Quote from JackR:
Perhaps someone could answer this hypothetical:
I have an IB IRA account. I am long 10 contracts of GOOG at 300 (1000 shares).
I have $1K in cash in the account and no other equity.
I elect to exercise the options to buy the 1000 shares of GOOG at 300 because I plan to immediately sell the 1000 shares at 304. (Forget that I could probably sell the options for much more than a $4 premium).
Would IB allow me to exercise the options and generate a $299K debit in a cash account?
If not, why not?
If not, and I have the right to tell IB not to execise upon expiration, don't they have the same obligation to act in a reasonable manner and decline the exercise on my behalf.
maybe you should call or email ib and get the correct answer.
