Added indicator isn't plotting the line

[Chippy]

I added a data series and ATR indicator to my strategy. I am able to print atr1[0] to the output panel (with accurate values), but only the indicator panel is painting to the chart. Not the graph of the values. My primary series is a range chart. The added series is a 1-minute chart if that makes a difference. The indicator labels with the default values (like they do whenever there's an error) and are not in range of the atr1 values.

Here is the code snippet:

}else if (State == State.DataLoaded){
atr1 = ATR(BarsArray[2],20);
atr1.Plots[0].Brush = Brushes.Green;
AddChartIndicator(atr1);

Hello Chippy,

When using indicators that target a secondary series those cannot be added using AddChartIndicator, there is a note about that in the AddChartIndicator page. If you wanted to plot the atr value you would need to use AddPlot to create a plot and then assign the ATR to that plot:

if(BarsInProgress == 0) Value[0] = art1[0];

That would create a consistent plot of the atr values at the time of the primary close.

Thanks Jesse, that's not going to work for me... this is for a strategy. My understanding is that AddPlot will only plot to the primary panel.

What I'm trying to do is add a simple ATR indicator (in its own panel on the chart page) to my strategy but to do that the ATR method requires the data series (since it's a different series than the primary data series). The only way I know how to do that is via AddDataSeries. Is there another way I can do this?

Hello Chippy

You can add indicators using the strategy just not for ones that use a secondary series, in your use case you can't add that indicator visually.

You can see the following link for an example of using a dummy indicator to plot in a secondary panel. The strategy would still need to add a series and set it from the BarsInProgress 0 for that to work.

Hi Jesse. I found that link just before I sent my last post and have been tinkering around with it but I just don't get it. Can you explain this:

private SamplePanelPlot samplePanelPlot;

It looks like "SamplePanelPlot" is a type?? That doesn't make sense.

and then this looks like a method calling itself. Is this recursive?:

samplePanelPlot = SamplePanelPlot();

Hello Chippy

private SamplePanelPlot samplePanelPlot;

This is a variable definition, the variable name is samplePanelPlot and the type is SamplePanelPlot . SamplePanelPlot is an indicator that comes with that sample.

samplePanelPlot = SamplePanelPlot();

This is the same as how you would call any other indicator, for example a similar code would be:

private SMA mySma;
mySma = SMA(12);

Thanks... I would need to alter any indicators I want to use for that purpose, to include the strategy method. More trouble than it's worth. Thanks anyway.
