Using Simulink to Model and Simulate Financial Securities

I have a few questions about using Simulink to model and simulate financial derivatives.

1. Is there a ‘financial toolbox’ in Simulink with ‘blocks’, which would allow me to model financial derivatives (e.g. - options, derivative spreads, etc.)

2. Is there a way to use data stream(s) from Interactive Broker's market data or historical data feed, subscribed from within the Matlab's data feed toolbox as a source in a Simulink model (e.g. - similar to sine waves, square waves, etc.)

3. Can I use a flat file containing recorded price data as a Simulink source?

4. Can I use a MySQL database query as a Simulink source?

5. Can I call Java beans and/or Spring services from Simulink model?

6. If there is no ‘financial toolbox’ available. Is it possible to contruct one?

Thanks in advance.
