I'm trying to register a callback:

def my_callback(msg): print msg

con = ibConnection() con.register(my_callback, message.tickPrice)

This doesn't work. But it is used like that in the examples and the docstring of register seems to indicate that this should work.

Alternatives that work are: - con.register(my_test, (message.tickSize,)) - con.register(my_test, message.registry['tickPrice'])
