Oh NO! Another problem with stop loss orders, is that when they trigger, they become market orders. They don't necessarily, or even often, trade at the point you set your stop. And options like these with lifetimes measured in hours are always very thinly traded.
Suppose (just because I find it easier to play with numbers) you sold 10 covered $257.5 weeklies for $2. At this instant, they might be around $1. So you think, "Gee, I'll put a stop loss buy-to-close order at $1.50, lock in at least a 25% profit even if the stock goes up." Now, some reckless person for reasons only he knows, offers to buy for $1.50, and his trade happens, and triggers your stop loss order. Now you have 10 contracts on the books, which the computer will happily fill, even though the only other sellers are at $10! You just lost 4 times what you invested originally.
Since you sold a covered call, if you just sit on it until it expires, the worst that happens is that you miss out on any profit on those shares if the stock price goes over $259.50 (strike plus what you already pocketed). There are worse things...
I am another person who is in the camp of staying far away from stop loss orders ever (again). It's like trading on your emotions, except without even the benefit of taking a deep breath. And I'm not just talking about options.
