About US Equity Options

The US Equity Options data by AlgoSeek provides Option data, including prices, strikes, expires, implied volatility, and Greeks. The data covers 4,000 Symbols, starts in January 2012, and is delivered on a minute frequency. This dataset is created by monitoring Options Price Reporting Authority (OPRA) data feed, which consolidates last sale and quotation information originating from the national securities exchanges that have been approved by the Securities and Exchange Commission.

This dataset depends on the US Equity Security Master dataset because the US Equity Security Master dataset contains information on splits, dividends, and symbol changes of the underlying security.

class USEquityOptionsDataAlgorithm(QCAlgorithm):

    def Initialize(self) -> None:
        self.SetStartDate(2020, 6, 1)
        self.SetEndDate(2020, 8, 1)

        self.underlying = self.AddEquity("GOOG").Symbol
        option = self.AddOption("GOOG")
        self.option_symbol = option.Symbol

        option.SetFilter(-2, +2, 0, 7)
        self.contract = None

        if self.contract is not None and self.Portfolio[self.contract.Symbol].Invested:

        chain = slice.OptionChains.get(self.option_symbol)

            self.MarketOrder(self.contract.Symbol, 1)
    def OnSecuritiesChanged(self, changes: SecurityChanges) -> None:
        for security in changes.AddedSecurities:
            # Historical data
            history = self.History(security.Symbol, 10, Resolution.Minute)
            self.Debug(f"We got {len(history)} from our history request for {security.Symbol}")
