I have an algorithim that is working well. I tried changing from SPY to any other symbol, IWM, QQQ MSFT etc..and I'm getting This asset symbol ( ) was not found in your security list. Please add this security or check it exists before using it with 'Securities.ContainsKey(" ")'.
self.equity = ["SPY"]
self.AddEquity(self.equity[0], Resolution.Hour)
self.Securities[self.equity[0]].SetLeverage(1.5)
Not sure why changing SPY to any other symbol doesn't work.
Thanks

The reason for this could be because a string is being added into self.Securities as opposed to the Symbol object. Securities is a Dictionary<Symbol, Security> and in the line self.equity[0] is a string:
self.Securities[self.equity[0]].SetLeverage(1.5)If this is not the case, it would be helpful to attach a backtest so we can more accurately determine the problem.
