Larry it always depends on what options you're trading. and what the stock is too. if you're a careful trader you can do fine...nothing to be scared of at all.. options do not trade after hours...so you need to understand the current direction of the stock, sector and indexs... i always use limit orders for options anyway..if you get filled fine if not not... and Larry you can "always" get out of any trade during market hours by just selling "at the market" if need be... hope that helps
