multi-timeframes and "new DataSeries(this)"

[nicbizz]

Hi,

I'm still pretty green when it comes to programming and C#, and I'm a little unclear with it comes to using the "this" syntax.

What I'm trying to do is to add a new DataSeries for the Secondary bar object.

So for example:

protected override void Initialize()
{
     Add(PeriodType.Day,1);

}

Now, how do I create a new DataSeries to be used only for secondary Daily bars (i.e. during BarsInProgress == 1)? Would this, under Initialize() be correct:

myDataSeries = new DataSeries(this);

Thanks.

Hello,
Thank you for writing in.

'this" refers to the Indicator or strategy that the data series is being created in.
If you are wanting a secondary data series based off of different values would would need to add a secondarySeries into OnBar Update

An example of this is
[CODE]
protected override void OnBarUpdate()
if (secondarySeries == null)
{
/* Syncs another DataSeries object to the secondary bar object.
We use an arbitrary indicator overloaded with an IDataSeries input to achieve the sync.
The indicator can be any indicator. The DataSeries will be synced to whatever the
BarsArray[] is provided.*/

secondarySeries = new DataSeries(SMA(BarsArray[1], 50));
}

In my example I am getting the data series that is synced to another time frame by using the SMA indicator to get the BarsArray. You can then set the seconDarySeries accorindingly after this in OnBarUpdate.
