Howto access indicator data series

[TraderFrank]

Hello,

I'm writing an indicator script for NT8 which wants to access the input series selected by the user in the indicator property window of a chart window. E.g. opening indicator dialog of chart window, add new indicator and select for indicator "Input series" a nested indicator WMA(EURUSD(1 Minute), 14).
Within my indicator script access to Input[0] seems to return the Close value, but not the WMA(14) as selected in the indicator properties.
How can I access the configured input series w/o hardcoding WMA(14) in the script? "Input" series does not work.

Thanks
Frank

Hello TraderFrank,

Thank you for your note.

The behavior you see is contrary to what should occur. Can you advise if this is NinjaTrader 7 or 8?

Can you attach a screenshot of the settings in the Indicators menu of the chart?

Hi Patrick,
thanks for your fast response. I think I did not tell the whole story, which might explain why it does not work.
In my indicator I'm calling a function asynchronously from a button I have installed in the chart window.

private
void OnCallbackData(object action)
{
var delta = new double[inputSize];
for(int bar = 0; bar < inputSize; bar++)
delta[bar] = Input.GetValueAt(bar);
}
What I see is that Input seems to return CLOSE, but not WMA(EURUSD(1 Minute), 14) I have configured in the indicator property "Input series". I assume due to the asynchronous call, the WMA(EURUSD(1 Minute), 14) wasn't calculated when I want to access it? Can you confirm!
If that's the case, what would be the right approach to access another indicator value from a asynchronous indicator function?

Thanks
Frank

Hello TraderFrank,

Thank you for your patience.

In this case we would need to hard code the indicator into the code.

You could instantiate the indicator to help preserve performance. For example:

private WMA myWMA;

Then in Initialize():

myWMA = WMA(14);

And in OnBarUpdate:

myWMA.Update();
myWMA[0];
