Erm, this is a rather funny statement, methinks... Unless I am getting all dazed (it's late) and confused, isn't what you describe precisely an iron condor?
In general, the simplest fire-'n-forget structure would be a fly where you try to pin the strike. Iron condors and other variations on this theme are all the based on a similar idea, where you'd do the trade if your view is that the distribution implied by the mkt price of the structure doesn't have enough mass in a particular area in the middle (and too much mass in the wings). These are all variations of a short vol trades. Problem is twofold: a) there's a directional component, as sle says; b) viability of these trades depends on how the mkt prices various strikes.
My Z$2c. I'm sure the experts' insight is far superior to mine in this.
Ah, maybe I forgot to explain properly - I mean you would exit the put spread near the bottom of the range, before you put on your bull call spread. Essentially you'd be making bets on moderate falls when the range is at its highs, and vice versa when at its lows. The spread would be used to keep the vol exposure moderate, since you expect it to decline.
I have tried with butterflies, but the problem is that your results at expiry depend so much on luck, what if its at the bottom of the range at expiry? You would be right on the range, right on falling vol, and still have a bad result. If you use iron condors wide enough to avoid this risk, your return kinda sucks. Plus you have those wonderful 4 commissions and bid-offer spreads to pay
At least with the vertical spreads, it is fairly obvious what to do. I'm fine with taking a directional view, since I would only put these on when I think I can anticipate it to some extent.
Reason I don't want to gamma hedge is I would only put on short vol positions when I'm pretty confident about a range - if I'm wrong then the other spread leg will cap the loss.
Someone might suggest just using outrights. The problem here is your outlier risk in case of some news event; and the risk of being faked out if there is a false breakout for a day or two. Trading ranges are notorious for triggering stops at either end, then reversing a few days later to re-enter the range. Having on a limited-risk options position lets you sit through such noise with impunity.
Disclaimer, I am a total noob at trading volatility, so I am probably missing some fairly obvious stuff here.
