The Option Trader Handbook: Strategies and Trade Adjustments (Wiley Trading)

The other reviews point out the highlights of this book. I do think this is a worthwhile addition to any intermediate option trader, but I have to say if you are a net option seller there is little direct reference to your strategies. Still lots you can take from it, but not so much directly to your strategies. If you want to learn what to do when the call spread you sold is being threatened, you are not going to get a lot directly related to this. That being the case, buy and learn from it anyways as you will pick up or remember stuff that will make you a better trader.
