Hi all, thanks in advance for your help.

I'm trying to set a custom fee, but having difficulties applying it

I've got two stocks in a list 'symbols', and I've tried sticking the lines below in the def initialize function of my main class but without luck.  Ideally I want to set a single global transaction fee for all transactions. Help much appreciated! 

self.symbols[0].FeeModel = ConstantFeeTransactionModel(1.0)
self.symbols[1].FeeModel = ConstantFeeTransactionModel(1.0)
