Quote from spindr0:
Out of sight risk for a vertical spread? If the reward of a vertical is 100%, it means that the premium is 1/2 the difference of the strikes. It doesn't matter if it's a credit spread or the synthetic put spread. The margin and the reward are the same.
1 - You're right.
2 - Obvious fact now that you pointed it out, but on credit spreads, not something I ever thought about. Interesting, actually.
