From Zero Hedge:
The EU assembly just voted affirmatively to impose a spate of rules to control ‘high-frequency-trading that, as the WSJ reports, was advanced by Germany following their concerns that speedy traders have brought instability to markets. It is somehow reassuring that three-years after we first brought HFT to the mainstream’s agenda, at least one nation is taking it seriously, doing something about it, instead of being filibustered into the ‘liquidity-providing’ meme. The rules will initially require registration, collect fees on excessive use of HFT methods, and install circuit breakers with the goals to “limit the risks associated with high-frequency trading” per a senior German FinMin; but the more stringent rules to come will have the greatest impact as they intend to include requirements for orders to rest on the exchange book for at least half-a-second, and potentially order-to-trade ratio caps. Not surprisingly, the HFTs believe a “one-size-fits-all approach would be very harmful.” Indeed – to their profits.
