How easier to manage short leg?Quote from rallymode:
So that you are short downside gamma i would think. Easier to manage the short leg and stay close to neutrality vs had you sold it OTM where any vega gains will not be enough to offset your -gammas, especially true on the call side. I'd be surprised if anyone is making money on long call diagonals(short strike first) the last 2 months.

If crash through short strike will end up further on left side of put calendar(loss) on atm than otm. I am referring to P/L diagram.
Got to plug all this into option simulator. I miss my old TOS acct from 2 yrs ago. Still got that stupid monkey somewhere. Can't find similar function on IB. Need to either open small acct at TOS or get some software. Just don't feel like forking over 3K+ to OptionVue. Might need to ask the monkey.
Quote from spreadn00b:
I'm in the same boat. Have an IB acct, no real interest in a ToS account except for the software and forking over 3K is a bit much at this stage in the game for me. Maybe after I make my first 10 million, then I'll consider it.
Maybe I will open a ToS acct and let it sit there, what's the minimum?
Quote from riskarb:
The best time spreader I know would buy huge numbers [10k cars +] of otm put time spreads [same-strike] and get neutral [d] based upon a 7 day forward delta with index futures. IIRC, he made > $10mm one year [2001?] from a retail account. He never held a spread longer than 15 trading days. [/B]

Thanks, risk:
I've wondered about this part. Many of Murray's posts mention how the debit on these spreads tends to stay fairly constant over a fairly long period of time (relative to verticals) and I've noticed myself that this is the case. Why take on more time than necessary to achieve a goal. Two weeks sounds good. Maybe I'll look at a diagonal tomorrow.
Quote from ryank:
If I'm following you correctly, place a DD at 1SD and the price stays relatively constant until you start getting close to expiration. I did a quick model of this in TOS based on what it cost me for my DD I put on a few weeks ago vs what a DD would cost today at 1SD from the market. The cost is nearly identicle BUT the short strikes are much closer to the market now than they were then.
