A very unique trading book that I would recommend to anyone in the business. The author is definitely very qualified and effectively shares his framework of macro trading to the reader. There aren't very many books out there that do this. You don't necessarily have to agree with everything in his framework, but can take pieces here and there for your own improvement which is what the author intends. His trading style is definitely geared towards the longer term (a few years).
The book is split into three parts. In the first part, he discusses the qualities that he thinks makes an individual trade a good one. Among the qualities that he places emphasis are going with the trend and positive carry. He really points out that fighting against carry in most situations is a lost cause. It's clear that the author doesn't prefer the "fading" type of trades.
The second part discusses execution of the idea. It gets a little interesting here. The author doesn't seem to believe in the traditional notion of placing stops. His main argument is that too often, traders will get whipped around even their idea is correct. I can't say I agree with him, but given his trading horizon, it does make sense. His alternative is to simply cut down the position size. In this section of the book, he also goes into his sizing of his positions and how he trades specific markets (ex. adds to FX positions as they go in his favor vs. adds to interest rate positions as they go against him).
Finally, the third part of the book is probably the most unique and insightful. The author discusses what makes a trade dominant. He introduces us to "concurrent necessity". Macro trades are often linked and there is always a dominant trade (necessary).
He uses basic mathematical logic to argue his case. If A implies B, but B doesn't imply A, then B is the necessary. If being a salmon implies being a fish, but being a fish doesn't imply being a salmon, then being a fish is necessary. With regards to a trade, he uses the case shorting US front end rates vs. shorting EURUSD in 2014. He argues that shorting US front end rates is A, while shorting EURUSD is B. If the Fed tightens at a faster pace, then the dollar will rally (A implies B). However, if the dollar rallies, it does not necessarily mean higher US front end rates (B doesn't imply). Thus, shorting EURUSD (B) is the dominant trade. As a trader, you should always be seeking dominant trades.
To conclude, he calls the perfect a trade, a combination of two trades that share the qualities he has discussed in the book, but which neither may fail with the other succeeding.
It's a pretty quick read and definitely worthwhile for anyone in trading.
