how to get Bar.GetBar() to work in the class object

[lang0477]

Hi,

writing my first class in NT and i stuck;

I cannot figure out how to Bars.GetBar working in the class object i defined.

tTe method works perfectly fine in "protected override void OnBarUpdate()"
but if I want to use it in my own class, it would give me an compile error
"an object reference is required for non-static field, method.."
what do i need to do? tks!

public class TrendLine{


private string trendLineType;
private DateTime x1;
private DateTime x2;
private double y1;
private double y2;
private int penetrationCount;


public DateTime X1
{
get
{
return x1;
}
set
{
x1 = value;
}
}

public DateTime X2
{
get
{
return x2;
}
set
{
x2 = value;
}
}

public double Y2
{
get
{
return y2;
}
set
{
y2 = value;
}
}

public double Y1
{
get
{
return y1;
}
set
{
y1 = value;
}
}

public int GetBarAgoX1()
{
DateTime timeOfInterest;
int barsAgo;
timeOfInterest = new DateTime(2014, 2, 20, 9, 30, 0);
barsAgo= Bars.GetBar(timeOfInterest);
Return barsAgo;
}
}

Are you using a namespace that contains Bar objects?

Thank you for reply.

Yes, this class is within the default namespace of NinjaTrade.Indicator.
I couldnt find any example of using Bars.GetBar() in the user defined classes. not sure what i am missing.

namespace NinjaTrader.Indicator
{
.........
public class TrendLine{

....
}

}

It would expect this unfortunately for the custom class, but would you get the same outcome if you put your GetBarAgoX1 in the indicator UserDefined methods which is a partial indicator class?
