ATR plot

[cptrader]

I wish to create an indicator that plots a dot on the chart 1 ATR(10) above closing prices. Any suggestion to modify my efforts

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Dot, "Plot0"));
CalculateOnBarClose = true;
Overlay = true;
PriceTypeSupported = true;
}
protectedoverridevoid OnBarUpdate()
{
Plot0.Set(Close[0]+ATR(10));
}

You want to use ATR(10)[0] instead to access the latest ATR value.

ATR Plot

That works well. Thanks. I tried to plot a second plot but got error.
Can I do this or do I need to create a new indicator?

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Plot1"));
CalculateOnBarClose = true;
Overlay = true;
PriceTypeSupported = true;
}
protectedoverridevoid OnBarUpdate()
{
Plot0.Set(Close[0]+ATR(10)[0]);
Plot1.Set(Close[0]-ATR(10)[0]);
}

To add a second plot you need to add it into the Properties region of the code as well. Please expand the properties region and duplicate a second set you have down there. You will need to increment the Values[0] to Values[1]. I suggest you open up the MACD indicator and take a look at how it is done there.
