comment Is the Interactive Brokers API suitable for hft?
gndt.com and limebrokerage.com is probably as close as you can get but you'd have to do significant volume in order to get a commission structure that lets you take advantage of any short term opportunities

defining hft as anything less than 5-10 mins is not typical in this industry, cause that could also refer to day trading just a few names which no one i know would refer to as hft.
