AddRenko() instrument name in Strategy Analyzer Optimization

[mvdn73]

Hello, I have created a strategy that adds a renko data series to to the OnStateChange() method in the State.Configure block as shown below

AddRenko(this.Instrument.FullName, 3, MarketDataType.Last);

When running optimizer in the Strategy Analyzer the follow error occurs:

"Error on calling 'OnStateChange' method: Object reference not set to an instance of an object."

It appears that "this.Instrument.FullName" only works during the first iteration in optimizer but is null after. When hard coding the contract in place it works. Is this a bug or expected?

Hello mvdn73,

Thank you for your note.

You should hardcode the instrument in your AddRenko call, as this.Instrument.FullName is not guaranteed to be known.

At the following link, see the 3rd warning.

I will add your vote to the feature request which covers dynamically adding data series.
