According to Mathworks release notes it looks like some of the Trading Toolbox functionality has moved into Datafeed Toolbox and some functionality is going into the file exchange:
"Functionality moving to File Exchange:
- Functionality for creating connections to the following data providers has moved to File Exchange on MATLAB® Central™. You can access the documentation from the prior release."
Where in the file exchange repo can I actually find these files, for example for data provider connections like bloomberg, factset, iqfeed, interactive brokers, fix flyer?
