I read John Murphy's book Intermarket Technical Analysis over the last couple of days, and I found it quite intriguing how all those markets interact and fit together. It seems reasonable (or at least interesting) to use at least some of these ideas in an attempt to get the "big picture": where the markets are headed in the next couple of months or even years and why. Actually, I thought the same when I read Larry William's book about the COT data some weks ago: if you really understand that stuff (and I mean not just the theory behind it, but when you have incorporated it into your view of the market as a whole) then you are just a little ahead of most other guys out there. Same goes for some other things like Put/Call ratio, VIX or market breadth in general. So, is anyone of you actually using this sort of information? Is it a fixed part of your trading plan or are you ignoring it completely (and if so, why)? Where are you getting data, charts, comments from? What books can you recommend? Or is it all rubbish?
