Quote from JSHINV:
This strategy you can win most of the time; but when you lose you can lose big. If you're making good money on selling wings, that means you are probably selling a number of contracts. Even if there is little time left to expiration and it moves way big against you, there can be a lot of negative gamma to cover. Having said that, you can still be a net seller by doing a ratio write, which will mitigate the unlimited risk somewhat. Or you can sell a credit spread - which has a defined risk. Now, I used to say I would never sell naked. There may be situations where I'd do it (I haven't for years). But, to make a living selling OTM options, scares the heck out of me. This forum and the well respected books on options are replete with examples of famous traders that got killed that depended on this strategy for their bread and butter. But even then, maybe there are traders out there who have done this strategy for decades and have risk management procedures in place (possibly buy or sell stops on the underlying futures to hedge a major move), that can win doing it. It just scares me to try to depend on this strategy - to sell wings.
Futures options allow much less margin requirement for the premium received. You can easily sell 30-40% OTM and still receive a good premium, unlike equity/index options, which require you to sell close to the money and for a large margin requirement. This goes without saying, risk management is key. Cut the losses, let the winners run. Since being short on options means knowing your maximum profit, you know ahead of time what you are going to make. Setting up a double premium mental stop loss cuts all losses to just that. Double premium.
In my opinion, honestly I feel the strategy I use is far safer than anything I have ever done, be it stock investing, stock option trades, forex, or futures trading. There is no other security I can think of which allows me to be wrong and still make a profit.
I hardly pay attention to the greeks as they just give me some stats on what I am getting into. They do not determine anything for me. I do keep delta and theta on my position interface, however.
Your positive theta strategy can be crushed by a big move against you and a corresponding increase in negative vega even with a fair degree of time left to expiration.
This may be true for stock options, no doubt. But with futures options, I haven't looked at vegas at all, because it seems a lot less sensitive to volatility, so much so I don't bother with it.
Also, being short on options means you are NEGATIVE THETA. Not positive.
