Hi, while going through the <applied option> tutorial, I've found that the algortihms laid out different results when selecting option contracts by SetFilter method and OptionChainProvider. As far as I understand, they try to apply the same logic, thus I'm not getting hold of the difference in backtesting restuls.
Does anyone have clear explanation on this issue?
Any help would be greatly appreciated

Hi Jayjay,
When using SetFilter, we specify the filtering process for selecting the option contracts. The algorithm will automatically add and remove data subscriptions for those securities.
option.SetFilter(-3, +3, timedelta(0), timedelta(30))In contrast, when using the OptionChainProvider, data for the option contracts are not automatically (un)subscribed to. It simply returns all the option contracts symbols available for the given underlying. We need to add and remove the subscriptions manually.
contracts = self.OptionChainProvider.GetOptionContractList(self.equity.Symbol, slice.Time)To get the same results in a backtest, we would need to filter the contracts returned from the OptionChainProvider before selecting a contract to trade. See the attached backtest log for reference. Note that the SetFilter method results in 12 contracts being provided while the OptionChainProvider returns 800 contracts.
I recommend reviewing our documentation on options for more information.
Best,
Derek Melchin
