Hello,
How does one use a NullAlphaModel with the other elements of QCAlgorithmFramework? It seems that a normal AlphaModel will return an array of Insights in the Update method of the AlphaModel, and that these are automatically passed along into the RiskManagement and ExecutionModels. With a NullAlpha model, how do I pass this array of insights into the ExecutionModel?

With the NullAlphaModel, we do not pass an array of insights into the portfolio construction model. We simply construct the portfolio based on the available securities.
This logic can be extended to any model type since all framework (but Portfolio Selection) models can access the available securities through OnSecuritiesChanged event handler.

For anyone else who has this problem, Alexandre answered another question I asked in a separate thread, where I went about solving my problem in a different manner. Here's a link to that thread in case anyone comes across this post with a similar problem. Thank you Alexandre!
