Obviously you monitor PoT (how do you calculate this?). What has to happen to "make the final decision" of closing a spread or letting it go on and expire?. With spreads 1 day to expiration, every metric is very "jumpy". How do you decide when/if to do the closing (bad) or let expire (good)?.
I covered this in the post at the top of page 20. If PoT is less than 10% (7% for those more cautions) I will let it expire. I make this decision between 30 and 45 minutes before trading closes. If the day starts out with PoT near my limit I will watch throughout the day. If the overnight futures show an adverse move, I will watch at opening of trading.
Howard I think OPTION COACH had mentioned it. IRON CONDORS really only work with reliability in a bull market, with VIX in his case below VIX 20 and in my estimation below VIX 22. When you are in a bull trend as you are now with VIX 15 your Iron condors should work well. But you are going to get hit and wipe out your account when the VIX rises to around VIX 26 and above. You can´t trade them all the time, and succeed. The risks grow exponentially as the VIX rises. These are just rule of thumb experiences. What this means in practice, the real world is that Iron Condors which are non-directional as you say, are of limited application. You don´t use them all the time. The majority of the time you play Vertical Credit Spreads in a directional play. Thus if you have to predict direction, then you might as well straight buy options which is safer.
Howard A little tidbit from one years experience but a lot of trades in weeklies compared to slower monthly trades. Thursday and Friday of expiration week, 3% deviation covers BEAR CALL SPREADS and 4% deviation covers Bull Put Spreads fine. So if your spreads on a Thursday outside of those deviations, you are probably safe to go to expiration.

I presume that you've back tested this system against some of the more notorious crashes, notably in the fall of 2008 and March 2009, when it would be necessary to stop out of the bull put spreads. What sort of results do you get for those periods? Did you use actual option prices at those times (with high IV and wide bid/ask spreads) or estimates?
