I'm sorry I can't run the code you posted.  I don't seem to have any
modules named "request" on Python 3 or Python 2 and your Trader.py seems
to require it.

You might want to remove the url downloading and Beautiful Soup stuff
and put in some kind of nop loop instead to simulate it.  For example,
in the Trader module you can remove everything in run() and just have it
return dummy values, maybe putting in a delay to simulate the work of
downloading and parsing.

Just an observation from looking at the main module code.
You only need to attach a callback to a signal once.  output_slot()
seems to attach the callback each and every time the timer fires.  This
is surely wrong.

I'll give it some further study this evening.
