You have no idea just how bonkers high-frequency trading is making the stock market until you actually see it in action. A terrifying new video by ...

The trading risks of HFT may decimate the HFT operation and at the same time greatly affect other market participants. Particularly, in selected markets, unchecked HFT may quickly incur considerable losses, well in excess of any tolerable limits.

More than two years since the "flash crash" sent investors fleeing the stock market and nearly a year since the Facebook IPO imploded, the Securities ...

The frustration of those of us arguing for pragmatic reforms and unbiased research should be evident. I am thankful that here in the United States, the SEC has at least begun to realize the need for more independence in its research and panels, and I hope that trend continues.

They want to think that machines are biddable and programs run smoothly. But with traders and market makers creating and deploying new systems and algorithms constantly, the danger of something going wrong is inevitable.

We have no shortage of great ideas for how to help dampen or eliminate the ill effects of high-frequency trading. We simply lack the will and the ability to push meaningful reform through our corporate-controlled, hyper-partisan government.

While it is true that HFTs have a vested interest in keeping market abuse to a minimum, it is not yet clear that their liquidity has been healthy enough to withstand the pressure of incoming regulations.

In the low-latency world of high-frequency trading, some will lose, no matter how smart their systems and people. Can you catch up? Or should we slow them down?

The Borsa's solution, especially if it is embraced by other trading destinations, may spawn a new generation of intelligent "sensing" algos.

With the high frequency-obsessed trading community, speed is essential. And social media, particularly Twitter, is becoming a key source of high-speed information for feeding trading algorithms.

With all due respect to Mr. Gore, I don't think he understands what algorithms really do. Algorithms are programmed by people, and it is people that are taking the short term view.

Many high-profile long-term investors have publicly expressed their frustration with the tactics of some high frequency traders (HFTs). While much of...

A new book will prove indispensible for those interested in the problems and benefits of replacing human traders with algorithmic machines -- in one of most important markets in the world.
