Hello everyone,
I'd like to remove some options from my universe and add others. I'd tried using self.RemoveSecurity(security) but when I log the active securities afterwards, nothing has changed. Did I do something wrong?
Best regards,
Christian

Hey Christian,
There are two things to watch out for.
First, when we remove a security from our universe using RemoveSecurity(symbol), it takes at least one time step for it to take effect. So instead of using one scheduled event to both remove and check, we should remove securities and check our list in different scheduled events.
Second, when we want to remove options from our universe, we need to remove the symbol of the option chain.
option = self.AddOption(ticker, Resolution.Minute) self.RemoveSecurities(option.Symbol)I created an example based on your code to demonstrate this.
