I'm trying to learn how to do the most basic python start on quantconnect, but I keep running into what seems to be a very basic error. Could anyone give a newcomer some support?

Thank you.

Code:

class UncoupledParticleEngine(QCAlgorithm): def Initialize(self): self.SetStartDate(2015, 1, 1) # Set Start Date self.SetCash(100000) # Set Strategy Cash self.AddEquity("SPY", Resolution.Minute) # self.AddEquity("SPY", Resolution.Minute) self.rsi = self.RSI("SPY", 10, MovingAverageType.Simple, Resolution.Daily) # set a warm-up period to initialize the indicator self.SetWarmUp(timedelta(20)) # Warm-up the indicator with bar count # self.SetWarmUp(10, Resolution.Daily) def OnData(self, data): ## You can access the TradeBar dictionary in the slice object and then subset by symbol ## to get the TradeBar for SPY tradeBars = data.Bars spyTradeBar = tradeBars['SPY'] spyOpen = spyTradeBar.Open ## Open price spyClose = spyTradeBar.Close ## Close price # if not self.Portfolio.Invested: # self.SetHoldings("SPY", 1)

Error:
