Here is another thought. Many people think that the rapid computer trading does not really add any value to the market in any case since there is no long term investment.
It clearly doesn't. A proposal that's been kicking around for a while is to clear all trades once a second, so everyone has plenty of time to get them in no matter where they are. This has no chance of going anywhere, of course, until there's enough software disasters to provide political pushback against the leeches doing high speed trading. There is a new data center in Keflavik, Iceland. They advertise all of its fabulous green characteristics, e.g., power is from geothermal, and A/C is by opening the window, but it also happens to be closer to New York than anywhere in Europe, and closer to London than anywhere in North America, with good cable connections to both.
