Not anything super NEW - but I saw a TV show about a hedge fund /Institutional guy who was pissed about the HFT algo's companies causing him to get worse fills for his clients - since the technology is based on very shot time frames finding inefficiencies in quote flashing/update/queue caused by physical sever distance from the exchange - this guy had a BRILLIANT startup idea in which he created a "REDUCTION LOOP" -
Basically he created an EXCHANGE that purposely puts execution of orders into some sort of a "DELAY" - so instead of 2 milliseconds it could be 400millisecond of order/queue execution - then a few hedge fund would connect only to that exchange and trade between themselves leaving the HFT companies "in the dust"
