Query: The IRS will love this book.

I read 3/4 of this book last weekend. Not a single novel idea to be seen. Essentially no details, other than the incredibly repetitive ramblings about his life and the myriad of other products Cook would like to sell us. If you enjoy infomercials on TV, you'll love this book. No discussing of any downside risk (oh, well maybe two sentences worth, just to make the lawyers happy). Most amazingly, no discussion of the tax implications of trading using these techniques. If you've never heard of the IRS's "wash-sale rule" you are going to be in for a rude surprise come April 15th.
