Picking up pennies in front of steam rollers. That is the specific criticism of your strategy.
You are systematically selling options, without systematically viewing them as overpriced. The premium you receive from your short options by definition will not cover your losses in the long run, once bid/offer spread, slippage, risk of market gaps and commission etc. is factored in your strategy is guaranteed to lose.
Now, as the steamroller analogy is meant to show, people employing these strategies often have good results, they make money - for a time. Then comes the day that they lose all they have made and more - that is not a dramatized statement, it is a statement of fact.
As I understand it the main tenets of your strategy are some form of money management - this is irrelevant, you cannot money manage away the risks you are exposing yourself to. And, mainly I think, a "probability of touching" measure that is supposed to ensure you set the condor wide enough that you hardly ever get into trouble. Well, and this is fact based, the problem is that the market already has "probability of touching" factored in by way of lower premiums for further OTM options. This means that you are at best (at the very best) merely playing a 'fair' game - you widen the condor, you receive less premium, a smaller future loser wipes that profit out. You tighten the strikes, get more premium but have more losers.
You have said that you don't think 9 months of results is enough data, but then you bandy your account balance around as if that is proof it is a good strategy! The conflict present in that behaviour is staggering. You could carry on like this for several years before you really blew out. I don't care if you do all your money, I kind of hope you do as maybe then you'll realise what is going on - my only motivation for posting this is intellectual, as in I have some kind of need to step in and correct blatant and dangerous errors, as I think people like MG and Arab do as well.
That is all. Cheers.
