HI, 

I installed LEAN CLI locally and tried to test Binance or Bitfinex paper trading, both of them cannot work. I already followed '

https://www.quantconnect.com/docs/v2/lean-cli/tutorials/live-trading/local-live-trading

' to setup lean.json correctly.

The script is simple like below:

class Test7(QCAlgorithm): def Initialize(self): self.AddCrypto("BTCUSD", Resolution.Minute, Market.Binance) def OnData(self, data): self.Debug(data.Time)

1. When I set live-paper data-queue-handler as 'BinanceBrokerage', the 'lean live test7 live-paper' output stop at as below, then just pause there

20210415 02:01:14.041 TRACE:: DataManager.AddSubscription(): Added BTCUSD,BTCUSD,Minute,TradeBar,Trade,Adjusted. Start: 4/15/2021 2:01:14 AM. End: 12/31/2050 5:00:00 AM

20210415 02:01:14.167 TRACE:: Debug: Paper Brokerage account base currency: USD
 

2. When I set live-paper data-queue-handler as 'BitfinexBrokerage' (I also update the scirpt to use Market.Bitfinex)

, the 'lean live test7 live-paper' output has error as below:

Error: Something went wrong while running 'test7' in the 'live-paper' environment,

 

Do we know why the local paper trading cannot work?

Thanks,
