unhandled exception error while indicator works.

[palinuro]

Hi,

I'm getting an "unhandled exception " error when I instantiate a reference to another custom indicator, even though the code performs as expected and I have error trapping around the problem line (which doesn't catch anything).

Here's the relevant code:

private NinjaTrader.NinjaScript.Indicators.VWAPS.VWAPDaily  vwap;

....

else if (State == State.DataLoaded)
{
try{		
vwap = VWAPDaily(1,1.5,2,50,50,1,false,false,false,false,false,false,true);
}catch (Exception ex) {Print (ex.ToString());}				
}

Any suggestions would be much appreicated.

Hello palinuro,

Thank you for the post.

Currently, nothing is sticking out for me as to why you would get the error, I did want to check have you tried removing the try/catch and see what the error produced is?

If not, could you do this and provide the error message you get? The try/catch is not always the best solution but the error in the log tab or output window should be more helpful.

If this is causing a crash or something else to occur where you cannot see an error and that was the reason for the try/catch, could you instead provide an export of the indicator being used for me to review?

I look forward to being of further assistance.

Jesse,

Thanks for the response, that helped me look for the problem in the VWAP indicator, and I realized it's because it puts a button on the toolbar:

			else if (State == State.Historical)
			{
				if(!IsToolBarButtonAdded) AddToolBarButton();
			}

Is there a way to prevent that code from running if it is referenced in another indicator?

Hello

Thank you for the reply.

In this case one of the objects being used is likely null, without seeing the code in the AddToolBarButton() method I could only guess that it may be the ChartControl. Could you try the following modification to see if this resolves the error? If not, please post just the AddToolBarButton(); method and we could look at what may be happening.

else if (State == State.Historical)
{
	if(!IsToolBarButtonAdded[B] && ChartControl != null[/B]) AddToolBarButton();
}

I look forward to being of further assistance.
