Algorithm Example

class CBOEDataAlgorithmAlgorithm(QCAlgorithm):

    def Initialize(self) -> None:

        self.spy = self.AddEquity("SPY", Resolution.Daily).Symbol

        # Define the symbol and "type" of our generic data
        self.vix = self.AddData(CBOE, 'VIX', Resolution.Daily).Symbol
        self.vxv = self.AddData(CBOE, 'VIX3M', Resolution.Daily).Symbol
        # Set up default Indicators, these are just 'identities' of the closing price
        self.vix_sma = self.SMA(self.vix, 1, Resolution.Daily)
        self.vxv_sma = self.SMA(self.vxv, 1, Resolution.Daily)
        # This will create a new indicator whose value is smaVXV / smaVIX
        self.ratio = IndicatorExtensions.Over(self.vxv_sma, self.vix_sma)
        # Plot indicators each time they update using the PlotIndicator function
        self.PlotIndicator("Ratio", self.ratio)
        self.PlotIndicator("Data", self.vix_sma, self.vxv_sma)

        history = self.History(CBOE, self.vix, 60, Resolution.Daily)
        self.Debug(f"We got {len(history.index)} items from our history request");
    def OnData(self, slice: Slice) -> None:
        # Wait for all indicators to fully initialize
        if not (self.vix_sma.IsReady and self.vxv_sma.IsReady and self.ratio.IsReady): return
        if not self.Portfolio.Invested and self.ratio.Current.Value > 1:
