dataseries initilization

[ballboy11]

I am almost done programming this indicator but I don't know how to initialize these


#region Properties
[Browsable(false)]
[XmlIgnore()]

public DataSeries SMI //HOW DO I INITILIZE THESE
{
get { return Values[0]; }
}

[Browsable(false)]
[XmlIgnore()]
public DataSeries SMIAvg //AND HOW DO i INITIALIZE THESE
{
get { return Values[1]; }


private DataSeries relDiff;
private Dataseries diff;
private Dataseries avgRel;
private DataSeries avgDiff;



}

Hello ballboy11,

Thank you for your post.

Please provide further details on this matter. Are you attempting to make the DataSeries as user defined inputs? Are these plots you wish to expose to the UI for user editing?

If possible please provide the full indicator code you are using. You can attach your indicator to your response by going to File > Utilities > Export NinjaScript > Export selected source files > select your Indicator > select the right arrow > Export. The file will be located under (My) Documents\NinjaTrader 7\bin\Custom\ExportNinjaScript.

I look forward to your response.

Hello ballboy11,

Thank you for your response.

To Initialize a DataSeries in NinjaTrader 7 you must do so within the Initialize() method of NinjaScript and set it to the calling NinjaScript object with 'this'. For example:

protected override void Initialize() 
{ 
    myDataSeries = new DataSeries(this); // "this" refers to the indicator, or strategy
                                        // itself. This syncs the DataSeries object
                                        // to historical data bars
}

This is taken from the following link on the DataSeries Class: http://ninjatrader.com/support/helpG...ries_class.htm

Please let me know if you have any questions.

Hi,

Is there a dataseries type which is can work without sync?
Lets say i open 30 min ES chart with session template ETH.
In one of my indicator i want to calculate and plot SMA(20) for both ETH and RTH.
So i want to check time hour and minute if it's in regular trading hour i want to add close value to in a notSyncDataseries user defined variable (which is must not be work sync).
and send this dataseries to SMA(notSyncDataseries, 20)

Why need this?
If there is no support that type dataseries in ninja.
I have to store related close values on a arraylist.
Then write custom method that calculating sma values (beucase Indicator.SMA method needs dataseries because of that i can not use it)
ıf there is necessary revers arraylist before send to custom SMA method.

Shortly i need a store values on a series but it don't have a value for each bar.

Thanks,
Aytac

Hello aytacasan, thanks for your post.

The AddDataSeries method will allow you to add a data series with a different session template with this overload:

AddDataSeries(string instrumentName, BarsPeriod barsPeriod, string tradingHoursName)

We also have an example here showing how to sync a data series to a second time frame:

Please review this sample to see if it fits the requirement. If you needed an SMA on both RTH and ETH, you could also use a simple time filter to read the SMA at a certain time. We have an example of a time filter here:

Please let me know if I can assist any further.
