I am working on a simple crypto algorithm that works, but the backtest results do not incorporate fees from IBKR. I want to include IBKR's fee structure and trade execution for this algo, but when I run the algo, I get the error that Crypto is supported. I wondered if I did not understand something or if there wasn't support for the IBKR broker model and crypto. Here is my algorithm with the ibkr lines commented out:

from AlgorithmImports import *

class CryptoMomentumStrategy(QCAlgorithm):
def Initialize(self):
self.SetStartDate(2019, 1, 1)
self.SetEndDate(2024, 1, 1)
self.SetCash(1_000_000)
# self.set_brokerage_model(BrokerageName.INTERACTIVE_BROKERS_BROKERAGE, AccountType.CASH)


# Add BTCUSD crypto asset
self.btc = self.AddCrypto("BTCUSD", Resolution.Hour, Market.GDAX).Symbol


# Set the fee model for Interactive Brokers
# self.Securities[self.btc].SetFeeModel(InteractiveBrokersFeeModel())


self.lookback = 20 # Lookback period for momentum calculation
self.momentum = None


def OnData(self, data):
if not data.Bars.ContainsKey(self.btc):
return


# Fetch historical data for momentum calculation
history = self.History(self.btc, self.lookback, Resolution.Daily)
if len(history) < self.lookback:
return


# Calculate momentum as the percentage price change over the lookback period
start_price = history["close"].iloc[0]
end_price = history["close"].iloc[-1]
self.momentum = (end_price - start_price) / start_price


# Trading logic based on momentum
if self.momentum > 0 and not self.Portfolio[self.btc].Invested:
self.SetHoldings(self.btc, 1.0) # Go long on positive momentum
elif self.momentum < 0 and self.Portfolio[self.btc].Invested:
self.Liquidate(self.btc) # Exit position on negative momentum
