Oh yes I do believe there is a major correction in the queue. VXX will make a lot of people a lot of money when it happens. Til then the safe bet is to just play the calls for intra day trades and maybe hold them for a few days when there are major events such as terrorism, supply disruptions and market volitility in general. Also, if you bet big, try to stay 1 or 2 strikes in the money so you have a chance to get out if the play goes south on you.
