NT8 How to make plot public & accessable to other indicators

[saturntd]

I would like my indicator plot to be available to other indicators under Input Series->Parameters->Plot
If I look at the Ninja SMA plot: AddPlot(Brushes.Goldenrod, NinjaTrader.Custom.Resource.NinjaScriptIndicatorNa meSMA);
I don't see how to do this in my own indicator. Please explain.

are you talking about dataseries information?

[ballboy11]

// public class YourIndicatorName: Indicator Your indicatorName
// {
//}


AddPlot(new Stroke(Brushes.Tomato, DashStyleHelper.Solid, 2), PlotStyle.Hash, "F500");


[Browsable(false)]
[XmlIgnore]
public Series<double> F500
{
get { return Values[0]; }
}

double dAnswer;

Now when you are accessing the data you will have a varialbe

dAnswer = YourIndicatorName(Your varialbe Name).F500[0];

Thanks Ballboy11

Hello saturntd,

Ballboy11 is correct. An example of this is the Avg plot series in the MACD indicator included with NinjaTrader.

Also, below is a public link to the help guide on 'Exposing indicator values that are not plots' for other things you may want public that are not series.

// public class YourIndicatorName: Indicator Your indicatorName
// {
//}


AddPlot(new Stroke(Brushes.Tomato, DashStyleHelper.Solid, 2), PlotStyle.Hash, "F500");


[Browsable(false)]
[XmlIgnore]
public Series<double> F500
{
get { return Values[0]; }
}

double dAnswer;

Now when you are accessing the data you will have a varialbe

dAnswer = YourIndicatorName(Your varialbe Name).F500[0];

And in this case I can put the value for Plot in OnBarUpdate like this: Values[0][0] = the_value_for_plot

But, when I use OnRender for my indicator and don't use OnBarUpdate at all? How can I put the value in "Plot" on my chart in this case?

Hello handlar,

OnRender() happens in another thread.

You would need to use .GetValueAt() or TriggerCustomEvent() to synchronize the series first.
