High Frequency Trading

If “Broken Markets” failed to identify the definition of high frequency trading (HFT), this book started with an impressive classification of HFT strategies as follows:

-         Automated liquidity provision: Quantitative algos for optimal pricing and execution of market-making positions. (Holding period < 1 minute)

-         Market microstructure trading: Identifying trading party order flow through reverse engineering of observed quotes. (Holding period <10 minute)

-         Event Trading: Short term trading on macro events (Holding period < 1 hour)

-         Deviations arbitrage: Statistical arbitrage of deviations from equilibrium: triangle trades, basis trades, and the like. (Holding period < 1 day)

Finally, there is someone who not only tried to define HFT precisely. In fact, she pointed out various possible parties that involved. Hence, I was kind of attracted by the first few chapters. However, the more I dig in, the more I found I am not reading the right book. At the end, the introduction is good. But the expansion and further elaboration do not match the topic precisely. (The content in the “microstructure” section tells the whole story). Furthermore, the book itself already hard to digest. (IMHO… not a well-organized book) Then, the author add up tons of formula which I myself do not see the necessity of it.

Having said that… I do not actually rate this book extremely low. In fact, I am giving 4/10 as I could still unlock some gems throughout the book. The contents may stray off the main topic at times. But, overall, it is not a bad book to burn out our leisure time…I guess FHT is still a protected animal in the world of investment. After all, there are various parties with separate self-interest. As such, it is rather hard to find a book that tells the truth and the whole stories. Irene Aldridge tried hard in this book. But, it just fails to convince me…
