Trying to close an option based on the underlyinh price. I have a code here, but I don't think that this is the right way to do it:
if (self.Securities[self.equity_symbol].Price < self.option_symbol.UnderlyingLastPrice):
self._buyTicket = self.Buy(self.option_symbol.Symbol, 10)
I want the code above to be always true, not only in one day. It is similar to creating an order event, but the condition is on the underlying price instead of the option price itself.
Thanks

Hi Nick,
If by 'to always be true' you mean that this condition will be evaluated for every contract, then I think the best way to do this would be to write a function which takes an option contract and a Trade Bar as arguments and then compares the underlying last price to the current price of the equity. Then, if the condition is matched as the algorithm loops through the current contracts in the Universe, you can place the Buy order inside the function. I've attached a backtest that implements a simple version of this.
However, self.Securities[self.equity_symbol].Price and self.option_symbol.UnderlyingLastPrice will return the same value, so the condition to check for inequality will always return False. If you attach your code or elaborate more of what exactly you're trying to accomplish, that would help me to make suggestions or provide solutions to any issues you are encountering.

Hi Jack,
Thanks for your code. I have modified it to illustrate my question better. I have bought a put contract and want to sell it at some point in future when the underlying_price is less than the underlying_price when the option was originally bought.
I also have another concern. In this example I have simplified the condition, but what I really want to do is to sell the option after some profit or loss, but I am not sure how to calculate profit of an option strategy.

Hi Nick,
Depending on your options strategy, you can calculate profit in different ways.
If you want to sell the option before expiration, then you can calculate profit using the UnrealizedProfit attribute of a security.
self.Portfolio[optionContract.Symbol].UnrealizedProfitIf you plan to exercise your options/let them expire, then you would want to calculate the exercise value using something like the following:
def CalculateExerciseProfit(self, optionContract, dataTime): if optionContract.Expiry == dataTime: strike = optionContract.Strike underlying = optionContract.UnderlyingLastPrice quantity = self.Portfolio[optionContract.Symbol].Quantity ## Options contracts are for 100 shares, so multiply by 100 ## and the number of contracts that will be exercised if (optionContract.Right == OptionRight.Call): exerciseProfit = (underlying - strike) * 100 * quantity if (optionContract.Right == OptionRight.Put): exerciseProfit = (strike - underlying) * 100 * quantity return exerciseProfitThis value could be calculated anytime but is only relevant when the options expire. It is sub-optimal to exercise an option before expiration unless it is an American option whose underlying pays a dividend.
