Detect Chart Type

[reynoldsn]

I'm trying to get my strategy to detect what chart type is being used.

I finally got this to compile, but it doesn't work.

if (CurrentBar > 1)
{
if (BarsArray[0].BarsPeriod.BarsPeriodType != BarsPeriodType.PointAndFigure)
{
throw new Exception("This strategy requires a Point and Figure chart. Please apply it to a PnF chart.");
}
}

Any help is appreciated.

I have tried:

string myType = BarsArray[0].BarsPeriod.BarsPeriodType.ToString();
Print("myType: " + myType);

if (BarsArray[0].BarsPeriod.BarsPeriodType != BarsPeriodType.PointAndFigure)
{
Print(String.Format("You chose {0}. You need BarsPeriodType.PointAndFigure.", myType));
}

and that seems to work for me. Output:
myType: Second
You chose Second. You need BarsPeriodType.PointAndFigure.

Not entirely sure you need to throw a new exception to detect what type you are using. If you need it to prevent the strategy from being used on the other hand, I don't have too much experience with. I usually see exceptions being used with a try catch block...but the consensus on Stack Overflow seems to be that "throw new exception" is a generally bad idea.
