Mark,
I feel the real cost of not closing my diagonal.
rut gapped up and reversed. I wanted to close my long call but rejected because of the margin. I wanted to open another short call to hedge against it, and it was rejected too. I called the option desk, but I had been on hold for 30 min.
I tried to sell a naked call using TOS but failed because not enough margin.
Theta is working against me too! What should I do?
Quote from riskarb:
I actually like the position, in hindsight. But no, I don't buy vol into earnings.
Quote from optioncoach:
Well this was a little position to test something, but in a bigger sense I am testing using the Cross Flys on the SPX and the initial modelling looks promising. Nice R/R with little or no haircut and lots of room to select strikes...

Riskarb,
Assuming you wanted to play a large move in GOOG as Coach did, how would you have made that trade?

Quote from dagnyt:
Ouch. Sorry to hear.
Consider another broker, or talking seriously to TOS.
IB released all my margin from Oct index shorts this morning, at the opening of the market. Thus, I was able to sell any leftover positions.
You should be able to do that also. If not, closing Thurs afternoon becomes mandatory.
Best of luck next time.
Mark
Quote from riskarb:
Sure, but a loss at the mean of the implied distro, which can become significant with a drop in vols. I don't understand the shift in methodology from short gamma to long gamma/vega. You went from selling synthetic barrier options to buying duration backspreads.

here you go.

Short calendar on the call side + short calendar on the put side. Long gamma, short vega. Very muted risk if goog opened flat due to vega gains, and nice reward if goog moves as it did due to your gammas. Much better bet than a long backspread ahead of vol crush. Just my 2 cents.
