Hi
I'm planning to backtest on Tether from bitfinex, which the data library doc has its symbol as "USTUSD". Yet I received the following error:
During the algorithm initialization, the following exception has occurred: ArgumentException : Symbol can't be found in the Symbol Properties Database: USTUSD
at QuantConnect.Securities.SecurityService.CreateSecurity(Symbol symbol, List`1 subscriptionDataConfigList, Decimal leverage, Boolean addToSymbolCache) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Securities/SecurityService.cs:line 81

I solved the problem. The actual symbol is "USDTUSD", not the one on doc.Â

Hi Louis,
It's normally not necessary to subscribe to USDTUSD since it's a stablecoin. Refer to this PR.
Best,
