Operator Error Message

[Mike Winfrey]

I am writing an indicator that is a variation of the CCI. The CCI normally uses typical which is (high + low + close) / 3. I want to redefine typical to be
myTypical = (Max(High, 3)+Min(Low, 3)+Close) / 3

Simple enough but I don't know how to work around the strongly typed C#.

These are the code snippets where I attempt to do this.
Variable Declaration...
private DataSeries myTypical;

protected void RedefineTypical()
{
myTypical.Set((Math.Max(High[0], 3)+Math.Min(Low[0], 3)+Close[0]) / 3);
}
Ok I know you know what's coming next. I get a compile error stating Operator '+' cannot be applied to operands of type 'NinjaTrader.Data.lDataSeries' and 'NinjaTrader.Data.lDataSeries'

Also I get an error "the best overloaded method match for system.math.mas(sbyte,sbyte) has some invalid arguments. argument '1' cannot convert from ninjatrader.dat.idataseries to sbyte.
Thank you for your help.
Mike

Code line below has no error. Just click on the error message, it will bring you to the erroneous code line.

Thank you for the timely reply, especially at midnight. Holy cow...don't you sleep? Incredible. Anyway, I know about double clicking on the error message which is how I found out where the error is and the error is just as I described. However, I notice that I sent you the wrong code. That error was accurate for that code but obviously doesn't apply now. Don't know what I was thinking but anyway can we please start over.

Here's the real code that I want to work...a screen shot of this code and the error are attached. The screen shot also shows how I want to use this method and is at the bottom of the code.

#region Variables
private int period = 14;
private DataSeries myTypical;
#endregion

protected void RedefineTypical()
{
myTypical.Set((Math.Max(High, 3)+Math.Min(Low, 3)+Close) / 3);
}

protected override void OnBarUpdate()
{
if (CurrentBar == 0)
Value.Set(0);
else
{
double mean = 0;
for (int idx = Math.Min(CurrentBar, Period - 1); idx >= 0; idx--)
mean += Math.Abs(myTypical[idx] - SMA(myTypical, Period)[0]);
Value.Set((myTypical[0] - SMA(myTypical, Period)[0]) / (mean == 0 ? 1 : (0.015 * (mean / Math.Min(Period, CurrentBar + 1)))));
}
}

Here is one problem, you as passing in a DataSeries object of high prices (High) to Math.Max() instead of a double value.

Math.Max(High[0], 3)

instead of

Math.Max(High, 3)

[Mike Winfrey]

Thank you...i made the change as you suggested which looks like this.

myTypical.Set((Math.Max(High[0], 3)+Math.Min(Low[0], 3)+Close[0]) / 3);

and now it successfully compiles. I have other issues now but i'll work on them a bit before I bother anyone with it.

Thanks,
Mike
