Stock or Index in last week

Hi All,

Just wondering if you have or follow any set of rules w.r.t expiration date/remaining time when it comes to option writing.

Would you sell a strangle/straddle in last week or last two weeks for a stock (lets say liquid). And, what about OTM strangles ?

Is it easy to get out of trades in last day or bid ask spread gets so much that its not worth to do so.
