As kasey_junk mentioned, availability is on an exchange basis, so I'm not sure if all exchanges provide this service. I was talking about the sophistication of low latency trading in Canada and that only. In the states, there aren't a ton of exchanges and ETN and dark pools, with different matching engine rules and all that crap. If I am a sophisticated low latency firm, I wouldn't want any exchange added 'extras' to get in the way. IMHO, I think retail investors are better served and have less chance of being thrown on a roller coaster ride by runaway algos in Canada compared to the U.S., and that's a good thing.
