Since I didn't close my 820 call when I covered my 810 short so it didn't change my margin requirement. I opened this account with around 30K. The current margin requirement is still 30K. [edit] I also have my dec 840 call from the long leg of the diagonal. The short is partially hedged by both nov 820 call and dec 840 call.
The short legs of the initial DDs were too far from the spot. It didn't give me a good return on the margin as compared to verticals.
covered jan 690/nov730 put @ credit of 3.7 a gain of 1.1 for the put diagonal, but a loss of 0.35 in the call diagonal, so a net profit of 0.75 for a margin of 40. Less than 2% on ROM. I still own the dec 840 call, but it worths nothing now. DD is a bet on vega. Since IV is low, and so the return is basically due to the faster time decay of the front month compared to back month. I closed it this morning because I wanted to have the margin for hedging if rut goes near 780.
closed jan 840 @0.25 x 3 My nov 780 is naked in my opinion, but the margin is highly reduced because of the nov 820 which is worthless now. My whole trading style is based on adaptive leveraging, a method to get the optimal leverage.
Closed nov 780 @10.7 x 3 The naked call cost me a lot of money. Didn't realize the skew hurts the naked ITM options badly. I have to take it into account in the future for computing risk. Couldn't believe the portfolio can go from +5% return to -10% in a day.
