Quote from PatelAtWork:
What sorts of margin requirements are needed for writting naked puts/calls for say ER2?
IB says, for Short Naked put:
100% * option market value + maximum (((20% * (underlying market value) - out of the money amount), 10% * strike price, $2.50 * multiplier * number of contracts). 20% above is 15% for broad based index options. Short sale proceeds are applied to cash.
Same rules as cash for IRA Margin Accounts.
Can someone please explain the above to me? I mean if ER2 is being traded right now at 700, and I want to write 670P for July, which has premium of 7.10, what would be the margin requirement? Say I have 100K in my margin account with Option level 4 clearance, how many contracts of 670P can I write?
This is just hypothetical, I'm not really gonna do it, just need to understand it.
Thanks for all your help (or flame, if it should come my way ;-))
