Hello,

Fees, fill models, slippage models, are predefined in the brokerage models (DefaultBrokerageModel), Interactive Brokers (InteractiveBrokersBrokerageModel), FXCM (FxcmBrokerageModel), OANDA (OandaBrokerageModel), Coinbase Pro (GDAXBrokerageinefinex), and Bitfinefinex? 

I see the data very well explained for AlphaStreams model here (https://www.quantconnect.com/docs/v2/alpha-streams/user-guides/alpha-fee-models) but it doesn't apply to the others.

 

Thanks!
