Hi, I am just messing around with the long straddle tutorial algorithim and I am a bit confused.
Once a call is executed, then that means I own some of the stock right? How do I sell the stock right away and restart the straddle strategy?
Sorry if this is a stupid question :/

Yes please. I didnt even figure out how to access optionchains in the slice object parameter of onData function yet. It seems to be null. Please link the tutorial.

Hi Kevin,
Yes you could definitely sell right after each buy. It will just make the algorithm not profitable at all. Simple put a self.Sell() after each self.Buy() statement would achieve the strategy you mentioned. Here is a code snippet with this modification:
from datetime import timedelta class BullCallSpreadAlgorithm(QCAlgorithm): def Initialize(self): self.SetStartDate(2017, 4, 1) self.SetEndDate(2017, 6, 30) self.SetCash(1000000) equity = self.AddEquity("GOOG", Resolution.Minute) option = self.AddOption("GOOG", Resolution.Minute) self.symbol = option.Symbol # set our strike/expiry filter for this option chain option.SetFilter(-6, 6, timedelta(30), timedelta(60)) # use the underlying equity GOOG as the benchmark self.SetBenchmark(equity.Symbol) def OnData(self,slice): for i in slice.OptionChains: chains = i.Value if not self.Portfolio.Invested: self.TradeOptions(chains) def TradeOptions(self,chains): # sorted the optionchain by expiration date and choose the furthest date expiry = sorted(chains,key = lambda x: x.Expiry, reverse=True)[0].Expiry # filter the call and put contract call = [i for i in chains if i.Expiry == expiry and i.Right == OptionRight.Call] put = [i for i in chains if i.Expiry == expiry and i.Right == OptionRight.Put] # sorted the contracts according to their strike prices call_contracts = sorted(call,key = lambda x: x.Strike) if len(call_contracts) == 0: return self.call = call_contracts[0] for i in put: if i.Strike == self.call.Strike: self.put = i self.Buy(self.call.Symbol, 1) self.Buy(self.put.Symbol ,1) self.Sell(self.call.Symbol, 1) self.Sell(self.put.Symbol ,1) def OnOrderEvent(self, orderEvent): self.Log(str(orderEvent))@Rupert I believe this is the tutorial example that Kevin was working on.
Hope it helps!
