broker parameters-commission

[siavash]

How can I define commission parameter when instancing broker object? I coded that like below but it issues error.

cerebro.broker = bt.brokers.BackBroker(commission=.02)

@siavash I think you can do something like this

from backtrader.brokers import BackBroker

myBroker = BackBroker()
myBroker.setcommission(commission=.02)
cerebro.broker = myBroker
