Systematic Trading

I'm reading a pretty fascinating book, Profitability and Systematic Trading by Michael Harris. It strikes a good balance between basic and advanced stuff.

As befits a systems guy, Harris strongly rejects the notion that the market is some kind of independent entity above and beyond its participants. According to him, "any attempt to assign a special or absolute quality to the word market, other than the fact that it is the collection of its participants, is a distortion of reality and may eventually lead to false trading or investing decisions."

It is true that many traders (and most discretionary traders) have an almost mystical relationship with "the market" and when they watch intensely those wiggles on the daily (or the 5-minute) chart, they see (or think they see) more than the end result of different trades coming from different market participants. They almost see a living organism going this way and that, and try to anticipate where the wild beast is going next.
