Implied Volatility

Introduction

Implied Volatility indicator that calculate the IV of an option using Black-Scholes Model

To view the implementation of this indicator, see the LEAN GitHub repository.

Using IV Indicator

To create an automatic indicators for ImpliedVolatility, call the IV helper method from the QCAlgorithm class. The IV method creates a ImpliedVolatility object, hooks it up for automatic updates, and returns it so you can used it in your algorithm. In most cases, you should call the helper method in the Initializeinitialize method.

public class ImpliedVolatilityAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private Symbol _option, _mirrorOption;
    private ImpliedVolatility _iv;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _option = QuantConnect.Symbol.CreateOption("SPY", Market.USA, OptionStyle.American, OptionRight.Put, 450m, new DateTime(2023, 12, 22));
        AddOptionContract(_option, Resolution.Daily);
        _mirrorOption = QuantConnect.Symbol.CreateOption("SPY", Market.USA, OptionStyle.American, OptionRight.Call, 450m, new DateTime(2023, 12, 22));
        AddOptionContract(_mirrorOption, Resolution.Daily);
        _iv = IV(_option, _mirrorOption);
    }

    public override void OnData(Slice data)
    {
        if (_iv.IsReady)
        {
            // The current value of _iv is represented by itself (_iv)
            // or _iv.Current.Value
            Plot("ImpliedVolatility", "iv", _iv);

The following reference table describes the IV method:

iv(symbol, mirror_option=None, risk_free_rate=None, dividend_yield=None, option_model=None, resolution=None)[source]

Creates a new ImpliedVolatility indicator for the symbol The indicator will be automatically updated on the symbol's subscription resolution

Parameters:
  • symbol (Symbol) — The option symbol whose values we want as an indicator
  • mirror_option (Symbol, optional) — The mirror option contract used for parity type calculation
  • risk_free_rate (float, optional) — The risk free rate
  • dividend_yield (float, optional) — The dividend yield
  • option_model (OptionPricingModelType, optional) — The option pricing model used to estimate IV
  • resolution (Resolution, optional) — The desired resolution of the data
Returns:

A new ImpliedVolatility indicator for the specified symbol

Return type:

ImpliedVolatility

IV(symbol, mirrorOption=None, riskFreeRate=None, dividendYield=None, optionModel=None, resolution=None)[source]

Creates a new ImpliedVolatility indicator for the symbol The indicator will be automatically updated on the symbol's subscription resolution

Parameters:
  • symbol (Symbol) — The option symbol whose values we want as an indicator
  • mirrorOption (Symbol, optional) — The mirror option contract used for parity type calculation
  • riskFreeRate (decimal, optional) — The risk free rate
  • dividendYield (decimal, optional) — The dividend yield
  • optionModel (OptionPricingModelType, optional) — The option pricing model used to estimate IV
  • resolution (Resolution, optional) — The desired resolution of the data
Returns:

A new ImpliedVolatility indicator for the specified symbol

Return type:

ImpliedVolatility

If you don't provide a resolution, it defaults to the security resolution. If you provide a resolution, it must be greater than or equal to the resolution of the security. For instance, if you subscribe to hourly data for a security, you should update its indicator with data that spans 1 hour or longer.

For more information about the selector argument, see Alternative Price Fields.

For more information about plotting indicators, see Plotting Indicators.

You can manually create a ImpliedVolatility indicator, so it doesn't automatically update. Manual indicators let you update their values with any data you choose.

Updating your indicator manually enables you to control when the indicator is updated and what data you use to update it. To manually update the indicator, call the Updateupdate method with time/number pair or an IndicatorDataPoint. The indicator will only be ready after you prime it with enough data.

Indicator History

To get the historical data of the ImpliedVolatility indicator, call the IndicatorHistoryself.indicator_history method. This method resets your indicator, makes a history request, and updates the indicator with the historical data. Just like with regular history requests, the IndicatorHistoryindicator_history method supports time periods based on a trailing number of bars, a trailing period of time, or a defined period of time. If you don't provide a resolution argument, it defaults to match the resolution of the security subscription.

        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._option = Symbol.create_option("SPY", Market.USA, OptionStyle.AMERICAN, OptionRight.PUT, 225, datetime(2024, 7, 12))
        self.add_option_contract(self._option, Resolution.DAILY)
        self._mirror_option = Symbol.create_option("SPY", Market.USA, OptionStyle.AMERICAN, OptionRight.CALL, 225, datetime(2024, 7, 12))
        self.add_option_contract(self._mirror_option, Resolution.DAILY)

To make the IndicatorHistoryindicator_history method update the indicator with an alternative price field instead of the close (or mid-price) of each bar, pass a selector argument.

var indicatorHistory = IndicatorHistory(iv, 100, Resolution.Minute, (bar) => ((TradeBar)bar).High);
indicator_history = self.indicator_history(iv, 100, Resolution.MINUTE, lambda bar: bar.high)
indicator_history_df = indicator_history.data_frame

If you already have a list of Slice objects, you can pass them to the IndicatorHistoryindicator_history method to avoid the internal history request.

var history = History(new[] { _symbol, _option, _mirrorOption }, 100, Resolution.Minute);
var historyIndicatorHistory = IndicatorHistory(iv, history);

To access the properties of the indicator history, invoke the property of each IndicatorDataPoint object.index the DataFrame with the property name.

var optionsymbol = indicatorHistory.Select(x => ((dynamic)x).OptionSymbol).ToList();
var riskfreerate = indicatorHistory.Select(x => ((dynamic)x).RiskFreeRate).ToList();
var dividendyield = indicatorHistory.Select(x => ((dynamic)x).DividendYield).ToList();
var price = indicatorHistory.Select(x => ((dynamic)x).Price).ToList();
var oppositeprice = indicatorHistory.Select(x => ((dynamic)x).OppositePrice).ToList();
var underlyingprice = indicatorHistory.Select(x => ((dynamic)x).UnderlyingPrice).ToList();

// Alternative way
// var optionsymbol = indicatorHistory.Select(x => x["optionsymbol"]).ToList();
// var riskfreerate = indicatorHistory.Select(x => x["riskfreerate"]).ToList();
// var dividendyield = indicatorHistory.Select(x => x["dividendyield"]).ToList();
// var price = indicatorHistory.Select(x => x["price"]).ToList();
// var oppositeprice = indicatorHistory.Select(x => x["oppositeprice"]).ToList();
// var underlyingprice = indicatorHistory.Select(x => x["underlyingprice"]).ToList();

option_symbol = indicator_history_df["option_symbol"]
risk_free_rate = indicator_history_df["risk_free_rate"]
dividend_yield = indicator_history_df["dividend_yield"]
price = indicator_history_df["price"]
opposite_price = indicator_history_df["opposite_price"]
underlying_price = indicator_history_df["underlying_price"]

# Alternative way
# option_symbol = indicator_history_df.option_symbol
# risk_free_rate = indicator_history_df.risk_free_rate
# dividend_yield = indicator_history_df.dividend_yield
# price = indicator_history_df.price
# opposite_price = indicator_history_df.opposite_price
# underlying_price = indicator_history_df.underlying_price
