Prevail,
You can play them for VEGA.... or Delta... or a combination of both.
My suggestion might be to sell the next month (Aug) option at where your downside target will be at expiration for that month. ... and purchase the following month puts two-four strikes out from that... A simple check of a risk profile graph at August expiration should give you a relative visual of the position)
You also want to place this trade at relatively low vols. So.. when VIX was at 13 a few days ago... the Aug 1225, Sept 1200p were my choice. (This choice may have been a little aggressive... but we have other diagonals lower... to unbrella the position).
You do NOT want to place this trade when VIX is relatively high.... this is trade is set up to LONG Vega. In Fact, this is a nice time to use Mo's & Mavericks suggestion and apply the short Calendar or Mav's Proprietary X-Tree strategy.
A few interesting notes.... as the VIX is rising here, the current diagonal is really interesting. (1200 Julyp/Aug 1175p) The July 1200p just isn't going up too much because of expiration, but the August 1175p is skyrocketing over the past few days.... this is the huge advantage over the credit spread. The value of the position has more than doubled in profit and has the potential as expiration to quadruple, depending on the VIX.
The disadvantage of the diagonal strategy is if the market moves up the entire month... VIX drops.... etc.... small but reasonable profit can be attained.
This is why I like placing the trade at low volatility levels... gives you small (2-5%) profits even if it moves away from you.
Now... here's an interesting play... MAVERICK would love this. We're looking to leave our 1175 Aug put in play and sell the back month SEPT puts against them with vix this high. (Short Calendar as Mo would explain). It's looking like a natural roll if VIX statys here at these levels for the next few days.
Hope this answers your questions...

Quote from Prevail:
Murray, I'm intrigued by the diagonals as, like you said, they benefit from rising vols. What criterion do you use to set them up?
Here is an example for discussion, what are your thoughts? All are welcome.
sell aug 1190 put: 9.6
buy sep 1150 put: 9.4
This is for a slight credit but I'm not looking for a large one. In the pic I've got the exit at the short strike.
