Problem with referencing custom indicator

Dear Trader,

Could you please provide us with more information regarding your issue?

Do you receive any error messages? 

When you write for example a single print method in the OnTick() method, does it still not work?

Did you have any problems performing any of the steps described in the Referencing Custom Indicators section of our support site? 

The following code snippet illustrates the use of an indicator in a cBot.

        private SampleSMA sma;

        protected override void OnStart()
        {
            sma = Indicators.GetIndicator<SampleSMA>(Source, SmaPeriod);
        }

        protected override void OnTick()
        {
            Print("{0}", sma.Result.LastValue);
        }

My code is exactly the same with what you wrote but different custom indicator.

I don't have error messages and everything seems to be fine. The problem is that when I include the initialization line  bulls = Indicators.GetIndicator<ElderRay>(Source, 13); in OnStart() ,nothing is executed in OnTick(). I

t's like compiler finds some problem in this line and doesn't look further.

Dear Trader,

In the log you will see the message:

Crashed in OnStart with ArgumentException: Incorrect parameters count. Parameter name: parameterValues

This means that when you call an indicator you used an incorrect number of parameters, in your case, you need to add a parameter to this line OnStart():

bulls = Indicators.GetIndicator<ElderRay>(Source, 13, MovingAverageType.Exponential);

In addition, you need to switch the parameters on the second custom indicator you referenced

// currently
//you defined it 
example(String x, int y)

//you are calling it 
example ( 35, "hello");

A very simple and quick way to troubleshoot/check your code is to use the Print() method between the lines of your code to verify that the code reach these lines with an expected result.
