# Definition of what we want market data for.  We have to keep track of what ticker id
# corresponds to what symbol ourselves, because the ticks don't include any other
# identifying information. The choice of ticker ids is, as far as I can tell, arbitrary.

# Now, subscribe to ContractData incoming events.  The code passed in the block
# will be executed when a message of that type is received, with the received
# message as its argument. In this case, we just print out the data.

# respond with ContractData messages, which will be processed by the code above.
