High frequency trading crop circles. Automated trading is flooding stock exchanges with nonsensical orders making odd patterns like The Knife at millisecond scales. Bugs, emergent phenomena, or market jamming strategies? No one seems to know.

Major market indices fell almost 10% this afternoon before recovering half of that value. Some blame the failing Greek economy and the related loss of confidence in the Eurozone. But a lot of attention is being paid to the role of automated trading systems. Accenture's stock, for example, dropped from $41 to one penny in two minutes and then recovered just as quickly. Will this trigger a loss of confidence in automated trading?

An idea to support the U.S economy. The suggestion is that everyone American should buy 10 or 20 shares in their favourite stock on Monday, and in doing so support their country in the time of crisis. It sounds like a good idea to me. (The story is at the bottom of the page)

NBCi relaunches as probably the most boring, blase portal site I've ever seen and their stock goes up? Is it just me, or does it look like they bought the site from "Al's Do It Yourself Portals"?
