Amazon Summary
Four years after his #1 bestseller The Big Short, Michael Lewis returns to Wall Street to report on a high-tech predator stalking the equity markets. Flash Boys is about a small group of Wall Street guys who figure out that the U.S. stock market has been rigged for the benefit of insiders and that, post–financial crisis, the markets have become not more free but less, and more controlled by the big Wall Street banks. Working at different firms, they come to this realization separately; but after they discover one another, the flash boys band together and set out to reform the financial markets. This they do by creating an exchange in which high-frequency trading―source of the most intractable problems―will have no advantage whatsoever. The characters in Flash Boys are fabulous, each completely different from what you think of when you think “Wall Street guy.” Several have walked away from jobs in the financial sector that paid them millions of dollars a year. From their new vantage point they investigate the big banks, the world’s stock exchanges, and high-frequency trading firms as they have never been investigated, and expose the many strange new ways that Wall Street generates profits. The light that Lewis shines into the darkest corners of the financial world may not be good for your blood pressure, because if you have any contact with the market, even a retirement account, this story is happening to you. But in the end, Flash Boys is an uplifting read. Here are people who have somehow preserved a moral sense in an environment where you don’t get paid for that; they have perceived an institutionalized injustice and are willing to go to war to fix it.

For those interested in a more detailed account, Lewis' Flash Boys is a really great book. http://www.amazon.com/Flash-Boys-Michael-Lewis/dp/0393244660

_Flash Boys_ is a terrible book. It's incoherent, very poorly ties the narrative about this case to HFT, gets a lot of trading details wrong, and makes an underdog story out of an attempt by a bunch of bigbank insiders to route bigbank brokerage trade through their new firm. If you're interested in the technical story behind HFT, a much better thing to read is that series of articles that's been running on HN for the last few months.

I'm a Michael Lewis fan --- I even liked _Next: The Future Just Happened_ --- but this book was so disappointing I've actually become disillusioned. What else was he wrong about that I wasn't clued in enough to notice? Do Greek people in reality try hard to pay their taxes? Was Chad Bradford a terrible deal for the A's? Was Marillion a terrible band?

The book "Flash Boys" by Michael Lewis chronicles the rise of HFT, and basically argues that it doesn't really provide that much of a benefit.

Suggest you read this rebuttal. Lewis' book is deeply flawed. http://www.amazon.com/Flash-Boys-Insiders-Perspective-High-F...

Standard PSA about "Flash Boys". If you are interested in HFT you are better off quite literally not reading that book than reading it. It is very biased and largely inaccurate.

If you want to read narrative non-fiction about HFT, "Dark Pools" by Patterson, which also has its mistakes, is much better.

Are there any other resources you can recommend for learning more about HFT?

There are several books which speak about HFT at a high level. If you are curious about the actual mechanics of stock exchanges and (a bit about) how various parties make their money, I wrote a bit about it at http://falconair.github.io/2015/01/05/financial-exchange.htm...

For blog post style reading 'yummyfajitas' series on HFT is good:

https://www.chrisstucchio.com/blog/2012/hft_apology.html

For technical books:

- Trading & Exchanges by Harris (a little out of date)

- Algorithmic Trading & DMA by Johnson.

On the narrative non-fiction side Dark Pools is basically it.

Great, thanks!

I would also recommend reading "Flash Boys: Not so Fast" (http://www.amazon.com/dp/B00P0QI2M2).

Written by a high frequency trader. Are there any third parties that have deeply explored HFT and come out in defense of it?
kasey_junk
Sure. Vanguard has the widely publicized view that HFT helps to bring down the cost to retail investors for instance

This is a really fun read. Thanks for pointing it out!
http://www.amazon.com/Flash-Boys-Michael-Lewis/dp/0393244660 is a great high level overview on this whole issue (including brad katsuyama).
The book Flash Boys provides a solid understanding of how HFT got started. http://www.amazon.com/Flash-Boys-Michael-Lewis/dp/0393244660
kasey_junk
No it doesn't. Everyone I know with HFT industry experience that has read it (including myself) has panned it. It is possibly the worst thing you can read if you are interested in how HFT works. "Dark Pools" has it's own faults but for narrative non-fiction it is the only game in town.

Micheal Lewis explains dark pools and HFT's quite well in his new book Flash Boys [1].

No he doesn't. Either through ignorance, incompetence, or malice he wrote a pretty terrible book about dark pools and HFTs. Dark Pools by Patterson is much better and even it misses on lots of details.
