Bars object question

[The Kid]

Hello,

Hello, I'm writing my first strategy and can't find in the reference guide the methods of the Bars object.

Perhaps someone out there can help me.
If I want to get the Open of a bar n barsago how would I do that?

myBars[barsago].Open doesn't compile saying that myBars[barsago] is a double.
If so what double is it? The Open, Close, High, Low, Volume?

Thanks so much

Hi The Kid,

I would recommend reviewing this link and the associated tutorials first -

Then,

to get the open price for example for 4 bars ago, you can simply write

 double myOpen = Open[4];

Hi there, I'm using more than one bar object in my strategy so calling Open on it's own will not be in the correct context for my secondary Bars

I have gone through the material in the link already, but don't see a solution there.

I have a feeling I am not using the correct Objet type.
Here's one of the things I am doing:

publicdouble sum(Bars x,int windowSize)
{
double theSum = 0;
int i;

if ( x.Count <= windowSize ){
for (i = 0;i < windowSize;i++){
theSum=theSum+ x[i];
}
}
return theSum;
}

I am calling this function as follows:

sum(BarsArray[1],2000);

I was expecting x to be of type Bars and to have Open, Close, High, Low and Volume members, but it doesn't seem to have any of that.

I don't see the Bars object explained in the help on the web. Quite possibly I am not looking in the right place. I guess I could resolve all this if you could point me to a comprehensive document with all objects and members explained.

Thanks so much
