A strategy I wrote worked fine for me in a live market but my partner running it in his system had problems. I later realized I was running the strategy in a chart and he was just running it from the "Strategies" tab in Control Center without having added it to any chart. This was causing it to break because something I was doing (adjusting BarsArray[0].BarsData.To) assumes it is running in a chart.

So I wrote this little helper property to help me. Maybe it'll help some of you...

 
Code
bool RunningInAChart
{
  get
  {
    return ChartControl != null && ChartControl.BarsArray != null && ChartControl.BarsArray[0] != null && ChartControl.BarsArray[0].BarsData != null;
  }
}

Quoting 
return ChartControl != null && ChartControl.BarsArray != null && ChartControl.BarsArray[0] != null && ChartControl.BarsArray[0].BarsData != null;

Ah, I have seen the test for ChartControll != null, etc., but was never sure of the point of it. Now I can see it, for something that may not be run on a chart.

Correct me if I'm wrong, but I don't think there is any point to this test in an indicator, which must be run on a chart, right? (I don't usually write strategies.)

Anyway, thanks for this!

Bob.

If you run a strategy that uses your indicator and the strategy isn't added to a chart the indicator might fail, depending on what you're trying to do.
