Substantial development of information technologies (IT) stimulated the beginning of "electronic revolution", which allowed market participants to use all the accessible market services without the need of physical presence in exchanges centers. For relatively short period of time, IT led to dramatically increased automation of order-execution process.From the end of 1990s, the electronification of market orders' execution made it possible to transmit orders electronically, but not by telephone, mail, or in person, as it was before that, and, as a result, the biggest part of trading on modern world financial markets is implementing by internet and computer systems (Chlistalla, 2011). This fact, obviously, made it possible to use different trading algorithms widely in everyday trading practice.
