HFT could be curbed simply by raising the execution price for each consecutive trade a firm makes in an hour (or even in a minute). Won't affect most traders, but HFTs would become more expensive. There's really no incentive for the exchanges to do this, since they're raking in millions in co-location fees and they're able to claim lower execution times for most trades.
