Hello,

I'm able to get to weekly SPX options using SPXW, and I can get to everything but weekly NDX options, but not the weekly options.  I'm trying to use this:

        self.index_symbol = self.AddIndex("NDX", Resolution.Minute).Symbol
        option = self.AddIndexOption("NDX")
        option.SetFilter(lambda universe: universe.IncludeWeeklys())

and I've tried:

        self.index_symbol = self.AddIndex("NDX", Resolution.Minute).Symbol
        option = self.AddIndexOption(self.index_symbol, "NQX")
        option.SetFilter(lambda universe: universe.IncludeWeeklys())
