How would I call my own custom indicator?

Another related question:

I know I can call the built in standard indicators in my custom script.

But am I really calling methods on those indicators, or is it constructing the indicator on every call? That would seem expensive.

Thanks in advance..

DancesWithBears, just as you call other custom indicators as well for example -

 
double myCustomValue= MyCustomIndicator(Parameter1, Parameter2);

An indicator automatically offers a method in NinjaScript, there's no function / indicator concept as in other trading software languages. The needed cache of indicator calls is done internally by NinjaTrader.

Think the sytax looks like this

Bertrand,

Think I got it right but you can please confirm.
I construct a Custom Indicator object then call method on it.

// in my other custom indicator body
MyCustomerIndicator myCustomIndicator(Parameter1, Parameter2);

myCustomIndicator.DoThis();
myCustomIndicator.DoThat();

I just wanted to avoid creating another instance of the indicator.
But you are saying that the system won't if it sees the same constructor arguments that match an object already instantiated. (caches).

Seems logical.

DancesWithBears, yes that is correct, you could also use the UserDefinedMethods for this purpose - http://www.ninjatrader-support.com/H...verview45.html

That was my next question and you already answered it.

Tausend Dank! A thousand thanks! Thanks very much!

Problem exporting when I use

Getting "error compiling sources" when I try to export now.
After I put my functions in UserDefinedMethods.cs.

hmm..

Yes, unfortunately you can't export UserDefinedMethods
