RetiredMM I have another question about closing a leg in CS. If you purchase a call and the stock moves up so you sell a higher strike price to get a credit, does it need to be closed by you before expiration even if otm? If you pay an overall debit for the CS can you let it expire for the premium of the sold calls? Is there a chance the purchaser will exercise? Thanks again.
