I often hear Jim Rogers talk about holding commodities, "the real stuff". I'm assuming he means futures and continually rolling them over for the long term. What does an example of that look like? What happens if you forget about expiration? I use thinkorswim as my broker. If you hold a future overnight, the required margin goes up substantially: https://www.thinkorswim.com/tos/displayPage.tos?webpage=servicesOrderTypes&displayFormat=hide#. I never see anyone talk about this. I often see you need a min of $20k and no more than 2 contracts for e-minis for example. Does this also consider the overnight margin increase?
