Quote from jeffm:
As Mo's post points out, ES spread margin is better than SPX. How much better also depends on the width of the spread. A 5 pt ES spread will have margin similar to a 5 pt SPX spread (remember that you will need 2 ES contracts to equal 1 SPX). A 20 point spread will be quite a bit higher with SPX vs ES. A 100 point spread would need huge margin on SPX, but not a big deal at all on ES. Taken to the logical conclusion...selling naked on SPX is a no-go, but as has been discussed, selling naked on futures is not a problem.
With SPX, Uncle Sam and Reg-T hold your hand to make sure you don't overleverage. SPAN is like Earl Campbell with a tear-away jersey
Neither one will help you if you walk off a cliff. SPAN just lets you get to the edge faster. Choose your path wisely![]()
all perfectly pointed out. it is so easy to get greedy and walk off that cliff. the only thing i can say , is; i have been writing options for years. i intend on being a survivor.
such an evolution though, i never considered indexes, future options , etc until coaches thread.
