Is it possible to get an option's implied volatility in Python?
For example BasicTemplateOptionsHistoryAlgorithm.cs works fine in C#, printing out option Greeks and IV, but BasicTemplateOptionsHistoryAlgorithm.py is giving the following: Runtime Error: Python.Runtime.PythonException: KeyError : 'Level symbol must be same as name (None)'
It also looks like option.PriceModel cannot be set in the Python code.

Hi TurboDzyl, you can set the PriceModel by import the library
from QuantConnect.Securities.Option import OptionPriceModelsThe updated backtest code attached

Thanks Jing, Jared! Now it works as it should.
TurboDZyl
However the Greeks delta, gamma and theta are still showing 0, is there an equally simple solution for that?
TurboDZyl
Never mind, seems to be working now.
Am I correct that option data is only available in minute resolution? If so, is there a way to access the slice object on a larger resulotion (day or hour)? I've looked into consolidators but they seem to provide a bar object only.

Hi jared_broadl,
im having trouble getting the implied volatility of the next expiration ( it say the iv value is the same of the front, meaning in my code down self.first and self.second have the same value even though the should be slightly different
also it would be nice if option could have resolution of 1 hour to make backtest faster

equity = self.AddEquity("SPY", Resolution.Minute) option = self.AddOption("SPY", Resolution.Minute) self.symbol = option.Symbol option.PriceModel = OptionPriceModels.CrankNicolsonFD() option.SetFilter(self.UniverseFunc) #option.SetFilter(-2,2, timedelta(0), timedelta(180)) self.exp = 0 self.strike = 0 self.lors = None self.calls = None def UniverseFunc(self, universe): # include weekly contracts return universe.IncludeWeeklys().Expiration(TimeSpan.FromDays(2), TimeSpan.FromDays(40)).Strikes(-30,30) def OnData(self, data): #if not data.ContainsKey(self.vx1): # return if self.IsWarmingUp: return if self.day == self.Time.day: return if(data.HasData) : for kvp in data.OptionChains.Values: chains = kvp if kvp.Contracts.Count < 1: continue calls = list(filter(lambda x: x.Right == OptionRight.Call, chains)) puts = list(filter(lambda x: x.Right == OptionRight.Put, chains)) #self.underlying_price = self.Securities[self.spy].Price self.underlying_price = self.Securities[self.symbol].Price expiries = [i.Expiry for i in puts] strikes = [i.Strike for i in puts] if len(expiries) < 2: return strike = min(strikes, key=lambda x: abs(x-self.underlying_price * float(0.97) )) self.atm_call = [i for i in chains if i.Expiry == expiries[0] and i.Strike == strike] self.atm_put = [i for i in chains if i.Expiry ==expiries[0] and i.Strike ==strike] calls = [i for i in chains if i.Expiry == expiries[1] and i.Strike == strike] puts = [i for i in chains if i.Expiry ==expiries[1] and i.Strike ==strike] if len(self.atm_call) <1 or len(calls) < 1: return if calls[0].ImpliedVolatility == 0.0: return self.first = self.atm_call[0].ImpliedVolatility self.second = calls[0].ImpliedVolatilityÂ

Hi Lorrrr,
The IV of the two contracts are equal because the two contracts selected are actually the same contract. See the attached backtest for reference.
Best,
Derek Melchin

I got all 0 implied volatility and Greeks from the above code attached by Jing Wu. Any ideas? Thanks!
