Quote from Jahajee:
Let's say you are writing naked SPY or SPX OTM puts.
For each put written, put in a stop order - ES or SP futures, that will kick in if the market tanks, especially during overnight session.
e.g. sell SPX 1220 puts
Put in a sell stop order at 1225 or 1230 etc; this value will be estimated based on the PUT strike. You can adjust the stop as time goes by.
Lots of suggestions but people are clearly not familair with crash scenerios. Your scenerio assumes markets CRAWL lower. Answer whether markets ever gap or crash and whether VOL ever spikes and you will see the stop order method is like catching a falling elephant with a handkercheif.
