Is it possible to create New DataSet from History Data Provider's class?

I use this code for it (and call it only once from GetHistoryInternal()) :
CODE:
private void AddDataSet() { DataSet dataSet = new DataSet(); dataSet.Name = "Tinkoff"; dataSet.PreferredDataProviderName = Name; dataSet.ReadOnlySymbols = true; dataSet.IsUserCreated = false; dataSet.Glyph = Glyph; dataSet.DataProvider = this; app.AddLogItem(Name, "Creating dataset...", Color.Gray, null, this); app.DataSets.Add(dataSet); }


but nothing to happen.
What's my wrong?

More context required.

For example, Where is the code running? i.e., is it in a class that derives from DataSetProviderBase?

No, it is from base class for history data provider.

CODE:
public class TinkoffHistoricalDataProvider: DataProviderBase

Like Cone suggests, DataSets should be added by a DataSetProvider.

Are you developing a broker provider for the Russian brokerage Tinkoff? If/When it reaches production quality, would you be interested in submitting it as a third party extension to our marketplace? You could then earn money if WL7 subscribers from Russia purchase your extension.

If you sell your extension through our marketplace and web site, we collect 20% of payments and forward the remaining 80% to you.

I mean do you have any examples or best practices how it to do - implementing some key api to protect extension software from free using?
Where I can see it?

We don't publish such guidelines or examples because protection techniques are up to you as the developer.
