My strategy has evolved considerably in the last year. It started from a reading of Jon Schiller's book "100% Return on Options Strategy" (worth reading). He noted that one could predictably define the range the OEX typically moves in an option month. He did this by keeping track of the last thirteen months of OEX closing data and calculating the cumulative point move to the upside and the cumulative point move to the downside. He then calculated the second standard deviation of the average point moves for the last thirteen months and these numbers are added and subtracted from the closing value of the OEX after options expiration. These numbers became his targets for opening credit spreads. He suggested you open two five point spreads, one call and one put at these targets at market close on the first day of the option month. This worked OK and gave a predictable 7% return. But as I watched the spread values during the month I noticed that I could do much better than 7% just by having patience enough for the OEX to approach these target prices. His method also tended to put me too close to the market and I had to close several trades at breakeven or a loss. So I started looking at the percent change I could expect from each day of an option trading day to the close of the option month. (It is very interesting to view trading months by option months rather than calendar months, which is what I did). I took the last ten years worth of data to begin with and averaged out all the percent changes from day x to close of option month. I then calculated out the third standard deviation of each of these numbers and have created a list of factors, both a call factor and a put factor. So given any day of an option month (trading days remaining) I can multiply the OEX closing value and more or less determine "the gutters" of a "normal" trading month. I then wait for the OEX to approach either "gutter" and then open a credit spread with good premium. If all works well, the OEX should move away from this position towards the other "gutter", at which point I can close my original position and open another one. Again the same should happen. In June I got three trades in like this and acheived a 42% return on capital for the month. However, July was not a good month, I got greedy and played a defined target minus five points (725 call instead of 730 call). Well July made a new record % move, which my system does not take into account and never can, however record months are few and far between and a stop loss technique must be at the ready. Thought I was going to have to use one this month as my highest defined put target was a 660 put. My lowest defined call target in now a 710 call and so I am hoping the OEX will continue up next week and I will be able to close my first spread and open a second. That's the jist of it, it is a little more involed since I have a factor defined for every option trading day. I have back tested a simpler method for five years and it is 100% accurate for winning trades but only gives 10 tp 15% per month.
