Assigning values from a method to a dataseries or array

[jeddy0510]

Hi,
I have created a simple function (method) that retruns the double value of a fast moving EMA when it crosses a slower Simple Moving Average. Lets assume this method is named Crossover()
What I now need to do is somehow assign the values of Crossover() as they are occuring into some sort of dataseries or array so that can be called on in a strategy in a systematic fashion, e.g
If (Crossover() [1] < Crossover() [2])
{
Go Long
}

My question is how do you assign values from a method to a dataseries or array so that they can be called up from historical data numbering from [0] current value generated by method to [1] last value to[2] second last value and so on....
I would like the assigning to the dataseries or array to commence an hour before the start of the trading day and to end at the close of the trading day.

jeddy0510, I suggest you check into this sample to see how to create and set custom dataeseries objects holding your double values so they could be accessed historically as well in your code:

Assigning values from a method to a dataseries or array

Bertrand,
I assign values to the array with DataSeries.Set(). But when I try to "Print" or "Get" a value other than index 0, (DataSeries[0]), i.e. DataSeries[1], DataSeries[2]..., etc. Those other indexed places of the array do not have any values (zero)... Please help.
It seems that the values are not saved in the array. Is this because of OnBarUpdate?

*****Update*******
Just solved it. The steps are basically:

1) Declare the variable (data structure) DataSeries:
private DataSeries xData;

2) Initialize the variable DataSeries:
xData = new DataSeries(this);

3) Assign the values (with your logic) using DataSeries.Set():
xData.Set(xData[1] - yData[1]);

4) Print/Plot them:
Print("xData = " + xData[0].ToString());
Plot0.Set(xData[0]);
