High-frequency trading - Wikipedia, the free encyclopedia:
"High-frequency trading (HFT) is a type of algorithmic trading, specifically the use of sophisticated technological tools and computer algorithms to rapidly trade securities. HFT uses proprietary trading strategies carried out by computers to move in and out of positions in seconds or fractions of a second. Firms such as British-based Algorates, one of the first to employ HFT, rely on advanced computer systems and the processing speed of their trades to record high earnings in the market. "
