Rally,
I actually placed a Donna positions when I enterd the Call Side.
This means I legged into the put on the downside. But in general, as you pointed out, the Put side is difficult if not impossible to put on for EVEN.
The call side is tricky. As you pointed out, getting in for even or for a small credit and the appropriate distance is a matter of the current volatility skew. I have found that the OEX has been a better fill risk/reward than the SPX.... but that can change.
My goal is to ratio the upside for even or better, with littleo to know risk if the market takes off. This can be accomplished.
For example: Recently I bought 10 May 625c and sold 4 Apr 605c and then sold 6 addition April 625c. What is nice here... is the margin requirement is only for the 4 short positions sold at 605.
The positions risk graphs looks like an unbrella... which can be adjusted.
As coach pointed out.... in his positon, as the market moves up... to the short positions.... this is maximum profit... and you have break even potential beyond the short. I would certainly attempt to hold the positon to as close to expiraton as possible.... the preimium really bleeds out the last week... while the long has potential to increase in VEGA without the shorts having much effect.
In summary... the Diagonal... is a VEGA play... yet, gives you profit potential through large range.... and 'black swan' protection.

Quote from rallymode:
This started looking to me like it was too good to be true and as i know there are no free lunches i did further research to find the problem. Now it appears that getting a 30-35 point spread at a 10:5 long to short ratio is clearly an arbitrage. That is the only position that will give you profit at or beyond your long strike.
Sailing -> you say you have this position at breakeven:
10 May 1190 Puts
- 5 Apr 1225 Puts
Hold onto it cuz you CANNOT lose no matter where the market ends at APR expiration.
If you were to liquidate today even at the bid and ask you will make $.75 credit.
If i were to buy your position today and split the Bid/Ask, the best i can do is a debit of $1.3. I dont see how you placed that trade at breakeven two weeks ago. Could it be a typo and you meant 7 short puts instead of 5? Or maybe you have 10 shorts and 5 longs since the may 1190 put price is twice the 1225 put price.
The best i see possible is a 10:7 ratio on a 30-35 point spread and that will need adjustments with the SPX between your strikes.
Anyone else see the same thing?
PS If my math is off, excuse me, its kinda late and i should've had less coffeee today
