It will come as no surprise to any ZeroHedge readers but High Frequency Trading (HFT) deeply concerns Erik Hunsader, founder of Nanex. He worries that today’s investors, our regulators, — heck, even the HFT algorithms themselves — don’t fully understand the risks market prices face in the brave new era of bot-dominated trading. For instance, Hunsader estimates that HFT algorithms are responsible for 70%(!) of all completed transactions on our exchanges, and for 99.9%(!!!) of all exchange quotes. The pictures of trading floors you see on TV, where the people in bright jackets appear frantically busy in making their trades, have no bearing — claims Hunsader — on the actual trading action. The real action happens across fiber-optic cables, on racks of servers in cooled rooms; where an arms race defined by cable length and switching speeds is being waged. The reality is that the machines have taken over.
