So, here we and here. The community was separated and was created fork Bitcoin which will mention as the software, and, perhaps, a chain of blocks. Two parties of opposition – Bitcoin Core and its a little changed version – Bitcoin XT [the author of article, Mike Hearne, are her main developer; the main change in Bitcoin XT is an increase in a limit at the size of blocks – a lane comment]

Раcследование: Как 15 октября 2014 года высокочастотные трейдеры обвалили рынок казначейских облигаций США и манипулировали им

1 year, 6 months ago
От переводчика: блоге технологиях, связанными с трейдингом на современных биржах. Материал, который мы предлагаем вашему вниманию сегодня, был опубликован на площадке Zero Hedge – ее авторы подчеркивают свою независимость от «ангажированных финансовых журналистов» и стремятся рассказывать о том, что, по их мнению, на самом деле происходит на финансовых рынках. В статье они решили рассказать о «темной стороне HFT» – по их мнению, именно алгоритмы высокочастотной торговли стоят за обвалом рынка казначейских облигаций США в прошлом году.

Мы сильно удивились, когда узнали, как некоторые пытаются интерпретировать сегодняшний [от 13 июля 2015 года – прим. перев.] долгожданный отчет, подготовленный совместно Министерством финансов, Федеральной резервной системой (ФРС), Комиссией по ценным бумагам (SEC) и Комиссией по торговле фьючерсами США (CFTC). Целью отчета была попытка «объяснить» мгновенное снижение доходности казначейских облигаций 15 октября 2014 года, когда, если помните, примерно в 9:34 утра наблюдался резкий скачок цен на казначейские облигации и снижение их доходности с 2,20% до 1,95%…





… а составители отчета постарались сделать все, чтобы отвлечь внимание читателей от высокочастотного (HFT) трейдинга.

Похожий случай: чуть ранее Wall Street Journal заявил о том, что «Власти США пришли к выводу, что небывалая волатильность цен на рынке казначейских облигаций США 15 октября 2014 года была вызвана «рядом факторов». При этом они указали на масштабные изменения в структуре рынков казначейских ценных бумаг, включая растущую роль высокочастотной торговли».

1 year, 6 months ago
Note of the translator: In the blog technologies, connected with trading at the modern exchanges. Today we present to yours the second part of adapted translation of article of the London financier and trader Brett Scott in which he in detail tells about the phenomenon of high-frequency trading (HFT). This material will help to understand better all pluses and the negative moments arising owing to activity of such high-frequency dealers. The first part is available according to the link.



You see only what you want to see.

To me in some sense all the same, "undermine" HFT algorithms activity of the markets or not. Partly it because I do not consider the markets as any sacred mechanism which works for the benefit of all mankind, and, therefore, cannot be profaned. I to the fact that the markets already long time are a subject of systematic abuse when those, who have more power, can use the act of an exchange (obviously, not having any relation to policy) for benefit extraction.

But give for a second it is representable that the market infrastructure also really possesses a certain mystic force which positively influences society. What then for this purpose does HFT trading? One of arguments of his supporters consists that HFT trading promotes growth of liquidity in the markets of different financial instruments. This statement is supplemented with the menacing news of what can occur if this liquidity falls. Low liquidity of the market will strongly be reflected in pension of your grandmother!
