stupid question
but if i see a credit spread for 90$ and i need to pay 10$ to pay it so it means my whole risk is 10$ that's my loss
but does it mean i can take the 90$ to buy lunch till expiry then it will expire with -10$?
I'm confused. You don't pay for credit spreads, they are initiated @ a credit, which you sold.
Debit spreads are paid for, and the debit paid is your max risk.
Also lets say you sold a credit spread, I don't think you can collateralize the premium sold. Theoretically you can? Someone correct me.
Box arbitrage..
