Just wondering why do you need this? What are you trying to do? Maybe I can help you if I know what you are trying to do.?
I think what you are trying to do has been removed. Maybe you can get what you need by this below??
contract = Stock(symbol='TSLA', exchange='SMART', currency='USD')
ib.qualifyContracts(contract)
ticker = ib.reqMktData(contract=contract,genericTickList="",snapshot=False,regulatorySnapshot=False)
def onUpdateEvent(ticker):
? ? print(ticker)
ticker.updateEvent+=onUpdateEvent
