Would this error be due to a data problem or a code problem?
I cant seem to attatch a backtest here is the code snippet
class SupportAndResistance(QCAlgorithm):
UnderlyingTicker = 'SPY'
openingBar = None;

self.SetStartDate(2020, 1, 1)
self.SetEndDate(2020,1,31)

equity = self.AddEquity(self.UnderlyingTicker, Resolution.Minute)
equity.SetDataNormalizationMode(DataNormalizationMode.Raw)
option = self.AddOption(self.UnderlyingTicker)
self.Consolidate(self.UnderlyingTicker, timedelta(1), self.OnDataConsolidated)
self.option_symbol = option.Symbol
# set our strike/expiry filter for this option chain
option.SetFilter(lambda u: u.IncludeWeeklys().Strikes(0, 10).Expiration(timedelta(0), timedelta(7)))
# option.SetFilter(lambda u: (u.Strikes(-2, +2)
# # Expiration method accepts TimeSpan objects or integer for days.
# # The following statements yield the same filtering criteria
# .Expiration(0, 180)))

# self.Schedule.On(self.DateRules.EveryDay(self.UnderlyingTicker), self.TimeRules.At(13, 30), self.ClosePositions)
# use the underlying equity as the benchmark
self.SetBenchmark(equity.Symbol)

Hi Tom,
Data for a symbol may sometimes be missing for a particular time slice. In order to account for this, we should check whether that data exists in the slice before attempting to access it.
if not slice.ContainsKey(self.UnderlyingTicker): self.Debug(f"NO {self.UnderlyingTicker} data on {self.Time}") return
