I just wanted to add something very briefly, but worth stating, there is an OPTION for just about every strategy out there. The real question is, do you have an underlying strategy? Options are the most effective if you first build a skeleton of a strategy then look for particular options with which to flesh it out. OTM calls/puts have their place as well as writing calls and puts. Options expiring worthless is a GREAT thing depending upon your strategy. The question is, do you REALLY HAVE a basic strategy to employ?
Are you just trying to collect premiums, or is your use of option to hedge current positions?
Buying and writing calls/puts have their places, just have to know what you are after.
