Option strategy - Long butterfly

Hi, testing Long Butterfly on SPY.

  • Buy 1 ATM Call
  • Buy 1 ATM Put
  • Sell 1 OTM Call to decrease cost of Long Call
  • Sell 1 OTM Put to decrease cost of Long Put

Overall, it works as expected, but I'm getting a lot of errors like this. Does anybody know why and how to fix it?1181 | 05:18:56: Backtest Handled Error: The security with symbol 'SPY 180202P00266000' is marked as non-tradable.

For OptionChainProvider, you need to wait until the next time step to receive the data after adding the contract with "AddOptionContract()". Therefore, the first time you place the order over the contract which was just added at the same time, there is the error message.

Hello Jing Wu, Im having the same issue than Artemiusgreat, what do you recommend to solve this?

 

Add the option contract earlier related to the signal?

Regards,

Nicolás

Hi all.

This Long Strangle tutorial is a good reference for implementing a Long Butterfly options strategy.  Sell instead of buy Out-The-Money (OTM) call and a put option:

### In TradeOptions()
# Sell OTM Call and OTM Put
self.Sell(self.call.Symbol ,1)
self.Sell(self.put.Symbol ,1)

Also, locate ATM put and call options and buy the contracts:

# Put
put = [i for i in chain if i.Right == OptionRight.Put]
putContracts = sorted(sorted(put, key=lambda x: x.Expiry, reverse=False),
key=lambda x: abs(x.UnderlyingLastPrice - x.Strike))
self.atmPut = putContracts[0]

# Call
call = [i for i in chain if i.Right == OptionRight.Call]
callContracts = sorted(sorted(call, key=lambda x: x.Expiry, reverse=False),
key=lambda x: abs(x.UnderlyingLastPrice - x.Strike))

self.atmCall = callContracts[0]

# Buy ATM Call contract and ATM Put contract
self.Buy(self.atmCall.Symbol ,1)
self.Buy(self.atmPut.Symbol ,1)

I've attached a backtest where I demonstrate how to extend the Long Strangle tutorial algorithm to implement a Long Butterfly options strategy using the code snippets above.
