Hi,

I cannot get the prices for the ticker "QQQ".

Prices for all other tickers work fine.

 

Here's the code:

 

class NadionQuantumGearbox(QCAlgorithm):

    def Initialize(self):
        self.SetStartDate(2019, 9, 12)  # Set Start Date
        self.SetCash(100000)  # Set Strategy Cash
        self.AddEquity("SPY", Resolution.Minute)
        self.AddEquity("QQQ", Resolution.Daily)


    def OnData(self, data):

        h = self.History(self.Symbol('SPY'), 252 * 3, Resolution.Daily).iloc[:]['close']
        
        h2 = self.History(self.Symbol('QQQ'), 252 * 3, Resolution.Daily).iloc[:]['close']
        assert(0)
