 High-frequency traders employ algorithms to look for patterns in the market and exploit them. An important part of this is Low Latency Trading which uses computers that execute trades within milliseconds. The bots that do the trading at millisecond speed are written by financial-mathematicians called Quants. High-frequency traders employ algorithms to look for patterns in the market and exploit them.

Algotrading includes statistical arbitrage, but includes techniques largely based upon speed of response, to the extent that some ATQs modify hardware and Linux kernels to achieve ultra low latency.

 +==== Lightspeed not fast enough. ====
 +
 +<blockquote>
 +The latency disadvantage of globally distributed markets can't be entirely erased by technology, but the comparative lag times for international stock trades in general can be lessened by employing intermediate trading points. Alex Wissner-Gross, a physicist at the MIT Media Laboratory and Cameron Freer, a mathematician now at the University of Hawaii, propose to blanket the world with computer stations positioned along the paths between all of the major stock markets.\\
 +\\
 +Securities trading companies could put semiautonomous computers at these strategic crossroads. Programmed with sophisticated buying and selling instructions these computers would act much more promptly to price signals coming from remote markets than if the signals had to travel all the way to the home office.\\

 +==== the 400ms news leak ====

 +"On January 31, 2013, approximately 400 milliseconds before the official release of the EIA Natural Gas Report, trading activity exploded in Natural Gas Futures and ETFs such as UGZ, UNG and BOIL." http://www.nanex.net/aqck2

 +
 +"Veteran traders would usually wait in anticipation for the weekly report of gas-inventory figures by the U.S. Energy Information Administration released on Thursday at 10.30 AM and then dive into the busiest trading window of the week. This is no longer true as most traders are now staying out of the market due to the HFTs new strategy - sending floods of orders in an effort to trigger huge price swings just before the data gets released, also known as “banging the beehive”.
