Financing: how to sell boxes properly?

Last time in June I rolled the SPX box the cost is ~1.63% + commission.
0 margin for IBHK

No looks good to me

But you do have portfolio margin account correct? Because otherwise the whole 50k would be going to margin for the box itself.

Also, make sure you do this with the correct options. Because with some options on futures, there's actually no money debited/credited when doing the trade. Instead those are based on marked-to-market and you pay the difference on a daily basis (just like futures). That would mean this idea wouldn't work...

Did you figure out how much margin required for box that gives 50k credit?
