View Full Version : Plot My DataSeries from a Strategy

I am basing my trades on a data series I have constructed and stored in a data series "MyOpen".

If I add the command:
ADX(14).Panel = 1;
Add(ADX(14);

I can plot the ADX in panel 1. However, my trades are based on ADX(MyOpen,14). I would like to plot this rather than the base series.

I get an error if I try to use the above in the the Initialize section. Anyone know of a solution?

A workaround can be just moving the DataSeries calculations into an indicator. The indicator will just return the value of ADX(MyOpen, 14). This way you can add it to your strategy with no problem.

Something like:
Add(CustomADX(14));

The problem is a bit more complex than just adding code to an indicator.

The MyOpen data series is a calculated open from a 1 minute bar added to the Strategy that is placed on a 30 minute bar chart. I don't think this is possible to do in an indicator.

What I need to see is the computed ADX in the plot.

The code I am using to do this in the strategy:
protected override void Initialize()
{
CalculateOnBarClose = true;
Add(PeriodType.Minute,1);
}
protected override void OnBarUpdate()
if (MyOpen == null)
{
MyOpen = new DataSeries(SMA(BarsArray[0], 70));
}

if(BarsInProgress == 1 && FirstTickOfBar && FirstBar) //1 min bar
{
MyOpen.Set(Closes[1][0]);

double X = ADX(MyOpen,14);
FirstBar = false;
}
if(BarsInProgress == 0 && FirstTickOfBar) // 30 Min Bar
{
FirstBar = true;

}

Guy..
I don't think you can add custom plots from a strategy.
However some people use draw-line, or draw-dot etc. as a work-around.
CLunky for sure, but better than nothing

ATIuser was kind enought to post an example here

zoltran is correct. You cannot add a plot from a strategy.
