华尔街高科技交易员令人担忧

    《暗池交易》介绍了股票交易的新世界，是一本颇具娱乐性、简单易懂的书，尽管帕特森的标题有些误导。他用了概括性术语描述了整个美国市场，而暗池从技术上讲只是一个细分市场，在其中进行的买卖交易都避开了公众视线。

    更棘手的问题是，帕特森没有解释如何防范高频机器人和具有学习能力的先进算法，避免它们引发新的股市崩溃。揭露了我们所面临的可怕现实，详细阐述了推动股市的各种力量是一回事。但要找到解决方案则是另外一回事。

    因为，这个问题根本就没有简单的解决办法。不幸的是，证券交易管理委员会（SEC）在管控方面已经滞后，但个别的高频交易员是不会兴风作浪的，这就像一家银行的倒闭不会使整个系统陷入瘫痪。看来，要想了解如何监管美国股市——这个新兴的狂野西部，我们或许不得不等待作者的下一本书了。

    Dark Pools is easily the most entertaining and accessible book to cover the new world of stock trading, even though Patterson's title is misleading. He uses the umbrella term to describe the entire U.S. market, although dark pools are technically sub-markets that mask buy and sell orders from public view.

    A bigger problem is that Patterson doesn't explain what will prevent high-frequency robots and advanced-learning algorithms from causing the next market collapse. It's one thing to detail the scary new reality in which these forces drive our stock market. It's another to offer solutions.

    That's because there are no easy fixes. The SEC is woefully behind in regulating, and individual high-frequency traders aren't problematic, just as one bad bank won't cripple the system. We may have to wait until his next book to learn how you police the new Wild West, more commonly known as the U.S. stock market.
