    Hi. I am in a bit of a dilemma regarding margin calls on stock options vs. futures options.

    If I write uncovered puts on, let's say, shares of XOM and ES futures worth the same amount (max loss is the same), and the positions move against me, will I get a margin call on my XOM options FASTER than on the ES futures? The logic being that to deliver XOM shares I will need to post at least a 50% margin to buy them, while only around 13% to buy the ES futures (depending on the broker).

    Thanks in advance
