That all looks correct!

Try adding useDispatcher=1 as a param to wrap. That will cause the object
to use a "debug" dispatcher, and should spew print statements to
win32traceutil - ie, the same as if the object was registered with "--debug"
(but as this object is not registered at all, --debug isn't an option; the
param to wrap is though).

Ack - that can't be good. What is the makepy generated code for
OnQuoteData?

It all looks ok to me, so I'm not really able to offer much more help at
this stage.
