is the difference between the 2 strikes… so for instance buy $37.50PUT, sell $40PUT… Margin required is $250 per contract.
Assuming the above is correct… How does the debit spread work? Assume instead of taking the above position as a credit put spread, I chose to do a Bull Call spread, buying the $37.50CALL and selling the $40 CALL. for a net debit of $1.45…
Is there a margin requirement in that case? and if yes what would it be?
Thank you all
