Why does simulation end on Dec 22, 2021 instead of current date?

I am trying to plot an asset from 8/15/21 to the present date - but the last date I see on the chart is Dec 22, 2021 (instead of the current date).

Here is the code:

class VirtualFluorescentYellowJackal(QCAlgorithm):
   def Initialize(self):
       self.SetStartDate(2021, 8, 15)  # Set Start Date
       self.SetEndDate(2022, 2, 16)  # Set End Date
       self.SetCash(100000)  # Set Strategy Cash
       self.tqqq = self.AddEquity("TQQQ", Resolution.Hour)
       # create 21 day EMA of TQQQ
       self.ema = self.EMA("TQQQ", 21 * 8, Resolution.Hour);
       self.SetWarmUp(21)
       # Defaults to Equity market
       self.SetBenchmark("TQQQ")
       
   def OnData(self, data):
       if self.IsWarmingUp:
           return
           
       self.Plot("Data Chart", "Asset Price", self.Securities["TQQQ"].Open)
       self.Plot("Data Chart", "EMA", self.ema.Current.Value)

And here is the chart which ends on Dec 22, 2021 instead of today:

Why isn't the chart plotting extend to the current day?
