I tried something similar for about a month, and it is one of those things that for me seemed better on paper than in practice.
Although don't let my negativity or lack of skill discourage anyone.
Other than the rule prohibiting being on the bid and ask at the same time, which is reason enough there are other issues.
I have some Qs in my account that I sell calls against, one of the most liquid options contracts out there.
If I sell and prices go up, why cover, I want rid of the things anyhow, not to mention time works in my favor.
If I buy back and prices drop, why not just resell, time decay works in my favor.
There are a bazillioon contracts sitting on the bid and ask so you are really at the MERCY of the market maker. Not to be critical, but it would seem that sometimes you only get the fills you don't want. And they just don't come that often, even when my contracts hit a nickel, I have had bids sit for a day or more.
I have tried to augment this strategy by buying the contracts back when they decay, looking for a rally to resell them. But I would say especially over the past year this is at best a wash and I have found that some months I have bought them for a dime only to sell them back for a nickel.
Finally, volatility sucks, I figure at best I will write 1/2 of the premium I wrote last year, so there is really less option to trade.
Just what I found, others may have better luck.
