Error compiling user indicator

[iq200]

Hi,
I wrote an indicator called SRMomentum which I am trying to call from another indicator called SRMomentumSetup.
SRMomentum is working fine as expected and has the following constuctor

public SRMomentum SRMomentum(int period)
{
return SRMomentum(Input, period);
}

In SRMomentumSetup, I declare my class variables:

SRMomentum lowMomentum, highMomentum;

and instantiate the objects in State.DataLoaded:
lowMomentum = new SRMomentum(LowPeriod);
highMomentum = new SRMomentum(HighPeriod);

However I am getting the error for both these lines:

'Ninjatrader.NinjaScript.Indicators.SRMomentum' does not contain a constructor that takes 1 arguments

Any ideas what the problem could be please?
Regards,
iq

Hi iq, thanks for your note.

The "new" keyword should not be used to instantiate a NinjaScript object. NinjaTrader calls "new" internally and this is where the NinjaTrader generated code at the bottom of all indicators comes into play. Incidentally, no custom constructor is needed. If you remove "new" from the two lines and look at the parameter list that SRMomentum can take then the code will compile correctly. It likely needs an input series, such as Close for example.

e.g. lowMomentum = SRMomentum(Close, LowPeriod);

Take a look at the parameter list when you type "SRMomentum(", the editor will tell you all the parameters needed.

Best regards.
