reqMktData() when given a BAG contract returns the spreads on the bid and the ask. It also returns some size information, which I assume is the spread on the sizes when the spread on the bid/ask changes, although I am not sure about this aspect.

Attached is a short working example in Java based on the "ExampleBase" series of examples included in the IB API source code.  Just replace the hard-coded IP address to one wihch works for you.  This example creates an ES calendar spread, and then calls reqMktData() on the BAG contract; the rest of the program simply prints the bid/ask spread to stdout.
