Please help try to clarify my question while I talk with my broker at the same time. It is concerning margin requirements for an options spread. If I sell a hypothetical 5 point wide option spread for 1 point, and the points are $100, should I be charged $500 collateral to hold the spread or $400? I believe it should be $400, since I'm taking in $100, and my max risk in the trade is only $400. Thoughts? Thanks.
